According to current engineering practice, Confined Masonry (CM) buildings are weak in earthquake resistance and difficult in post-quake restoration.A new form of structure, i.e.Hybrid Masonry-Reinforced Concrete Structure (HMRCS), is investigated.By slightly increasing the sizes and reinforcement ratios of the RC members, i.e.beams and columns, which normally only act as confinement in a CM structure, now play an essential role in resisting the gravity load in HMRCS, while the masonry wall mainly resists the lateral earthquake load.To investigate the seismic-resistant behavior, pseudo-static tests on two full-scale HMRCS specimens were conducted,and the measured hysteretic curves were analyzed.Finite Element (FE) simulation was performed to verify the working mechanism and seismic response of the HMRCS specimens.The lateral displacement ductility factor obtained from the experimental results can fully satisfy the seismic requirement of structures.Therefore, HMRCS is reliable if its RC frame members and masonry walls are designed properly.Furthermore, the feasibility of using FE software to study the proposed HMRCS has been validated by comparing the experimental and simulation results.
