中文摘要：
本文系统介绍了当前国际结构振动控制的公共平台——Benchmark模型，首次给出使用通用有限元软件ANSYS对第3阶段20层非线性钢框架抗震结构的有限元建模，结果表明，模态、无控地震反应分析结果和ASCE给出的MATLAB结果相同。利用粘滞阻尼器对此模型的耗能减振数值仿真分析的结果表明：粘滞阻尼器是一种性能很好的阻尼器，使用本文给出ANSYS的Benchmark有限元模型来进行耗能减振控制分析是方便的、可行的。
英文摘要：
Benchmark control problem is to provide a clear basis to evaluate the efficacy of various structural control strategies. In this paper, the 20-story steel frame of the nonlinear benchmark was selected as an analysis model. The finite element model about the same benchmark model was created using the ANSYS software. The model anal- ysis and the seismic nonlinear analysis of this benchmark model were done. In the end, the numerical results of the benchmark model controlled with liquid viscous damper indicate that the liquid viscous damper is a good dissipation device and the analysis of structural dissipation control using ANSYS is convenient.
