摘要

针对工程中应用广泛的门式刚架轻型房屋钢结构,给出节点初始刚度的计算公式,运用ANSYS分析了端板连接处的刚度,对影响其刚度的几种要素进行分类讨论,并讨论节点刚度对结构整体弯矩分布的影响。
The bolted end-plate connections in steel portal frames is one of the most commonly used connection type in light steel structures.The computing formulae of initial stiffness of connections is given.Based on the software ANSYS,connection stiffness is analysed.Discussion among several factors influencing the stiffness is proposed.The influence of connection stiffness to moment distribution is considered.
