A study on constructing factors of three-storied wooden housings in the built-up area

Abstract

Three-storied wooden housings has been increasing in the built-up areas after the amendment of building codes imposed on them.The vulnerability of urban area with these housings under an earthquake has to be known for disaster mitigation planning purposes.This study aims to clarify factors which explain the reasons why these type of housings are constructing in the built-up area.Consequently,the three-storied wooden housings are built to accommodate big families on a dwelling unit,which built on small lot areas.If the characteristics of the area are considered,families who had enough budgets for reconstruction and who moved in after the Great Hanshin-Awaji Earthquake built three-storied wooden housings.
