| The light steel—reinforced concrete shear wall is based on the reinforced concrete shear wall. This kind of structure, forming by pouring self-compaction concrete in light steel-lattice, is especially suitable for civil multi-layers and high buildings. Contrast to traditional masonry structure and reinforced concrete shear wall structure, this structure has some of advantages such as better energy saving, less cost, and more safety.However, the method of the design of the light steel—reinforced concrete shear wall is the same as the reinforced concrete shear wall at present. Because of being a new structural system,researches on the light steel—reinforced concrete shear wall are not adequate yet. This thesis include some new researches on this structure as follows:1. Determination of the anchorage length of light steel by performing experiments and theoretical analysis on stick strength between light steel and concrete.2. Establishment of the shear strength formula of reinforced concrete shear walls and analysis of mechanics behavior of horizontal distributed bars in the walls.3. Conclusions based on the research on seismic behavior of reinforced concrete shear walls such as ductility and destruction forms.4. Nonlinear finite element analysis is completed using ADINA soft—ware. Based on the calculation results of models with variable height—width ratio, axial compression ratio, steel reinforced ratio and reinforcement steel at the end of shear wal1, ductility and destruction forms are comprehensively analyzed. And design suggestions are given to light steel—reinforced concrete shear wal1, which is axial compression ratio affects obviously affect its ductility and the reinforcement steel at the end of shear wall has less effect on it. |
