NUMERICAL ANALYSIS FOR EVALUATION OF THE EFFECT OF EXTERIOR WALLS ON SEISMIC PERFORMANCE OF WOODEN POST-AND-BEAM HOUSES

摘要

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 by using linked panel elements. By the numerical analysis of shaking table tests conducted at E-defence (NIED, Miki-city, Japan) on 2005, it was found that the multi-story effects and size effect of the mortar walls were realized by our modelling method.
