| Research Abstract |
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.
