关于装配式混凝土楼梯的设计及节点分析

Design and node analysis of assembled concrete stairs

从装配式建筑项目设计中,总结装配式混凝土楼梯设计常见误区,并给出合理计算方法。对设计中易被忽视的楼梯间外墙稳定性问题提出保证措施。通过变形分析指出传统装配式混凝土楼梯连接方式(一端固定铰支座、一端滑动铰支座)的弊端,提出创新的装配式混凝土楼梯连接节点,并分析其合理性。

The common mistakes of assembled concrete stair design were summarized and a reasonable calculation method was given.The measures to guarantee the stability of the exterior wall of the staircase are proposed.Through the deformation analysis,it points out the disadvantages of the traditional connecting mode(one end of fixed hinged support,one end sliding hinge support)of the precast concrete stairs,and puts forward an innovative connecting node,and analyzes its rationality.
