Key points and engineering cases analysis for seismic design of frame-supported shear wall structures
Frame-supported shear wall structure can better adapt to the complex functional requirements of modern high-rise buildings,and has been applied in many high-rise buildings.With the urban renewal and urban TOD development,the frame-supported shear wall structure will be more widely used.The development process of frame-supported shear wall structure was briefly reviewed.The characteristics,advantages and disadvantages of three common transfer story structures,beam transition structure,box transition structure and thick plate transition structure,were introduced.The relevant provisions on the design of frame-supported shear wall structure in the current national norms,industry and local standards and group standards were compared,and the key points of seismic design of frame-supported shear wall structure were given.Finally,eight typical practical engineering cases with different periods,different transition methods and different building functions were analyzed.The results show that the limitation of high-level transition and thick plate transition for frame-supported shear wall structures can be appropriately relaxed in areas with 7 degrees and below,and the relevant standards and specifications need to be further revised and improved.
