人工中度地震试验后钢筋混凝土桥墩的抗余震性能

Residual Seismic Performance of Reinforced Concrete Bridge Piers After Artificial Moderate Earthquake Tests

通过中度人工地震试验,对试样的三个参数:横向约束、纵向钢筋互搭接头和加纤维增强聚合材料进行测试,并采用测量位移,弯曲和吸收能量的办法,对中度地震后的钢筋混凝土桥墩的抗震性能作出的评估。

The specimens were tested via artificial earthquakes for three parameters：confinement, lap-splice of longitudinal steel, and retrofitting fiber-reinforced polymer materials. The residual seismic performandce for the tested specimens was evaluated by measuring displacements , curvantures and energy absorption.
