摘　　要：本文介绍了两种分析多点激励阻尼器连接建筑物响应的方法,比较了一致激励、大质量法和直接位移法计算结果。结果显示,大质量法和直接位移法求得的响应相近。一致地震激励作用下阻尼器耦合建筑物的响应,与受多点激励作用下处于中等硬度场地的耦合建筑物的响应相近。当耦合建筑物位于软土场地时或坚硬场地时,一致激励引起的响应与多点激励引起的响应差别较大。In this paper dynamic response of coupled buildings are computed by large mass method(LMM)and direct displacement method(DDM).Comparison are carried out between the response of coupled buildings under uniform excitation and under multi-excitation.It is found that response computed by LMM and DDM is close.The response of coupled buildings on medium stiff soil under multiple excitation is approximate to that of uniform excitation.The difference between the response of coupled buildings on soft or stiff soil and that of uniform excitation is large.
