- Abstract
Residual displacement between girders would have occurred after the main shock. And it would get further destroy (like pounding and unseating) with the excitation of aftershocks. Conclusions draw from the comparation on the response of continuous bridge with or without Cable-sliding expansion joints (CMEJs) under the excitation of seismic sequence. Relative displacement between girders gets effective restrained during the whole seismic process with the CMEJs which get great meaning for avoiding pounding and unseating. With the contribution of the CMEJs, all the girders work together causing the relative displacement between girder and the pile decreased. And the pier force also gets optimized.
