Engineering Geology for Society and Territory - Volume 3. River Basins, Reservoir Sedimentation and Water Resources - Multiple Load Case on Flexible Shallow Landslide Barriers: Shallow Landslide and Rockfall
Engineering Geology for Society and Territory - Volume 2, 2015Co-Authors: Wendeler Corinna, Glover JamesAbstract:Commonly a number of different gravity driven hazards (shallow landslide, rock slide, rockfall, small snow slides) will act at same location, threatening the safety of people, buildings and infrastructure. In this Case protection barriers have to be designed to cope with the different Load Cases of Multiple natural hazards (Fig. 77.1). The following covers the design challenges of a barrier project in Baltisberg, Switzerland, to protect a railway from both shallow landslides and rockfalls. Each hazard presents a greatly differing Load Case. Shallow landslides impact with spreading pressures Loading gradually, while rockfalls impact punctually with high velocities. Findings from a number of full scale barrier tests and a finite element simulation software FARO used in the design of flexible wire protection systems are presented.

Evolutionary structural optimisation based on boundary representation of NURBS. Part I: 2D algorithms
Computers & Structures, 2005Co-Authors: E. Cervera, Jon TrevelyanAbstract:This paper presents an evolutionary structural optimisation (ESO) approach based on the boundary element method. Non-uniform rational B-splines (NURBS) are used to define the geometry of the component and, since the shape of these B-splines is governed by a set of control points, use can be made of the locations of these control points as design variables. The developed algorithm creates NURBS-based internal cavities to accomplish topology changes. The optimum topologies evolve allowing cavities to merge between each other and to their closest outer boundary. Two-dimensional structural optimisation is investigated in detail exploring single and Multiple Load Case elastic problems.

Multiple Load Case on flexible shallow landslide barriers mudslide and rockfall
Proceedings of the International Conference on Road and Rail Infrastructure CETRA, 2014Co-Authors: Corinna Wendeler, Vjekoslav BudimirAbstract:Shallow landslides distinguish themselves with small failure depths or equivalently small volumes (up to 2 m or 200 m3 respectively). They release on steep slopes during intense rainfall and runout distances are usually smaller than a hundred meters. However due to their high bulk density and speed, shallow landslides represent a serious hazard to people, buildings and infrastructures such as roads or railway lines. The potential of damage is materialised through the pressure that they exert on objects during impact. The impact pressure is dependent on the kinetics and material properties of the flow as well as the geometry of the flow-object pair. Systematic study of full-scale shallow landslides was carried out at the Veltheim test site in Switzerland. Debris mixtures with volumes of 50 m3 were released down on 30° degrees steep and 40 m long slope on the hillside of a disused quarry. Mean front velocities between 5 and 11 m/s were measured, whil

3d and Multiple Load Case bi directional evolutionary structural optimization beso
Structural Optimization, 1999Co-Authors: V Young, G P Steven, Osvaldo M Querin, Yi Min XieAbstract:Evolutionary Structural Optimization (ESO), is a numerical method of structural optimization that is integrated with finite element analysis (FEA). Bi-directional ESO (BESO) is an extension to this method and can begin with minimal amount of material (only that necessary to support the Load and support Cases) in contrast to ESO which uses an initially oversized structure. Using BESO the structure is then allowed to grow into the optimum design or shape by both adding elements where the stresses are the highest and taking elements away where stresses are the lowest. In conducting this research, a methodology was developed (and integrated into the ESO program EVOLVE) which produced the optimal 3D finite element models of a structure in a more reliable way than the traditional ESO method. Additionally, the BESO method was successfully extended to Multiple Load Cases for both 2D and 3D. Two different algorithms were used to find the best structure experiencing more than one Load Case and the results of each are included.

optimal design of Multiple Load Case structures using an evolutionary procedure
Engineering Computations, 1994Co-Authors: Yi Min Xie, G P StevenAbstract:The structural optimization presented in this paper is based on an evolutionary procedure, developed recently, in which the low stressed part of a structure is removed from the structure step‐by‐step until an optimal design is obtained. Various tests have shown the effectiveness of this evolutionary procedure. The purpose of this paper is to present applications of such an evolutionary procedure to the optimal design of structures with Multiple Load Cases or with a traffic (moving) Load.
