摘　　要：为便于建立用于闭口型压型钢板-混凝土组合楼板振动问题分析的有限元模型,以位移等效和刚度等效为原则,分别建立闭口型压型钢板-混凝土组合楼板的各向同性等效计算模型和正交异性等效计算模型,并通过三维有限元模型和楼板振动试验进行比较分析,以得到针对其振动研究的闭口型压型钢板-混凝土组合楼板的等效简化计算模型。研究发现:采用闭口型压型钢板-混凝土组合楼板的各向同性等效计算模型和正交异性等效计算模型均可得到有效的结果,正交异性等效计算模型相对于各向同性等效计算模型求解精度更高;采用等效计算模型使模型建立更快捷,且能显著提高计算效率。The finite element model for vibration analysis of closed profiled steel sheet concrete composite floor(CPSSCCF) is established.Based on the principle of displacement equivalence and stiffness equivalence,isotropic equivalent calculation model and orthotropic equivalent calculation model of the CPSSCCF are established respectively.The results are analyzed and compared with those of pure three-dimensional finite element analysis and floor vibration test.The equivalent simplified calculation model of the CPSSCCF is obtained and verified.It is found that using the isotropic equivalent calculation model and the orthotropic equivalent calculation model of the CPSSCCF can obtain effective results,and the solution accuracy of the orthotropic equivalent calculation model is higher than that of the isotropic equivalent calculation model.Using the equivalent calculation model can establish the model more quickly,and can significantly improve the calculation efficiency.
