Analysis And Seismic Design Of A High-rise Building Structure Seismic Response

First of all，Overrun with B level height high-rise city yingbin building project for theengineering background，the paper ensure that the Structural system solutions of resistance tolateral force which with tube-in-tube structrue was used in the preliminary design scheme bycombinated using the external framework and shear wall；According to the new issuedTechnical specification for concrete structures of tall building and the point of review Overrunhigh-rise building engineering，the paper designed earthquake resistant behavior of this superhigh-rise building structure.Main research work and achievements are as follows：Further defining the blue print of lateral resistant system which with tube-in-tubestructure. in view of the tube-in-tube structure suggest in the preliminary design scheme，thepaper conducted a preliminary modeling analysis using SATWE software，for preliminaryanalysis about the structure of the characteristics and the out-codes instance，we set upthree-dimensional finite element model of plate girder structure using ANSYS soft ware. Anddetermined the scheme of ultimate resistance structure to lateral force system.For the elasto-static analysis of tube-in-tube structure，we used the different softwareSATWE and PMSAP. compareing the leading indicator in different software，confirmed theaccuracy of structural modeling and computational analysis，at the same time，all the index ofthe structure was in accordance with the related national standards and norms. And foundsame weak link in the substructure.The elastic time history analysis under severe earthquake uised PMSAP software，andThe elastic-plastic time history analysis under severe earthquake used EPDA software.Comparing the result of elastic time history analysis under severe earthquake and CQC，theresult reveal that the Structural base shear come out by time-history method larger than CQCmethod， which means it must adjust the internal force and reinforcement components in thedesign. in addition，according the the result of The elastic-plastic time history analysis undersevere earthquake，it confirmed the Plastic interlayer displacement Angle of structureDeformation fit the specification requirements，Plastic deformation structure developmentcoincidence Structure the performance-based design goal.the paper’s design for the project of seismic performance，which made the super high-rise building adopt the Seismic calculation and construction technical measures，whichwere more Strict and effective then The current national seismic code. Yet it will need higherinvestment and longer design cycle. Therefore muti-arguments and Measured to determinewere need before adopting such structure scheme.
