摘要
利用有限元分析软件ANSYS对平齐端板半刚性组合节点进行有限元计算分析,结果与试验数据吻合,论证了数值模拟的有效性,分析了组合节点中纵向钢筋总面积及混凝土板厚度对组合节点初始转动刚度和抗弯极限承载力的影响,从而为这种节点的设计和应用提供了数值模拟的参考方法。
Calculations of semi-rigid composite joints with flush end - plate are carried out with a FE-program ANSYS. This method is demonstrated by comparing the numerical result with the experimental investigations. The influences of the total area of longitudinal reinforcement and the thickness of concrete slab on the initial rotation stiffness and the ultimate moment capacity are researched. Therefore, it provides the numerical modeling method for the design and application of the composite nodes.
