‘NON LINEAR STATIC ANALYSIS OF TYPICAL SHORT AND MEDIUM SPAN BRIDGES IN URBAN AREA’

Abstract

Non-linear static analysis is an effective analysis tool to evaluate the performance behavior using inelastic seismic study of Building and Bridges. Pushover technique uses non-linear static procedure where displacement control approach by capacity spectrum method and has been studied over the typical bridges in urban areas. For studying the performance behavior of bridges in urban area under high seismicity, without mentioning specific route typical structures resembling Metro piers i.e. mono-piers, multi bent structures like flyover and short span bridges have been studied. The seismic region of greater impact i.e seismic zone IV and V have been considered. Soil-structure interaction (SSI) has also been considered. Linear static (response spectrum) as well as nonlinear static procedure like push over analysis with parametric variation have been studied to understand their seismic performance. The evaluation of mode of failure in terms of hinge formation in structural compo...
