Seismic Performance Evaluation Based on Static Loading Tests of Timber Frame Structures With Large Hanging Walls and Full Walls

Abstract eng:
In Japan, there are a lot of traditional timber buildings. In our investigation of the traditional timber houses, the structures which consist of tall hanging walls and beams called Sashigamoi in Japanese were found. Fig. 1 shows an example of the structures with large hanging walls in the historical timber houses. Timber frame structures with hanging walls are very important factor to think of seismic safety of timber buildings because the timber frames with hanging walls can lead to collapse of the whole buildings by breakage of the columns at the joints of the lower end of the hanging walls. The purpose of this study is demonstrative investigation of mechanical characteristics of timber frame structures with large hanging walls aiming for construction of a reasonable and practical seismic evaluation method. In this paper, we show the results of the static loading tests of the historical timber frames with large hanging walls, which have the walls at a part under the hanging walls. We examine the effect of the width of the walls and the number of the columns on the maximum restoring force and the deformation performance in the specimens. As a result, the following conclusions have been drawn. 1)
