Abstract Owning to good mechanical properties, steel–concrete composite (SCC) and prestressed concrete (PC) box girders are the types of elevated structures used most in urban rail transit. However, their vibro-acoustic differences yet be explored depth, while structure-radiated noise is becoming a main concern noise-sensitive environments. In this work, numerical simulation investigate vibrati...

Infrastructure development is the very important for any Country. Highway’s infrastructure comprises two part say Roads and Bridges, supplementary to each other. In modern projects of structures increased about 40% 50% which have big influence complete project within targeted span period. As per site condition aesthetic requirement, there are several types bridges. Bridges different type supers...

This case study aimed to compare the differences in durability and prestress loss between normal-weight-concrete (NC) lightweight-aggregate-concrete (LWC) prestressed box girders, which were constructed at same time area, so as verify superiority of using synthetic lightweight aggregate (LWA) made from reservoir sediments bridges. For NCs LWCs used basic mechanical properties (compressive stren...

An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of constant moment in the elastic range of structural response. The results of the experiments were compared with an elastic complex semi-analytical finite strip method of analysis, ...
