比例ハザードモデルを用いた戸建住宅の外壁改修周期の推定

摘要

The purpose of this research is to clarify the specification and evaluation of a factor which affects presumption of an exterior wall refurbishment cycle by using a proportional hazard model. Covariates affecting exterior wall refurbishment were "Lath-mortar" and an "Area". A Congested area of wooden built-up area has a long refurbishment cycle, and lath-mortar tends to shorten a refurbishment cycle. Moreover, an exterior wall refurbishment cycle will tend to become short if the number of times of repair increases, and it became clear that there is no difference of the refurbishment cycle by a construction age.%総務省統計局の住宅・土地統計調査によると、東京都には2003 年の時点で600万棟を超える住宅ストックが存在している。巨大地 震に対する脆弱性や、設備・規模などが現在の社会的要求に適合し ていないなど、これらの住宅ストックの中には改善を求められてい るものが数多く存在している。
