| Several times in the history of the global earthquake,earthquake damage ofhigh-rise reinforced concrete structure significantly.Seismic design of buildingshas been the focus of structural design.With the rapid growth in height, growingcomplexity which uses the elastic theory for structural analysis and design tomeet their needs, elastic-plastic analysis of seismic damage also proves need forElasto-plastic analysis methods is increasingly important.This article uses a different analysis software, a super high-rise building inseismic elastic stage calculations for analysis and comparison of calculationresults, verified the system of engineering structures and structure layout isreasonable.Validation in Super high-rise steel-concrete structure under seismicaction between different software for calculation of elastic displacement angleunder different conditions and cycles of correspondence.On this basis, usingelastic time-history analysis, calculations, structure display, displacement curvecomparison even, no mutation, displacement meet specification requirements.Then, on ABAQUS software constitutive relation for different materials andcalculation principles, for the project to be under strong earthquake dynamicElasto-plastic time-history analysis, based on the analysis results, pointed to keyparts of the structure to strengthen measures to ensure security under constructionin different seismic performance objectives, achieve the seismic designobjectives.The conclusion shows that, reasonable use of the general finite elementsoftware for dynamic elastoplastic analysis of buildings, in addition to providingconventional structural response under seismic loading, but also can providereal-time damage distribution structure and evolution of information, which canjudge the yield sequence of high layer structure under the earthquake and theweak parts accurately, provides information for optimizing structure seismicdesign, realize the goal. |
