中文摘要：
本文首先介绍了一幢安装了粘滞阻尼器的复杂体型高层方钢管混凝土框架结构的1／15缩尺模型的模拟地震振动台试验结果；在此基础上，建立了梁、柱构件的多弹簧模型并组建了整体结构的计算分析模型，运用此计算模型首先对试验模型结构进行了动力弹塑性时程分析，计算结果和试验结果吻合较好，验证了计算模型的正确性；最后，以同样方法对原型结构进行了计算分析，并结合试验结果研究探讨了此结构的抗震性能和阻尼器的消能减震效果。结果表明：该结构未出现明显的薄弱层，能够满足规范的抗震设防要求，阻尼器发挥了一定的消能减震效果，进一步提高了结构的抗震性能。
英文摘要：
Firstly, the shaking table test results of a 1/15 scale model of concrete filled square steel tubular frame structure with viscous dampers is introduced. Secondly, the structural analysis model composed of multi-spring model of beams and columns is established, then the elasto-plastic time-history analysis for the shaking table test model of the structure is carried out, and the analysis results are in agreement with the test results. Finally, the analysis for prototype structure is performed by the same procedure. The analysis and test results show that the structure has no obvious weak story and can meet the code requirements for energy dissipation structures, and the dampers play an important role in energy dissipation and improve the seismic performance of the structure further.
