The performance of girder bridges in the Wenchuan Earthquake and a new method for seismic protection
This paper reports some typical damage samples of the girder bridge in the Wenchuan earthquake, based on an inspection visit to the earthquake site. The causes and regular patterns of the earthquake damage are analyzed.Meanwhile, a new method for seismic protection in strong seismic excitation is proposed. To avoid earthquake damage, the new method uses proper constructional measure to change the transmission of earthquake energy,reduce the relative displacement between superstructure and substructure, and assure the safety of substructure.
