| Abstrakt: |
Seven 2/3-scale interior slab-column connections were tested to quantify the effects of earthquake damage, and the efficiency of various rehabilitation techniques on repairing seismic damaged slab- column connections and improving the two-way shear strength of deficient connections. Three alternatives for rehabilitating slab-column connections were experimentally evaluated: (i) installation of steel collars, (ii) installation of external Carbon Fiber Reinforced Polymers (CFRP) stirrups, and (iii) application of well-anchored CFRP sheets. All three techniques increased the connection strength and improved the residual capacity after punching failure. |
