压型钢板—混凝土组合板两材料之间的接触和相关力学性能较为复杂。为了表明一种闭口型压型钢板—混凝土组合板的承载性能,采用非线性有限元分析软件ABAQUS对混凝土强度、压型钢板屈服强度、纵向剪切强度给予整体承载性能的影响进行了参数分析。并建议采用简化纵向剪切强度—水平滑移关系的有限元建模方法,而其计算结果与力平衡法而得到的有限元分析结果和欧洲规范4设计计算结果进行了对比。结果表明,对组合板的承载性能给予最大影响的因素之一为纵向剪切强度。并且建议的修正有限元模型结果具有良好的准确性。
The contact between steel plate and concrete composite plate and the related mechanical properties are more complicated. In order to show the bearing capacity of a closed profiled steel plate-concrete composite plate, parametric analysis was conducted using the ABAQUS nonlinear finite element software to analyze the effect of concrete strength, yield strength and longitudinal shear strength on the overall bearing capacity. The finite element method to simplify the relation between the longitudinal shear strength and the horizontal slip is proposed. The results of the calculation are compared with the results of the finite element analysis obtained by the force balance method and the results of the European standard 4. The results show that one of the factors that has the most influence on the bearing capacity of composite board is the longitudinal shear strength. And the proposed modified finite element model has good accuracy.
