Experimental Research on out of Plane Eccentric Compressive Bearing Capacity of Reinforced Block Masonry Shear Walls/Yu Fang, Zhai Ximei(School of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China)
Abstract:16 reinforced concrete masonry walls have been tested under out of plane eccentric load. The form and mechanics of failure, the bearing capacity, the characteristics of deformation and mechanical behavior of vertical bars under varying eccentricities are learned. The test results are compared with the predicated values recommended by the Code for Design of Masonry Structures, and new opinions are put forward. Influence factors of reinforced block masonry shear walls bearing capacity out of plane are discussed, which can provide reference for the calculation of bearing capacity on reinforced block m
asonry shear wall structure.
Keywords:concrete block masonry; out of plane; reinforced; eccentric compressive; bearing capacity
