| Along with urbanization advancement speeding up, there are more and more high-rise buildings. Shear wall and tube structure are the primary kind of lateral force resistant systems in high-rise building. So shear wall with excellent behavior on resisting earthquake is urgency for project. New kind of connection methods which are adapted to use in composite shear wall with concrete filled steel tube columns are given in the paper, in order to study the work performance between concrete filled steel tube columns and shear wall, the experimental research and analysis for it has been done. Main contributions are listed as follow:1. Systemic experimental research on 6 different composite connections between concrete filled steel tube columns and shear wall under low cycle reversed loading have been done. The loading capacity, energy dissipation, hysteretic behavior, failure phenomena and working mechanism of each model has been analyzed. At the same time, experiment on 6 different types of anchorage plate and concrete beam specimen has been done. The anchorage mechanism of plate and concrete has been analyzed.2. Based on the experimental research, the loading capacity method for composite connections between concrete filled steel tube columns and shear wall has been given.3. Construction measures of composite connection between concrete filled steel tube columns and shear wall have been supplied, the working performance of composite connection in project is credible.Main considerations are concluded as follow:Based on the experimental research, The connectors with shape like letter U and reverse U which bond concrete filled steel tube columns and shear wall together, have excellent working behavior. For getting good anchorage behavior between steel plate and concrete, steel plate is adapted to made as bar with crankle. Construction measures of composite connection between concrete filled steel tube columns and shear wall can be used in aseismic design. |
