［摘要］目前對復(fù)雜形狀樓板主要通過考慮彈性板來分析設(shè)計，工程設(shè)計中少有考慮樓板剛度折減對整體結(jié)構(gòu)分析的影響。以一復(fù)雜結(jié)構(gòu)工程為實例，考慮不同樓板剛度對結(jié)構(gòu)進行對比分析，揭示了樓板剛度對結(jié)構(gòu)整體受力性能的影響。另外對局部樓板進行了非線性有限元分析，通過對比整體結(jié)構(gòu)樓板應(yīng)力分析結(jié)果，建立確定樓板剛度折減的方法。

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
