Abstract:
An experimental investigation of a simple technique for retrofitting existing reinforced masonry walls with external steel plates to significantly enhance out-of-plane flexural strength is presented. Five full-scale 4-ft-wide x 9.5-ft-long spans were built and tested with static cyclic loading. Parameters known to affect the behavior of the specimens, including shear or compressive failure of the masonry, bearing failure of the masonry under the through-bolts, as well as the effect of cyclic loading on strength and stiffness, are considered. Test results show that this simple retrofitting technique is effective in enhancing the wall out-of-plane capacity greatly.
