STRUCTURAL COLLAPSE OF CONCRETE BRIDGE AND ITS RESULTANT EFFECTS. (KEY IJP************775)
This document provides a comprehensive analysis of bridge failure and its associated direct and indirect consequences statistics. The analysis is based on an extensive literature review and information obtained from various websites, with a particular emphasis on RCC, PSC, and steel composite bridges. Failures have been categorized into two types: complete collapse of the bridge and partial collapse that leads to loss of serviceability. The process of categorizing prevalent causes of failure and failure modes is being carried out. The findings on bridge failures reveal that collapses arising from natural hazards, design flaws, and insufficient knowledge are the most frequently observed in bridges, followed by incidents and human fallibility. Upon chronological analysis, the data exhibits a declining pattern in collapses caused by inadequate knowledge and a rising trend in failures caused by accidents and natural calamities. The results derived from the analysis of bridge failures are of significant value, as they furnish a vast repository of information for civil engineers to augment their understanding of the factors contributing to such failures. Through the analysis and assessment of the structural deficiencies of these bridges, future errors can be prevented by leveraging historical knowledge. Statistical analysis can assist in identifying the potential impact of significant hazards on bridge structures and aid in developing plans to mitigate their consequences. Fatigue failures are the primary mode of failure observed in steel bridges under non-collapse conditions. The manuscript culminates with an analysis of the implications of bridge collapse and their importance in evaluating the risk of bridge constructions.
