SEISMIC PERFORMANCE OF AN EXISTING RC FRAME RETROFITTED BY PRECAST PRESTRESSED CONCRETE SHEAR WALLS

摘要

This paper describes the seismic performance of a new retrofit method. This new retrofit method is using precast prestressed concrete shear walls on outer frames of a 5 storeys existing reinforced concrete building. In order to develop this new retrofit method, two types of specimens were carried out. One type is a part of a pressure joint between the shear wall and the existing column or beam, and another is a frame part which is lower 2 storeys of this 5 storeys building.
