Wind and Seismic Response Analysis of Cable-Stayed Bridge—A Case Study
摘要
Cable-stayed structures represent the most recent and rapidly evolving advancements in bridge systems. A cable-stayed bridge is characterized by its deck being supported by cables affixed to towers, offering a larger span and aesthetic appeal. Of utmost importance is ensuring that these bridges will remain structurally sound and safe in a range of environmental circumstances. This case includes the study of the dynamic performance and response of the Pandit Deendayal Upadhyay cable-stayed bridge in Surat, Gujarat, concerning wind and seismic loads. The geometry of the bridge is modeled in the study, and its performance under wind and seismic pressures is examined using STAAD Pro tool, a widely used structural analysis and design tool. The study involves the creation of an accurate model that incorporates cable elements. Wind load study methodically addresses the complications between the bridge’s structural components and the flow of wind. Similar to this, response spectra are included, the structure-soil interaction is considered, and the analysis corresponds to the features of the area. Through this analysis, stability of the bridge, its deflections, and internal forces across a spectrum of wind speeds and seismic intensities have been studied. Finally, utilizing STAAD Pro tool, the wind and seismic response analysis of the Pandit Deendayal Upadhyay cable-stayed bridge provides vital insights into the dynamic behavior of cable-stayed bridges and their reaction to critical loading scenarios. The study focuses the importance of comprehensive analysis and design methodologies in assuring the safety and functionality of modern bridge constructions, particularly in seismically active areas such as Gujarat.
