Pull-Through Failure Tests of Thin Steel Roof Battens under Wind Uplift Loads
Science & Engineering Faculty, 2020Co-Authors: Mayooran Sivapathasundaram, Mahen MahendranAbstract:Thin profiled steel roof sheeting and battens are increasingly used in the construction of roofing systems of residential, commercial, industrial and farm buildings in Australia. The critical load combination of external wind suction and internal wind pressures that occur during high wind events such as thunderstorms and tropical cylcones often dislocate the roofing systems partially or even completely due to premature roof connection failures. Past wind damage investigations have shown that roof sheeting failures occured at their screw connections to battens. In most of these cases, the screw Fastener Head pulled through the thin roof sheeting whilst the screw Fasteners also pulled out from the battens. Research studis undertaken on the roof sheeting to batten connection failures have improved this situation. However, the batten to rafter or truss connections have not been investigated adequately. Failure of these connections can cause the failure of the entire roof structure as observed during the recent high wind events. Therefore a detailed experimental study consisting of both small scale and full scale tests has been undertaken to investigate the steel roof batten pull-through failures in relation to many critical parameters such as steel batten geometry, thickness and grade, screw Fastener Head sizes and screw tightening. This paper presents the details of this experimental study and the pull-through failure load results obtained from them. Finally it discusses the development of suitable design rules that can be used to determine the pull-through connection capacities of thin steel roof battens under wind uplift loads.

Development of Suitable Strengthening Methods for Thin Steel Roof Battens Subject to Pull-Through Failures
Journal of Architectural Engineering, 2018Co-Authors: Mayooran Sivapathasundaram, Mahen MahendranAbstract:Failures of the connections of thin-walled steel roof battens to rafters or trusses were increasingly observed in the form of a localized pull-through failure in the batten bottom flanges during recent extreme wind events. Therefore, an extensive research study was conducted to investigate this local connection failure, and suitable test and design methods were developed to accurately determine the design pull-through capacities of roof battens. The study also showed that optimizing the batten geometry is unlikely to increase the pull-through capacity of batten connections to rafters or trusses because they essentially depend on the diameter of the screw Fastener Head, batten thickness, and steel ultimate tensile strength. Hence, the study was extended to develop suitable strengthening methods to delay or prevent this critical localized connection failure and thus enhance the pull-through capacity. This article first presents the investigations of some current roof construction practices recommended and used by roof batten manufacturers and builders, then proposes the details of suitable strengthening methods. Detailed experimental investigations were undertaken for this purpose, and their results and discussions are presented in this article. In addition, suitable capacity-improvement factors are proposed for the strengthening methods to accurately determine the design pull-through capacities of roof batten connections to rafters or trusses.

Numerical studies and design of thin steel roof battens subject to pull-through failures
Engineering Structures, 2017Co-Authors: Mayooran Sivapathasundaram, Mahen MahendranAbstract:High wind uplift loads acting on the light gauge steel roofing systems during tropical cyclones and storms frequently cause premature failures of roof connections, which lead to extensive damage to roofing systems. Such roofing system damage was observed in recent cyclones due to premature failures of steel roof batten to rafter/truss connections. They were mostly observed to be due to a localised pull-through failure in the bottom flanges of roof battens. Hence a series of small scale and full scale tests of roof battens was first conducted to study their pull-through failures. To further enhance the understanding gained from the experimental study and to predict the pull-through capacities of a wide range of roof battens, finite element models were developed and analysed using a suitable failure criterion. This paper first presents the applicability of the failure criterion for different roof batten geometries and screw Fastener Head sizes. Then it provides the details of a numerical parametric study conducted to study the pull-through failures of roof battens in relation to influential parameters such as batten geometry and screw Fastener Head sizes. Finally, this paper proposes suitable design equations and capacity reduction factors for the calculation of the design pull-through capacities of thin-walled steel roof battens.

Numerical modeling of thin-walled steel roof battens subject to pull-through failures
Science & Engineering Faculty, 2017Co-Authors: Mayooran Sivapathasundaram, Mahen MahendranAbstract:Extensive damage to light gauge steel roofing systems caused by high wind events such as cyclones and storms has been a concern to the communities living in cyclone/storm prone areas over many years. In recent times, pull-through failures of roof battens occurring in their bottom flange to rafter or truss connection have become the main reason for severe roof failures. Therefore a detailed experimental study was first undertaken using full and small scale tests to investigate the pull-through failures of roof battens subject to high wind uplift loads. However, since experimental tests can be expensive and time consuming, the ability of successfully using numerical models is imperative. Hence a detailed numerical study was undertaken by developing suitable finite element models with the inclusion of a suitable failure criterion to predict the initiation of critical pull-through failures of roof battens that are associated with a tearing fracture around the screw Fastener Head edge. The overall load versus deformation behaviour, ultimate failure loads and failure modes were compared with the experimental results to validate the developed finite element models. The ability of the validated finite element models to accurately predict the pull-through failure loads of roof battens for other cases was evaluated by comparing relevant experimental results. This paper presents the details of this numerical study and the results.

Experimental studies of thin-walled steel roof battens subject to pull-through failures
Engineering Structures, 2016Co-Authors: Mayooran Sivapathasundaram, Mahen MahendranAbstract:Despite the increasing usage of thin and high strength steel roof battens in the roof structures of low-rise buildings, recent cyclones and storms have shown that they prematurely fail at their screw Fastener connections to the rafters or trusses due to the screw Heads pulling through the batten bottom flanges. Such pull-through failures can lead to catastrophic failures of the entire roofing systems as observed during recent high wind events. Therefore a detailed experimental study consisting of both small scale and full scale tests was undertaken to investigate the pull-through failures of roof battens under wind uplift loading in relation to many critical parameters such as screw Fastener tightening, roof batten geometry, batten thickness, steel grade, screw Fastener Head size and screw Fastener location. Effects of underside surface and edge details of the screw Fastener Head, and screw Fastener types were also considered. This paper presents the details of the tests conducted in this study and the pull-through failure load results obtained from them. Finally it presents the details of suitable design rules and capacity reduction factors developed in this study that can be used to accurately determine the design pull-through capacities of steel roof battens under wind uplift loads.

effect of Fastener under Head contact on the early stage of self loosening of preloaded countersunk Fasteners subjected to cyclic shear loading
ASME 2014 Pressure Vessels and Piping Conference, 2014Co-Authors: Amro M Zaki, Sayed A NassarAbstract:Three dimensional Finite Element model is used to investigate the loosening behavior of countersunk threaded Fasteners subjected to cyclic shear loading applied through prescribed transverse excitation to the Fastener Head. Fasteners with conical Head profile require precision machining of both the Fastener Head and the mating joint hole. Any mismatch between the Head and the joint conical angles affects the torque tension relationship as well as the loosening performance. Investigation focuses on the loosening behavior in its early stages. Factors investigated include the effect of the bolt Head/joint hole contact location, joint elastic modulus, and tapped hole clearance for different combinations of thread fit, on the loosening performance of preloaded countersunk-Head bolts. The FEA model prediction of the self-loosening behavior is experimentally validated.Copyright © 2014 by ASME

A Numerical Investigation of Bolt UnderHead Temperature Evolution Under Various Fastening Conditions
Tribology Transactions, 2008Co-Authors: Laila Guessous, Gary Barber, Sayed A NassarAbstract:The temperature rise that occurs due to frictional heating under a turning Fastener Head during the tightening process of bolted joints can have a significant effect on surface and thread wear and galling. In the present study, the spatial and temporal temperature rise in a bolt during the tightening process is numerically investigated for a variety of sliding and loading conditions. The effect of tightening speed, angle of turn, and frictional energy input is numerically investigated. Tightening speeds were varied between 1 rpm and 3000 rpm and the angle of turn was varied between 15 and 720 degrees past free spinning. Significant temperature rises of the bolt underHead were observed computationally for higher tightening speeds and angles of turn and the potential for localized melting or near-melting temperatures was shown. In the case of lower tightening speeds, the temperature rise was not as dramatic, but temperature increases are then observed along the length of the shank, showing the possibility o...

A Numerical Investigation of Bolt UnderHead Temperature Evolution During Tightening
ASME JSME 2007 Thermal Engineering Heat Transfer Summer Conference Volume 1, 2007Co-Authors: Laila Guessous, Gary Barber, Sayed A NassarAbstract:The temperature rise that occurs due to frictional heating under the turning Fastener Head during the tightening process of bolted joints can have a significant effect on surface and thread wear and galling. The subject has received little attention in the scientific literature. In the present study, the spatial and temporal temperature rise in a bolt during the tightening process are numerically investigated for a variety of sliding and loading conditions using finite difference methods. The effect of tightening speed, angle of turn, and frictional energy input is numerically investigated. Tightening speeds were varied between 1 RPM and 3000 RPM and the angle of turn was varied between 15 and 720 degrees past free spinning; this range of turn simulates joint stiffness variation from very hard to very soft joints. Significant temperature rises of the bolt underHead were observed for higher tightening speeds and the potential for localized melting or near-melting temperatures was shown. In the case of lower tightening speeds, the temperature rise was not as dramatic, but temperature increases are then observed along the length of the shank, showing the possibility of contributing to thermally induced galling between the threads. Due to the temperature variations observed in most cases in the underHead and along the bolt shank, this study indicates that such thermal effects should be considered when modeling the wear of bolted joints, particularly in cases involving larger tightening speeds or softer joints.Copyright © 2007 by ASME

Novel Formulation of the Tightening and Breakaway Torque Components in Threaded Fasteners
Journal of Pressure Vessel Technology-transactions of The Asme, 2006Co-Authors: Sayed A Nassar, Xianjie YangAbstract:New formulas are developed for the torque-tension relationship, various torque components, and breakaway torque values in threaded Fastener applications. The three-dimensional aspects of the lead helix and thread profile angles and the kinetic and static friction coefficients are all taken into account. Two scenarios of the contact pressure between threads and under the turning Fastener Head are considered, namely, uniformly distributed and linearly distributed contact pressure scenarios. The effect of thread pitch, lead helix and thread profile angles, friction coefficients, and Fastener geometry is discussed. Results from the new formulas are compared with the approximate torque-tension relationship provided in the literature. A percentage difference analysis indicates that the new formulas provide a significant improvement that would enhance the reliability and safety of bolted connections, especially in critical applications.

Effect of Tightening Speed on the Torque-Tension and Wear Pattern in Bolted Connections
Journal of Pressure Vessel Technology-transactions of The Asme, 2006Co-Authors: Sayed A Nassar, Ramanathan M. Ranganathan, Saravanan Ganeshmurthy, Gary BarberAbstract:In an effort to enhance the reliability of clamp load estimation in bolted joints, this experimental study investigates the effect of tightening speed and coating on both the torque-tension relationship and wear pattern in threaded Fastener applications. The Fastener torque-tension relationship is highly sensitive to normal variations in the coefficients of friction between threads and between the turning Head and the surface of the joint. Hence, the initial level of the joint clamp load and the overall integrity and reliability of a bolted assembly are significantly influenced by the friction coefficients. The effect of repeated tightening and loosening is also investigated using M12, class 8.8 Fasteners with and without zinc coating. The torque-tension relationship is examined in terms of the nondimensional nut factor K. The wear pattern is examined by monitoring the changes in surface roughness using a WYKO optical profiler and by using a LECO optical microscope. A Hitachi S-3200N scanning electron microscope is used to examine the contact surfaces under the Fastener Head after each tightening/loosening cycle. Experimental data on the effect of tightening speed, Fastener coating, and repeated tightening are presented and analyzed.

Numerical Investigation of the Evolution of the Heat Partition Factor During Bolt Tightening
Tribology Transactions, 2010Co-Authors: Laila Guessous, Gary BarberAbstract:The temperature rise that occurs due to frictional heating under a turning Fastener Head during the tightening process may result in changes in the mechanical and thermal properties of the bolt and workpiece and can lead to wear and even galling of the underHead and the threads of bolted joints. In order to properly model this temperature rise, it is important to properly account for the fraction of the interface frictional energy that is transmitted to the bolt Head. This study focused on numerically investigating the frictional temperature rise that occurs underHead during the assembly of a bolted joint and the evolution of the average bolt heat partition factor as a function of time. Numerical simulations were conducted for tightening speeds varying between 1 and 1,000 rpm and for different bolt/workpiece material combinations. The bolt heat partition factor was shown to vary with time but did not depend on the assumed tightening speed. Constant values of the heat partition factor may be assumed at hig...
