AIRTIGHT PERFORMANCE EVALUATION OF RC WALLS FOR BUILDING SEISMIC PERFORMANCE EVALUATION

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. Theairtight performance of RC walls was evaluated using a fan pressurization method for air leakage. Furthermore, this paper evaluates alimit corresponding to function maintenance of the prototype building based on a design limit of the C value and the air leakage testresults.
