Analyse And Study On The Thick Plate Transition Layer In Tall Building Structures.

The mass of this paper is to discuss a new method of analyzing the thick plate transition layer in tall building structures.First, by summarizing the common design methods of thick plate transition layer concisely, this paper point out some shortcomings exist in them, like there are too many artificial assumptions, the non-pole mechanical properties of the plate isn't reflect accurately, the mutual affection between the thick plate and the columns or shear walls which connect to it is omitted, and etc. Second, to eliminate these shortcomings, the paper puts forward a new method .In this method, the first step is to analyze the whole structures of tall building which comprising the thick plate transition layer ,obtain the inner force of the columns and the shear walls which connect to the thick plate, these inner forces are the loads acting on the thick plate transition layer ;then create a combined FEA model using solid element that consist of the thick plate and the columns or shear walls which connect to it, and then work out the stress distribution of this model ; and then calculate the reinforce steel bra and steel bar by the way of Load equivalent law and stress law. The last step is to bring up the new thick plate design method. Calculate to the whole structure respectively in SATWE and PMSAP two kinds of software, compare with the result, for vast engineers and technicians' reference.Combining an actual instance, this paper analyzes the stress distribution of the whole thick plate transition layer. Deliberately, the point out the similarity and diversity between the common design methods and the method put forward by the paper ,these works interpret the feasibility and practicality of using the whole analysis method of placing steel bars in according with the stress diagrams in the design of the tall building..The works and some conclusions of this paper can be refereed to the design of the thick plate transition layer.
