摘要
基于SAP2000建立常规错层结构和新型带钢管混凝土柱错层结构的有限元模型,并改变错层高度和钢管混凝土柱的截面尺寸两个参数。进行动力弹塑性时程分析,得出位移、位移角、基底剪力以及塑性铰出现的顺序和分布情况,对比各个错层结构模型的抗震承载能力的优劣,对错层结构抗震设计提供有效的参考方案。
Based on SAP2000, the finite element models were established for conventional staggered floor structure and new split-level structure with concrete-filled steel tubular columns, with the two parameters of split-level height and the sectional size of concrete-filled steel tubular columns changed. Through dynamic elastoplastic time-history analysis, the sequence and distribution of displacement, displacement angle, base shear and plastic hinge are derived, and based on the comparison of the seismic bearing capacity of the staggered floor structural models, effective references can be provided for the aseismic design of the staggered floor structure.
