摘要：

Hybrid masonry structures (HMS) combine the ductility of steel components with the shear strength of reinforced masonry panels. There are three types of hybrid masonry systems, differentiated by the load transfer mechanism between the steel frame and the masonry panel. Type I structures have been thoughly investigated both experimentally and numerically, and have been successfully deployed in low seismic areas. However, there are no mature standards that govern the full scale designs of the other two types of structures. There is also very little research performed to analyze the non-linear load transfer mechanism, and quantify the contributions of the major components to the system's structural performance, which limits the use of HMS in construction. This paper focuses on investigating the influence of the non-linear load transfer mechanism on the performances of the three types of typical HMS, such as lateral strength, stiffness, energy dissipation capacity and deformation pattern. The usage of connectors in type II and type III hybrid structures is also discussed. Recommendations for the use of HMS in seismic areas are provided based on the numerical studies. © 2023 Elsevier Ltd
