在地震发生时,楼梯对人们逃生起着至关重要的作用。但从震后的灾害情况看,在混凝土框架结构中常会发生楼梯间构件被破坏的情况,甚至出现楼梯间整体倒塌的现象,丧失了应有的疏散功能。针对混凝土框架结构不同楼梯的构造方案进行了抗震性能分析,明确了混凝土框架结构楼梯的合理构造方案,为结构设计提供可靠的依据。
When the earthquake occurred, the stairs played a crucial role in people’s escape. However, from the disastrous situation after the earthquake, it often happens that the components of the staircase are damaged in the concrete frame structure, even the whole staircase collapses, and the necessary evacuation function is lost. According to the seismic performance analysis of different staircase structures of concrete frame structure, the rational construction plan of concrete frame structure staircase is clarified, which provides a reliable basis for structural design.
