摘要
北京朝阳医院钢楼梯结构属复杂空间异型结构。本工程中考虑楼梯踏步板及平台面板的蒙皮效应,成功解决了楼梯的抗侧刚度问题。同时,应用钢结构稳定理论解决了钢柱的计算长度取值问题,并用有限元方法验证了结构在初始缺陷及几何非线性影响下的整体稳定。
The steel stair structure of Chaoyang Hospital in Beijing belongs to complex allotype structure.In this project,the problem of resistance to lateral stiffness is successfully solved through considering with shear-resistant membrane of flier and platform.Otherwise,the effective length of the steel column is derived,and the integer buckle stabilization of the structure considering construction defect and geometric nonlinearity is validated.
