[摘要] 楼梯是重要的紧急逃生竖向通道，它的完整性对人员的安全异常重要。然而在汶川地震中，砌体结构的楼梯构件破坏较为严重。通过汶川震害分析，提出楼梯构件的具体计算方法和相应的抗震构造措施，以期望能有效地解决楼梯构件在地震中的安全问题，为以后的结构和楼梯设计提供借鉴。

Abstract: Stairs is the important access to escape, its integrality is very important to people's safety, but many masonry structure stairs in Wenchuan Earthquake were seriously destroyed. By the analysis of the Wenchuan Earthquake, calculating methods and details of seisnuc design can be induced to the stairs member, it can help to promote the safety of stairs member in earthquake as well as be the sample of the coming structure and stairs design.
