Analysis And Optimization Of Design And Optimization Of A Super-High-Rise Structure

With the continuous development of China's economy,in recent years in China,the rise of a high-rise building boom.In this case,a large part of the high-rise buildings of the height and complexity are beyond the limits of our current norms,the formation of a variety of height overrun,flat or vertical irregular high-level structure.It is necessary to select the appropriate structural system and design calculation under the various effects of the overrun high-rise structure in at least one direction and multiple directions with the seismic conceptual design.This paper summarizes the development of high-level structures at home and abroad,and expounds the criteria and some control measures and requirements for overweight high-level in the specification.On the basis of extensive reading of the literature,the structural analysis and optimization of a certain high-level engineering example are carried out.The structure is calculated by using SATWE and PMSAP in PKPM.The conventional multievent seismic elasticity analysis,elastoplastic time history analysis,Under the earthquake under the elasticity analysis,the mid-earthquake non-yield calculation and the shock under Push-over push analysis.In addition,in the temperature effect analysis process,the temperature difference calculation and the temperature difference effect of structural displacement and shear change analysis.In the whole process of structural simulation,the creep shrinkage analysis of concrete after 10 and 20 years was carried out.The main conclusions of this paper are as follows: the shear load ratio,axial compression ratio and interlaminar displacement angle of a certain high-level structure under the action of earthquake meet the requirements of the specification.Under the action of temperature,the structural displacement and deformation meet the specification requirements,It is concluded that the shrinkage and creep of structural concrete after 10 years and 20 years will not have obvious influence on the use and safety of the structure,and the safety of its structure is demonstrated.
