Study On Seismic Performance Of Super High-Rise Building In High Intensity Region

Since the 21 st century,as China’s economy and the rapid development of technology continues,the pace of urbanization,more and more scarce land resources,high-rise buildings,more and more widespread than in the more developed cities.For general construction,according to "Seismic Design of Buildings" requirements,"three levels,two-stage" seismic concept.However,for the overrun construction,because it does not meet the specifications applicable conditions,in order to achieve its seismic performance requirements,but also for its specialized demonstration study.For our senior overrun accordance with the "High-rise buildings earthquake-proof construction regulations" and the "National High-rise buildings earthquake-proof engineering special examination techniques" requirements analysis and design.Because there is no uniform standard study High-rise building seismic performance and clear basis for the design,engineers need according to the specific circumstances of the actual project,according to the specifications and materials as well as their own experience related to a careful feasibility studies,design and research in order to gauge the top seismic.Since there is no clear current seismic design and research methods,especially at high intensity seismic zone on the seismic performance of buildings demanding circumstances,the present thesis research in High Intensity Area overrun by high-rise building seismic performance for Study on seismic performance of the same intensity zone of this type of high-rise buildings and representatives instructive significance.China’s implementation of the western development strategy and the strategy of central China,with the continuous development of the Midwest economy,high-rise buildings will generally be in the Midwest I appeared springing,but these relatively active seismic regions,the majority were high-intensity area,so high high-rise building intensity areas were studied seismic performance is very necessary.The thesis discusses the following aspects: the structure gauge type and extent of high-rise towers to discriminate,combined with the characteristics and overrun of the project,proposed seismic performance objectives;by ANSYS software to calculate the elasticity of small earthquakes analysis,and the use of Midas Building assisted analysis,by both the analyzed data verified by comparing the results of feasibility.According to "repair moderate earthquake" seismic fortification target,using ANSYS dynamicelastoplastic analysis of the structure,check the bearing capacity of the main components of the results,and stress were studied floor,determined to achieve the performance set.Accordance with the "earthquake not fall" principle,in rare earthquake,the buildings were using ANSYS nonlinear time history analysis of the structure of inter-story drift,inter-layer shear and top displacement analysis,validation of the project in under Strong earthquakes also meet seismic performance goals.In summary,the building meets seismic performance objectives.
