Bridge Engineering – Classification of Bridges

components of bridge

Bridge Engineering – Components of Bridge Structures A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. The obstacle to be crossed may be a river, a road, railway or a valley.  Classification of … Read more

Inelastic Seismic Response of Structures

Non linear dynamic analysis

Inelastic Seismic Response of Structures Under relatively  strong  earthquakes, structures undergo inelastic  deformation  due to  current seismic design philosophy. Therefore, structures should have sufficient ductility  to deform beyond the yield limit.  For understanding the ductility demand imposed by the  earthquake,  a  study  of  an  SDOF system  in inelastic range is of great help. The  inelastic  … Read more
