摘要
梯板平面内横梯方向的刚度及横梯方向的地震分量对楼梯的受力、安全都有着一定的影响,在耐震楼梯设计中应采取相应对策。本文提出钢筋混凝土楼梯结构设计意见,给出若干新的构件连接节点大样,并进行分析和比较。
There must be some influence on the inner force and the safety of stairs due to the cross plan rigidity of stairs slab and cross component of earthquake,some corresponding resolving method should be adopted in the shock-bearing design.for the reinforced concrete stairs,some ideas of structural design are put forward,and some new joint details are given,the analyses and comparisons for them are made.
