    Abstract

    The purpose of the link column frame is to provide acceptable collapse prevention performance and to allow for easy repairs following a moderate earthquake. The experimental and analytical studies that are presented in this article mainly focus on the behavior of normal and link column reinforced concrete (RC) frames with different connection configurations. Quasi-static cyclic load experimental results are presented and discussed for seven 1:3 scaled RC frames with and without link columns. There are various connections between the main beam and the link column. With respect to experimental results and using ANSYS software, the finite element model related to these frames is made and calibrated, and then nonlinear analysis under cyclic static loading is performed. The experimental results show that the yield strength and ultimate strength capacities of the link column frames increase with a decrease in relative story drifts, especially in the hinged link column frame that was designed according to IS 12303-1987, Criteria for Design of RCC Hinges. Greater amounts of energy were dissipated by the link column frame, which has a hinge connection designed according to IS 12303-1987; this connection was found to be more effective and reliable. When compared with the normal frame, the link column frame with the proper connection dissipates more energy by shear yielding of the link beam. The additional link provides extra stiffness to the entire system.
