Study Of Temperature Effect Of The Super-Length Frame Structure

with the increase of the number of large-span, large-area and large-space buildings in citys,the overlong Frame structure be used popularly. Some overlong Frame structure is not supposed to be located or at least frequently located in average budings for the requirements of their functions.So overlong Frame structure whose lenths are more than 100 metres are ever-increasing by popular.The tempreture defomation and tempreture stress made by the tempreture in the overlong Frame structure,if not properly tackled,may cause cracks and damages in structures,may even affect the operations of the structure.Because the complex of the overlong Frame structure,there exist considerable diffcultys in calculating the tempreture stress of overlong Frame structure .This made the research fellows and designers simplified calculating methods. But the deducted conclusions are inevitably inacculate .In China,temperature variations are even not take into c onsideration in overlong Frame structure designing at all, just only some construction treatments considered. Therefore, temperature problem is one of vitally important research topics in structure designing of overlong Frame structure.Researches of this paper are just carried out under such a background at present .The main woke done in this paper will woke in overlong Frame structure in the future.which mostly include several studies below:1. model research.of overlong Frame structure buildings with Finite Element Model. Finite element analysis method is applied in temperature stress c alculating'problems of overlong Frame structure to make the integral te mperature stress analysis in order to overcome the shortages of considerable errors resulted from the simplified hand-made calculating method, and the lacks of structural integrality coming from the local calculations of each component and the other problems similarly involved.A- lso the modeling of the overlong Frame structure is provided .The whole structure of overlong Frame structure is chosen as an object of study, and a worldwide used large-scale structural analys is program named Super SAP93 is also chosen to decentralize the structure into elements. The beams and columns of the structure are modeled as dimensional beam components,an d the floor slabs, are modeled as.dimensional slab components.Then the p ractical integral structuralan alyzing models of the overlong Frame...
