Retrofit Using Increased Section Area Method of Artificially Perforated Shear Wall in Existing Wall Dominant Structure

摘要

The characteristics relating to high tensile ductility, High Performance Fiber Reinforced Cementitious Composites (HPFRCC) are being so that studied it'll be adopted in repair and retrofit of buildings. A series of three shear wall specimens were tested under constant axial stress and reversed cyclical lateral loading in order to evaluate the seismic retrofit that had been proposed for the shear wall with the opening. The retrofit involved the use of ECC and MDF, both of which are sprayed through the high pressure pump, over the entire face of the wall. The results indicate that two different types of retrofitting strategies cause the different effects on the strength and ductility of each specimen.
