［摘要］目前对复杂形状楼板主要通过考虑弹性板来分析设计，工程设计中少有考虑楼板刚度折减对整体结构分析的影响。以一复杂结构工程为实例，考虑不同楼板刚度对结构进行对比分析，揭示了楼板刚度对结构整体受力性能的影响。另外对局部楼板进行了非线性有限元分析，通过对比整体结构楼板应力分析结果，建立确定楼板刚度折减的方法。

Abstract： Currently the analysis of complex shape slab is mainly considered to be elastic. Stiffness reduction of slab is rarely considered in the analysis of structural analysis. Taking a complex structure of the project as an example, the influence of slab-stiffness on the mechanical performance the whole structure was revealed. In addition, partial slab was studied by nonlinear finite element analysis. A method to determine the stiffness reduction of slab was established through by comparing the results of the stress analysis on whole structure slab.

Keywords: slab-stiffness; stiffness reduction; nonlinear finite element analysis
