Abstract

The compact diameter steel cell dam with support frame is proposed as a new type of sabo dam which has wider opening rate and higher hydraulic function than the steel cell dam. In order to evaluate the total design including impact resistance design of this new type dam, the examination of the performance‐based design system is needed. In this study, the required performance analysis of environment, construction, maintenance management, structural safety, and debris flow capture was performed, and the necessity and the contents of new technical examination were extracted. Furthermore, some design examples were introduced, and it was shown that the choice of structure form increased according to the diversity of design conditions.

Key words:required performance analysis, cell dam, support frame, structural safety, debris flow capture
