Analysis of Bridge Earthquake Damage and Reasonable Aseismic Systems

Abstract:

Damage to simple beam bridge, continuous beam bridge, continuous rigid frame bridge and arch bridge is analyzed in Wenchuan, Tangshan and Yunnan earthquakes etc. The results show that seismic damage for the same bridge system has many common features, and seismic performance of different bridge system varies greatly. Fall, bearing sliding, beam displacement and collision between adjacent beams at expansion joints the is major earthquake damage for simply beam bridge. Seismic damage ratio and degree of continuous beam bridge is bigger than the simple support beam bridge. Earthquake damage of the continuous rigid frame bridge is obvious lightly in the close simple beam and continuous beam bridge. Seismic damage of arch bridge is more complex. Selection methods of reasonable aseismic system for the straight line bridge in seismic zone are proposed based on the analysis of earthquake damage and numerical analysis.
