This study aimed to obtain quantitative understanding of the seismic performance provided by the staircase which a wooden building with two or more stories always has, through static lateral loading tests and numerical analysis based on structural dynamics models. A total of four buildings by two construction methods; post-and-beam and light-frame, and with two types of staircases; U-shape winding staircase and straight flight staircase, were used as specimens. The test results revealed that the seismic performance of the staircases resulted from the fact that the sideboards incidentally serve as non-buckling braces combined with the treads. This demonstrates how the fasteners joining the timber frame and sideboards are of crucial importance.

本研究旨在通过静力水平加载试验和基于结构动力学模型的数值分析，定量了解两层或多层木结构建筑中楼梯的抗震性能。共四栋建筑，采用两种施工方法：柱梁和轻型框架，并有两种类型的楼梯：U形旋转楼梯和直飞行楼梯，被用作标本。试验结果表明，楼梯的抗震性能是由于边板与踏板一起起到了非屈曲支撑的作用。这说明了连接木框架和餐具柜的紧固件是如何至关重要的。
