【提要】 對一個大比例低配筋圓端型橋墩模型進行了擬動力試驗研究，獲得了該橋墩在實際地震波作用下的地震反應(yīng)及破壞形式，對該橋墩的抗震性能進行了分析，得到了該橋墩能夠承受的實際地震動水平，對其抗震能力進行了評估；同時得到了其滯回曲線，為低配筋橋墩的抗震設(shè)計、評估與加固提供了依據(jù)。
【關(guān)鍵詞】 抗震 擬動力試驗 橋墩
Study on Seismic Performance of Roundended Piers by Pseudo Dynamic Test /Ju Yanzhong1, Yan Guiping2, Huang Xuanye2(1 School of Civil Engineering, Northeast China Institute of Electric Power Engineering,Jilin 132012,China; 2 School of Civil Engineering and Architecture, Beijng Jiaotong University，Beijing 100044,China)
Abstract:A large scale roundended pier model with low ratio of reinforcement is made, and the seismic performance of pier model is studied by pseudo dynamic test. The seismic responds and hysteretic curve of pier acted by real earthquake wave are gained.The seismic performance of pier model is analyzed and  the enduring actua l level of earthquake is given.
Keywords:seismic;  pseudo dynamic test;  piers
