Abstract |
A series of three shear wall specimens were tested under constant axial stress and reversed cyclic lateral loading to evaluate the capacity of seismic retrofit proposed for the shear wall with the opening induced by remodeling. One specimen was tested in the as-built condition and the others were retrofitted prior to testing. The retrofit involved the use of carbon fiber sheets and steel plates (thickness ; 3㎜) over the entire face of the wall. Specimens were 1/2-scale representations of a one-story wall in a Korean apartment building that was built in 1980. The test results showed that failure mechanism of specimens governed by shear fracture and the strength of specimens was varied with according to the retrofitting strategies.
