Numerical analysis for shaking table tests of wooden houses considering constraint of deformation by exterior mortar walls

Abstract

By the recent researches of the shaking table tests of wooden post-and-beam houses, the effect to the seismic performance by exterior walls was not negligible. In this paper, the new numerical analysis model for exterior walls like mortar walls in Japanese post-and-beam wooden houses was suggested and the reproductive numerical analyses of the shaking table tests conducted at E-defense (NIED, Miki-city, Japan) were executed to estimate the effect to the seismic performance by exterior walls. By the time history response analyses of shaking table tests for two-story wooden houses, it was found that the multi-story effects and size effect of the mortar walls were realized by our modeling method.
