In this paper, cyclic load tests were performed, in order to investigate the restoring force characteristics of prestressed concrete beams in beam-column assemblies. The variables adopted in the tests were the size of the column, the amount of ordinary reinforcement in the beams, prestress and the location of the column in frame i. e. exterior or interior. Through these tests, it was found that the restoring force characteristics of prestressed concrete beams depended on the effect of the diameter of ordinary reinforcement in the beams and the locations of the columns in. frames. On the basis of the test results, a restoring force characteristics model was proposed in order to predict the hysteretic behavior of prestressed concrete beams in frames. The equivalent viscous damping ratio obtained from the model agreed with the test results.
