Seismic Design And Analysis Of A Large Commercial Center

With the development of urbanization in 21 Century,diversify buildings increase gradually.The demand of urban population has been more and more extensive and the requirement for building function has been improved by degrees this year.Nowadays,plenty of buildings with complex shape and novel structural system has been growing in many first-tier cities.The needs of shopping will be increased greatly with the external population pouring into the city,while the city center will emerge in large number of commercial buildings to adapt to public consumption.Therefore,the seismic design will be increasingly valuable in this general trend,for some special transfinite structure.This article will focus on the most common problems of irregular plane in a variety of transfinite structure to expound the basic theory of seismic design of building structure,research the calculation as well as analysis problems in engineer field,and do seismic analysis of the project example by using engineering calculation and analysis software.Moreover,the article also will elaborate the optimizing structure from different views and doing comparative analysis by selected several models.Studying the optimized structure of dynamic characteristics and displacement under the action of earthquake and the changes of the atrium opening floor internal force,is to provide some references for the designers in the future and propose the train of thought as well as research in the process of earthquake resistant design.In addition,aiming at the seismic design of this kind of engineering structure,the design objectives and measures are put forward,which can provide some reference for such similar transfinite projects.
