The Seismic Analysis In The Frame-Core Tube Structure With Flat Slabs

At present, the domestic and international high-level and super-high buildings, mainly use the frame-core tube structure and the tube in tube structure to resist horizontal seismic load and wind load. In the frame-core tube structure, the level component of contacting inside and outside is played an important role of coordinating deformation and transfering horizontal load.In general frame-core tube structure, The beams are the Level force transmission components. The flat slab structure, compared with beam slab structure have advantages apparent in the economyand effectivelyreduce the storeyheight, but relativelyweak anti-seismic capability. Based on the actual engineering——the frame-core tube structure with flat slabs "YINGLONG commercial building" devised byShenzhen institute of building research as the research object, the model is built byusing fem software MIDAS,and build ordinaryframe-core tube structure as reference system,do posh-over analysis of two models and studies the push bythe same earthquake effect both seismic performance indicators. Meanwhile establish ABAQUS model to do dynamic nonlinear analysis, focus on the damage of floor under the action of earthquake. Through the above two methods to evaluate seismic performance of the frame-core tube structure with flat slabs, Summarizes its common mechanical mechanism,failure modes and the applicable conditions. Finally, compare earthquake responses of each model with plates of different thickness.Through this research results, hope for the future of the high-rise building structural design provides a good example for reference, and puts forward a new thought and feasibilitystudy, to enrich structure seismic theoryresearch has certain theoretical significance.
