Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...

Buckling restrained braces (BRBs) have a similar behavior under compression and tension loadings. Therefore, they can be applied as a favorable lateral load resisting system for structures. In the performance-based earthquake engineering (PBEE) framework, an intermediate variable called intensity measure (IM) links the seismic hazard analysis with the structural response analyses. An optimal IM...

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 ...

A steel frame with a semi-rigid connection is one of the most widely used structural systems in modern construction. These are cheap to make, require less time construct and offer highest quality reliable construction without need for highly skilled workers. However, these show greater natural periods compared their perfectly rigid counterparts. This causes building attract low loads during ear...

This paper provides insight into a probabilistic demand analysis of steel-concrete structures equipped with novel dissipative components. DISSIPABLE components were studied in the framework European Research Fund for Coal and Steel (RFCS) project, funded to test large-scale which dissipation is concentrated specifically designed elements that act like fuse can easily be replaced after seismic e...
