The Seismic Performance Analysis Of High-rise Building Structure With Steel-reinforced Concrete Beam Conversion Layer

In recent years,there is a wide variety of prosperity of the high-rise structure,it went into a state of rapid development with each passing day.The high-rise building structure with conversion layer is a kind of relatively good in all forms of various structures among them.The conversion layer not only met the needs of using function,but also completed the transformation of different constructure form top to bottom.The conversion layer divided into the following types:box conversion layer,truss type,plate type,beam type and so on.The Beam conversion layer was widely used throughout the world took advantage of its excellent characters such as the transfer path of clarity and the stress of the simple form.The traditional reinforced concrete beam transformation layer which has some awful characters such as too much weight and construction difficulty could result in the beam conversion layer structure with new materials get fast development and won praise and favor.At present,the seismic performance of further and systematic researches for the high-rise building structure with new material beam conversion layer has very heavy and profound significance on the actual engineering application.In recent years,there is a wide variety of prosperity of the high-rise structure,it went into a state of rapid development with each passing day.The high-rise building structure with conversion layer is a kind of relatively good in all forms of various structures among them.The conversion layer not only met the needs of using function,but also completed the transformation of different constructure form top to bottom.This text conduct experiment researches of a steel-reinforced concrete beam conversion layer high-rise building structure,the research contents is as follows:1)Todoexperiment researches for the rules and regulations of the relevant beam conversion layer in the current design specification and theory study And conduct experiment researches for the seismic analysis method of the development of the high-risbuilding structure with conversion layer.2)According to the different conversion layer position on determing different values,modeling of different frame shear wall structure due to different conversion layer position by SAP2000,and then find response spectrum analysis and modal analysis of these different structure models,make analyse for its seismic performance from each vertex calculation scheme of vibration mode,structure of the displacement and interlayer displacement angle of the floors and the internal force distribution curve and so on many aspects,to explore the factors of this type structure in the elastic stage when the influence of the anti-seismic ability.3)According to different conversion layer and stiffness ratio on determing different values,modeling of different frame shear wall structure due to different conversion layer position by SAP2000,and then find response spectrum analysis and modal analysis of these different structure models,make analysis for its seismic performance from each vertex calculation scheme of vibration mode,structure of the displacement and interlayer displacement angle of the floors and the internal force distribution curve and so on many aspects,to explore the factors of this type structure in the elastic stage when the influence of the anti-seismic ability.4)To do elastic-plastic analysis on solution model of the value of different structures under frequent earthquake action and the function of the infrequent earthquake by Pushover,improve the reaction performance of structure under seismic action steps through performance points,load steps,maximum interlayer displacement angle and the distribution parameters and so on.Through the analysis of the elastic results contrast and comparison elastoplastic analysis results on different position conversion layer structure and the conversion layer stiffness than the structure of the up and down,finally obtaine the structure design of meet the requirements of the specification requirements and the most practical,there are far-reaching significance on the future design of similar structural engineering.
