在 ELSA 实验室对现有矩形空心截面桥墩的两个大型模型进行了循环试验。原型结构是一座 1975 年在奥地利建造的现有钢筋混凝土公路桥。桥墩存在一些抗震缺陷，因此表现出较差的迟滞性能和有限的变形能力以及不良的破坏模式，不符合现代抗震结构规范的要求。将实验数据与数值和经验预测进行比较。版权所有 © 2003 约翰·威利父子有限公司
Cyclic tests on two large‐scale models of existing bridge piers with rectangular hollow cross‐section were performed in the ELSA laboratory. The prototype structure is an existing reinforced concrete highway bridge constructed in Austria in 1975. The piers presented several seismic deficiencies and consequently they showed poor hysteretic behaviour and limited deformation capacity as well as undesirable failure modes that do not comply with the requirements of modern codes for seismic‐resistant structures. Experimental data are compared to numerical and empirical predictions. Copyright © 2003 John Wiley & Sons, Ltd.
