Dynamic response of prestressed segmental composite concrete bridges

Abstract

In the past few years, we faced several under-construction failures of the prestressed concrete segmental bridges. The failures were also encountered during the erection of the span using the launching girder. It is also observed that most of the structures were analyzed and designed using the conventional method like linear static analysis using STAAD PRO software. The linear static analysis doesn’t often justify the actual performance of the structure leading toward the collapse when undergoing huge in-elastic deformation over time. The Non-Linear dynamic analysis provides more mathematical accuracy by using a simulation-based finite element-based tool. In order to overcome such failures in near future, a deep core and distinct type of analysis need to be carried out. The vision of the present study is to review the non-linear dynamic analysis of the precast segmental bilateral post-tensioned spine and wing-type superstructure bridge. There is no specific or distinct recommended approach for how one can to evaluate the natural fundamental frequencies simply by problem formulation and calculations, and there is no restricted formation that allows the structural entities by false passive designs in contrast to a consistent end-to-end load, therefore, uneven learning delivers undeveloped dynamic data (i.e. fundamental frequencies) of structures.
