摘　　要：为研究不同构造类型的叠合板受力性能,采用有限元软件建立了不同工况下的简支叠合板非线性有限元模型,分析了不同构造方式下叠合板的破坏形态、开裂荷载、挠度变化等特性。结果显示,外附工具均能显著提高叠合板的受力性能,尤其是板底外附钢管相较于无外附工具的叠合板受力性能可提高约1倍;板厚越大,其与外附工具的配合也越好,对于板的受力性能提高效果也越好。In order to study the mechanical properties of composite plates of different structural types,nonlinear finite element models of simply supported composite plates under different working conditions were established by using finite element software.The failure forms,cracking loads and deflection changes of composite plates were investigated.The results show that the mechanical properties of the composite plates can be significantly improved by the external tools,especially the mechanical properties of the steel tubes attached to the bottom of the plates can be increased by about twice compared with the composite plates without external tools.The thicker the plate,the better the fit with the external tool,and the better the effect of improving the mechanical performance of the plate.
