AIRTIGHT PERFORMANCE EVALUATION OF RC WALLS FOR BUILDING SEISMIC PERFORMANCE EVALUATION

Abstract

This paper focuses on the airtight performance of reinforced concrete (RC) walls used as exterior walls in a typical residential building (prototype building) in Japan. Air leakage tests were performed using two full scale RC wall specimens subjected to shear damage. The airtight performance of RC walls was evaluated using a fan pressurization method for air leakage. Furthermore, this paper evaluates a limit corresponding to function maintenance of the prototype building based on a design limit of the C value and the air leakage test results.
