摘　　要：包头市一高层住宅楼其主体结构采用钢管混凝土束结构,但由于此类结构属于新型结构,无法使用常规的计算分析程序计算其大震安全性,故采用SAUSAGE软件进行动力弹塑性时程分析,并根据结构的特殊性,重新拟定了材料的本构关系。分析结果表明,本结构体系满足抗震设防目标和规范要求,为同类结构的抗震分析提供了参考和建议。The main structure of a high-rise residential building in Baotou adopts the concrete-filled steel tube structure. However, because this type of structure is a new type of structure, the conventional calculation and analysis programs cannot be used to calculate the safety of large earthquakes, so the software SAUSAGE is used for dynamic elasto-plastic time history analysis. And according to the particularity of the structure, the constitutive relationship of the material is re-drawn. The analysis results show that the structural system meets the seismic fortification objectives and code requirements. It also provides references and suggestions for seismic analysis of similar structures.

关 键 词：钢管混凝土束结构 SAUSAGE 弹塑性时程分析 抗震性能
