Dynamic Response Analysis of Two Different Cable-Stayed Bridge Using Blast Load

Abstract

This study focused on the dynamic response and progressive collapse behavior of cable-stayed bridges subjected to blast load on H-type pylon with different cable arrangements (fan, radial). Using advanced computational simulations, this study aims to provide insights for optimizing bridge designs and enhancing resilience against blast-induced effects. This study utilizes ETAB, FEM analysis to assess the time period and frequency behavior of fan and radial type cable arrangements in cable-stayed bridges, displacement and drift of structural member subjected to blast loading conditions. The study underscores the structural efficacy of specific cable arrangements, identifying the FAN arrangement with an H-type pylon exhibits better resistance against blast loading.
