This paper presents the results of the experimental study on the seismic performance of Reinforced Concrete Column-Steel Beam frame systems with centrifugally molded PCa Columns, which are made using the production line of PRC piles. At first, two basic tests, the tensile test of Non-Diaphragm-pipes and the compression test of the joint filling mortar between the PRC Column and steel pipe, were carried out. Afterward, two interior beam-column joints were tested under reversed cyclic loads while subjected to constant axial compression. Finally, a procedure to evaluate the seismic capacity of steel beam-PCa column joints is presented.
