ON THE FORCES OF SURROUNDING FRAME OF REINFORCED CONCRETE WALLS AFTER CRACKING

It is primary object of this investigation to get data to establish design formulas of surrounding frame of reinforced conbrete walls after cracking. Experiments on six reinforced mortal walls of which wall panel has three kind of reinforcing ratio, 0.35, 0.70 and 1.05 percent were made under pure shear. Considering the results of the experiments, the author proposed the analysis method replacing the cracked wall panels with compressive and tension bracings to get the force of surrounding frame of reinforced concrete walls after cracking. Computed results coincide fairly well with tested restults until the maximum load. The resisting mechanism of reinforced concrete walls and the effects of reinforcing of wall panels are well clarified.
