| Abstract |
In spite of the recent rapid increase in high-rise residential building, minimal research has been carried out that focuses on the consequences of such a rapid increase, such as the occurrence of defects. The aim of this paper is to provide basic information on the pattern and character of defects of high-rise residential buildings based on historical data. In order to determine the occurring frequency characteristics of work types of high-rise residential building defects, a logistic regression analysis is conducted. The order of frequency ranking is wood floor finishing material, tiling, marble finishing, built-in furniture, kitchen furniture, wallpapering, ceiling finish, wood door/window work, and aluminum window work. For analysis, the dependent variable is set for the case where a work-type defect occurs between two high ranked ones. The independent variables are set for an elapsed year from the time of building completion (usage year), including structure type, the floor area of each household, and the location of where the defect occurred. The results show that structure type affects the occurrence of built-in furniture defects and the locations of the area of the defect affects whole work-types, but floor level defects do not occur in all cases. Furthermore, the wood door/window work does not decrease with time, though other work-types decrease. This result showed that the wood door/window work needs to be managed by life-cycle management. |
