摘　　要：以沪江大学砖木结构优秀历史保护建筑物为研究对象,通过对两组不同粘结材料制作的墙体构件进行低周反复荷载试验,结合该建筑物现场检测数据,分析墙体的滞回特性、延性、耗能能力等抗震性能,并对其进行了客观的评价。试验中,试件材料和施工工艺完全依照原结构,并模拟实际荷载。结果表明,该建筑物墙体的各项指标均达到甚至略高于现行规范的要求,具有良好的抵抗水平荷载作用的能力。Taking individual excellent historical preserved buildings with brick structure in University of Shanghai as objects,and based on the data of low cyclic loading test for two groups of testing brick walls as well as the scene test results of the building,the hysteretic trait,the ductility and the behavior of energy dissipation were analyzed,and an objective evaluation was given to brick structural seismic performance of historical preserved buildings.During the test,the structural material and construct technology according to the primary building and imitational vertical stress were obtained.The test result shows that the resistant capacity of the structure can meet the request of related criterion,and represent superior performance of resisting horizontal load.
