Abstract
In an appendix of Structural Calculation of Reinforced Concrete Structures, failure governed by slipping of wall panel is to be adopted as desirable failure pattern of earthquake resistant wall. There are many studies about slip failure of isolated earthquake resistant walls, but few ones about slip failure of earthquake resistant walls filled in frame. From the above point, experiments on three story and three span frame with a wall governed by shear failure are made under horizontal force. The analysis replacing the cracked wall panel with compression and tension bracings and applying the strength of slip failure for compression bracings studied by author is proposed. Computed results by the theory coincide fairly well with tested results through load-angle of slope deflection, load-end moment of surrounding frame and adjacent frame of wall panel, failure pattern, etc. Conclusions on experiments and theory of earthquake resistant walls governed by shear failure filled in frame are as follows. (1) To get ductile behaviors of frame with shear wall, sufficient reinforcement for shear and tensile force of surrounding frame are necessary. (2) The analystic method presented by author is appliciable for evaluating inelastic behaviors of frame with earthquake resistant walls governed by shear failure. (3) It is necessary to study not isolated shear wall but shear wall filled in frame for more accurate study of slip failure.
