Anti-seimic And Isolate Anlysis Of High-riseBuilding

Along with our country city changes accelerated, tall building structures are in large numbers. Buildings beside the street one layer to three layers are generally designed for large frame structure, as shopping malls, hotels or office buildings. This paper studies the structure of high-rise building structures are relatively common type the business section of large space frame or frame-shear wall structure, and the upper shear wall structure, much as a residential. This paper summarizes the domestic and foreign relevant research results in the foundation, emphatically discusses the reinforced concrete frame-shear wall structure in high seismic intensity under the overall performance and analysis and isolation design, structure under rare earthquake seismic performance. At the same time on the basis of theoretical analysis, using PKPM software of reinforced concrete frame-shear wall structure of the system analysis.Mainly has the following several aspects of content:First, the overall structure of the seismic performance analysis, In SATWE elasticity analysis based on seismic wave, site category and the structure of fortification intensity are analyzed, in view of the actual engineering in elastic analysis on the structure in8degrees more than the site in earthquake is introduced, and the output-deformation curve, judge the whole structure of the seismic performance and ductility stand or fall.Second, to structure the whole isolation performance analysis. Use EPDA software calculation and analysis its basic performance and conclusion. In the EPDA elastic-plastic analysis based on seismic wave, site category and the structure of fortification intensity are analyzed, in view of the actual engineering in elastic-plastic analysis to the structure in8degrees site in earthquake Abraham is introduced, and has obtained the displacement curve, judge the whole structure of the isolation performance and ductility stand or fall.At the same time, some of the recent earthquakes show that only the structural design into "small earthquake not bad" and cannot effectively prevent the earthquake brought huge economic losses. But can the structural design more "strong", and keeps it in the fortification intensity even in Abraham earthquake can also "not bad", so as to avoid greater economic loss, also will become the researchers concern; Even if is only designed for "small earthquake not bad" structure, the fortification intensity and Abraham under severe earthquake seismic performance, or its ductility, and no specific quantitative index. So the structure in the fortification intensity and Abraham under severe earthquake seismic design and seismic performance, not only has theoretical and practical value for disaster prevention and mitigation and practical guiding significance.
