SHEAR CAPACITY PREDICTION OF CONFINED MASONRY WALLS SUBJECTED TO CYCLIC LATERAL LOADING

摘要

This study describes an analytical proposal to predict lateral shear capacity of confined masonry wallsnthat fail by diagonal splitting, where the maximum shear is evaluated as the dowel action of confinedncolumns’ reinforcement added to the shear capacity of the plain masonry panel. In order to validate thenproposed approach, experimental test results and gathered data from literature were used. The experimentalntests concerned two confined clay brick walls subjected to different level of gravity load and cyclic lateralnloading. The applicability of some empirical formulae found in literature regarding the stiffness degradationnwas investigated. Good correlation between the predicted lateral resistance using the proposed approachnand all data was achieved
