The Application of Buckling Reinforced Bracing and Shear Wall in Retrofitting of Existing Concrete Building

Vulnerable buildings and their rehabilitation are important problems for earthquake regions. In recent decades the goal of building rehabilitation and strengthening has gained different rehabilitation systems. However, most of these strengthening techniques disturb the occupants, who must vacate the...
