The Design Method For The Anti-overturn Design Of The High-rise Isolation Structure

Isolation technology as a kind of passive control technique is simple,safe and economic,has been widely used in all kinds of low-rise buildings.With the development of social economy and construction techniques of innovation,isolation technology is gradually applied to the top of tall building even,therefore,in this paper,according to the fall of high-rise structure problem,do research in the following:(1)Selecting a typical high-rise structure,USES the surplus jianke software to analyze the structure modeling,and sums up the YJK software on top of base isolation structure design method and process,some concrete design key points and difficulties.(2)In view of the present rules and relevant regulations given in the structure of delay-independent conditions,respectively,for the overall overturning determination co nditions and isolation bearing in tension,through the numerical analysis,has been clea r about the two decide what is a necessary condition.(3)Analyzed the structure arrangement of the influence of the structure rigidity,r espectively analyzes the aspect ratio,shear wall quantity and arrangement,column spa cing,height and isolation bearing arrangement against overturning and the effect of hi gh-rise isolated structure under different intensity is given the value of height to width ratio,which summarizes the high rigidity structure design of the upper structure and layout of the isolation layer of specific methods and general law.(4)The isolation bearings are analyzed the influence of the parameter selection against overturning.Respectively discusses the isolation bearing vertical mechanical model of vibration isolation bearing value of the tensile stiffness and the influence of the isolation bearing internal structure against overturning,summarizes the resistive overturning the parameters of the design after bearing the design requirements and the specific method.(5)Analysis of the influence of ground motion against overturning.Respectively discusses the direction of earthquake ground motion input,single and double to ground motion,the influence of three to the ground motion input compared with the results of the vertical earthquake to simplify the analysis,summarizes the resistive overturning the design ground motion input design requirements and specific methods.
