Abstract The purpose of this work is to investigate the seismic performance of a four-story two-bay high-performance concrete (HPC) frame. Low reversed cyclic loading was conducted on a 1/5-scaled HPC frame. Seismic performance of the frame specimen was evaluated in terms of failure pattern, failure mechanism, deformation restoring capacity, displacement ductility and energy dissipation capacity. Test results showed that the specimen failed in the designed failure mechanism, and behaved in a ductile manner and larger energy dissipation capacity. The roof lateral displacement ductility coefficient was 5.69, and the 1st, 2nd, 3rd and 4th inter-story lateral displacement ductility coefficients were 7.95, 7.32, 5.06 and 4.69, respectively. An alternative design principle of frame structures is proposed in this paper to ensure that the beam sidesway mechanism occurs. Parametric analysis of ten frames with different developmental sequence of plastic hinges is conducted by a Finite Element Analysis (FEA) software framework OpenSees. The analytical results showed that the ductility supply of the frame designed according to the proposed design principle was maximized.
