基于规范的楼梯抗震设计探讨

Discussion on Seismic Design of Stairs Based on Specifications

文中总结了基于规范的常规楼梯抗震设计方法,并针对常规楼梯设计方法中存在的梯柱截面不按框架柱进行设计的问题,给出了三个具体的解决办法,(1)在设计初期提前与审图单位进行技术沟通,确定楼梯设计方法。(2)梯柱截面尺寸严格按规范执行。(3)采用滑动支座或装配式楼梯。

The article summarizes the conventional seismic design methods for stairs based on specifications,and provides three specific solutions to the problem of not designing the section of the ladder column according to the frame column in the conventional staircase design methods.(1)In the early stage of design,technical communication is conducted with the reviewing unit to determine the staircase design method.(2)The cross-sectional dimensions of the ladder columns shall be strictly executed in accordance with the specifications.(3)Use sliding supports or prefabricated stairs.
