Abstract The masonry bridges on the Kalka Shimla Mountain Railway line, which have multiple arch galleries in form of Roman aqueducts, are spectacular. line is situated severe seismic zones (Indian Standard 1893:2016). This research assesses vulnerability Bridge No. 541 line. bridge tallest route. In particular, it using finite element (FE) analysis. For this purpose, an FE model for developed ...

Nanjing Dashengguan Bridge, which serves as the shared corridor crossing Yangtze River for both Beijing-Shanghai high-speed railway and Shanghai-Wuhan-Chengdu railway, is the first 6-track high-speed railway bridge with the longest span throughout the world. In order to ensure safety and detect the performance deterioration during the long-time service of the bridge, a Structural Health Monitor...

Gap between the steel tube and core concrete of Concrete-Filled Steel Tube (CFST) members is regarded as an initial imperfection, which may exist in CFST arch bridge due to construction process problems. In this paper, based on design scheme bolt-welded joints rib columns extra-long span bridge, effects two types imperfections, interfacial gap spherical-cap gap, mechanical properties Bolt-Welde...

Abstract This work was aimed at analysing the redundancy of hangers a steel arch bridge and resilient behaviour bridges when subjected to blast loading. Firstly, numerical models were created perform linear static analysis. Then, structure statically verified according Eurocode norms. Afterwards, analysis conducted by considering failure cases in symmetric asymmetric configurations. In each cas...
