Retrofit of Artificially Perforated Shear Wall in Existing Dominant Wall Structure
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 induced by remodeling. One of these specimens was tested in the as-built condition and the other two were retrofitted prior to testing. The retrofit involved the use of carbon fiber sheets and steel plates (a thickness of 3mm) over the entire face of the wall. The test results showed that the failed specimens had shear fractures and that two different types of retrofitting strategies had different effects on the strengths of each specimen.
