Structural health monitoring system of Ironton-Russell bridge during Substructure Construction
Proceedings of SPIE, 2016Co-Authors: Aditi Dalvi, Mehdi Norouzi, Victor J. Hunt, Arthur J. HelmickiAbstract:Monitoring a complex structure has gained popularity worldwide to ensure safety and longevity of the structure. Structural Health Monitoring (SHM) systems have been employed for highway bridges to increase the effectiveness of their in-service inspection, to help measure its degradation or damage, and hence, to ensure it’s safe and reliable operation. SHM may also be employed during the Construction of a structure in order to ensure the safety and performance of the Construction process. Monitoring during Construction can also help designers compare the actual behavior of a structure with design models especially because of increasing development of accelerated or otherwise novel Construction techniques. Analyzing the behavior of a structure at different stages of Construction may also help later define some of the abnormal responses during the lifespan of a bridge. This paper overviews the SHM system of the Ironton-Russell Bridge, Ohio at the Construction stage of its Substructure. The stages involved in monitoring such as instrumentation of sensors, acquiring data from the sensors, data processing that includes a warning system, static analysis of the data collected and website are detailed in this paper. In addition to this, the effect of Construction events as observed by the sensor data for the Substructure is analyzed in detail thus validating the capability of the monitoring system. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

Structural Health Monitoring System for Ironton–Russell Bridge, Ohio and Kentucky: Phase 1. Substructure Construction
Transportation Research Record, 2015Co-Authors: Fan Zhang, Mehdi Norouzi, Victor J. Hunt, Arthur J. HelmickiAbstract:The monitoring of bridge structures during Construction has received significant attention in recent years as accelerated Construction techniques are being used more frequently. Continuous monitoring systems can verify that quality and safety are maintained during Construction by minimizing Construction uncertainties and aiding designers to compare the actual behavior of a structure with the design models. Additionally, the behavior of structures in different stages of Construction may be important in the definition of abnormal responses (e.g., the loss or reverse of a previously measured dead load) during the life span of a bridge. This paper gives an overview of the monitoring system for Substructure Construction that was considered for the Ironton–Russell Bridge between Ironton, Ohio, and Russell, Kentucky, during its design and service stages. First, the sensory network of the bridge will be detailed. Second, data processing (which involves two anomaly detection algorithms) and other components of the...

Geodetic Accuracy in Observational Construction of an Excavation Stabilized by Top-Down Method: A Case Study
Geotechnical and Geological Engineering, 2019Co-Authors: E. Ghorbani, M. KhodaparastAbstract:Traffic disorder and excavation hazards due to Substructure Construction are of the foremost challenges in great cities. Deep excavation causes stress changes in adjacent soil mass near the excavated site which induces ground deformations. Magnitude of this deformation depends on many factors including excavation geometry, ground conditions, supporting system, Construction quality, time interval of execution, and Construction delays. Field monitoring utilizing appropriate instruments allows conductor to predict the ground deformation trends and is useful in risk management and improvement of Construction stages. It is important to measure the accuracy of the selected monitoring tool in the field precisely. In this study, accuracy of monitoring tool and observational Construction of a deep excavation in an overcrowded street are discussed. In observational Construction method, Construction sequences are monitored and the obtained data are analyzed frequently, so Construction stages or designed elements of the structure can be modified to increase safety or to enhance the economy of the project. In this article, ground deformation trends in an excavation supported by Top-Down method in the city of Qom, in Iran is surveyed by means of Total Station TS02 and the precision of the gathered information is evaluated using statistical analysis and numerical model. On this basis modifications are applied and Construction stages of southern side of the excavated area are reconsidered to cease the increasing failure in this side.
