 [摘要] 基于大型通用有限元软件ABAQUS对一栋20层的框架核心筒结构的不同楼板模型进行了罕遇地震下的弹塑性时程分析，并对比不同楼板模型对弹塑性时程分析的影响。具体过程为：在结构设计软件YJK中进行设计和配筋，确保各项指标符合规范要求。然后将包括配筋的结构模型转入ABAQUS中，其中楼板分别按刚性楼板、弹性楼板、弹塑性楼板进行转换。并考虑了结构的几何非线性和材料非线性，材料本构均按照规范要求输入，混凝土梁元采用基于规范要求编写的Vumat。在验证模型转换正确后进行弹塑性时程分析，并从基底剪力、楼层剪力、层间位移角、节点位移、破坏发展状态以及计算耗时等方面对比了三个模型间的差异，为结构在ABAQUS中进行弹塑性时程分析提供参考意见。

Abstract: Through elasto-plastic time history analysis under the rare earthquake for a block of 20 layers of frame coretube structure under different slab model based on the large universal finite element software ABAQUS, Comparing with different floor model's influence on the elastoplastic time history analysis. For the specific process:  Designing and reinforcementing in the structural design software YJK, ensure that the indicators meet the code requirements. Then transform the model which is included reinforcement into ABAQUS, it including rigid floor, elastic and elastic-plastic floor and considering the structure geometric nonlinearity and material nonlinearity, The material constitutive are accordance with the code requirements and concrete beam adopt Vumat edited based on the requirement of code. Proceeding elastoplastic time history analysis after the verification of model transformation is correct, Comparing the differences between the three models from the base shear, floor shear, interlayer displacement angle, node displacement and state of damage development and computing time ,provides some guidance in engineering of the elastic-plastic time history analysis for the structure in ABAQUS.
