A direct displacement-based seismic design procedure of RC bridge piers fulfilling multiple performance objectives,which usually require that the structure can sustain a minor earthquake without any damage,a moderate earthquake with repairable structural damage,and a strong earthquake without collapsing,is developed by means of the improved capacity spectrum method.
通过改进能力谱法,给出了一个可以实现“小震不坏、中震可修和大震不倒”多级性能目标的钢筋混凝土桥墩直接基于位移的抗震设计方法。
