Influence of earthquake angle on seismic performance of concrete highway bridges
Stjepan Lakusic
Abstract:This study aims to evaluate the effect of earthquake angle on the seismic performance of a concrete highway bridge. As a numerical example, a twin prestressed concrete box-girder highway bridge was analysed using finite element methods. The bridge was subjected to the 1992 Erzincan earthquake ground accelerations in 19 directions with values ranging from 0° to 90° in 5-degree increments. To evaluate the effects of different earthquake angles on seismic performance, variations in the maximum displacements, inte… Show more
