The tests of the model subjected to statically and repeatedly horizontal force were performed in orden to make basic data in a seismic design of reinforced concrcte cylindrical shell. Twelve models had parameters of compressive strergth of concrete for structural design and reinforcement ratio, namely, parameters of A series were F_c=250kg/cm^2, F_c=300kg/cm^2 and P_w=1/2P_t=0.6%, 0.9%, 1.2% and those of B series were F_c=250kg/cm^2 and P_w=P_t=1.8%. Test plan, load-deflection relationship, mode of failure, stress, rigidity and its reduction ratio were reported, and the summary of the test results were as follows : (1) The upper limit of the allowable plane shear stress in the elastic design was 0.13 F_c for A series model (P_w=1/2P_t=1.2%). (2) The empirical formula for the reduction ratio of rigidity was obtained, and Q-δ curve by its formula was compared with it by the tests and both agreed roughly.
