In earthquake areas using structural systems with low weight but resistant materials, the effect of earthquake force is reduced. Also construction and utilization of existing steel and concrete structures are important factors in the production of greenhouse gases and other solid and gaseous wastes. In the last two decades, researchers have introduced CLT(Cross Laminated Timber), a kind of engineered wood Product, as one of the most suitable construction materials for development green building for the future cities. In the design steel-wood hybrid structure presented in this study, steel is used for the frame of the building, and horizontal and vertical CLT panels are used for the floors and shear walls. The lateral load resisting system of hybrid structure in this study is dual system of steel intermediate moment frame and CLT shear wall. In this study, to investigate the structural performance of the above mentioned system, a building of 6 stories with two types of structural systems including: A- Intermediate steel moment frame with concrete composite floor and B- Dual steel intermediate moment frame and CLT shear wall with the floor consists of the CLT horizontal panel, were designed using ETABS software. In the following, a structural frame of each structure with the two types mentioned systems was modeled in ABAQUS software and the behavior of 6 story frame with the two types lateral load resisting system was compared using pushover analysis. By comparing the weight of Structure with the two types of lateral load resisting system, it was concluded that the total weight of the building has decreased %22.01 in the structure with Dual system of steel intermediate moment frame and CLT shear wall, compared to the structure with intermediate steel moment frame system. In this study was concluded that using CLT panels instead of steel and concrete common materials, can to buildings with less greenhouse, environmental and noise pollution for produce materials and build structure, lower energy consumption, less weight, good seismic behavior, fast construction speed, renewable resource capability and flexible design be achieved.
