摘　　要：对顶层有悬挂体的结构进行了分析,提出了以结构底部剪力最小为目标函数,采用复形法对顶层悬挂结构的参数进行优化的方法,编制了适用性较好的计算机程序,并以一个7层钢筋混凝土框架为算例,得到了一些有用的结论,可供参考。The structure with a suspended mass on the top floor is analyzed in this paper. Also the complex method of taking minimum bottom shear as the objective function has been used to optimize the parameters of top - floor suspended structure and to work out a computer programme of good adaptability. Some useful conclusions are made on the basis of a demonstrative example of 7 - story reinforced concrete frame and can be shared by others.

关 键 词：顶层悬挂结构 地震作用 复形法 参数优化
