High-rise Building Glass Curtain Wall Structural Analysis And Computer Simulation Applications

The problem which aims at overcoming the shortcomings in traditional design method and improving the efficiency of curtain wall design is presented in this paper.The development and actuality of curtain wall structure at home and abroad are firstly discussed. After the analysis of the common technique in curtain wall, a set of calculate method on wind pressure and wind libration force which acts on curtain wall is presented. Comparing with the currently predigesting calculate of wind pressure on curtain wall, the result in this paper is more precision and more practical. Based on these, two mechanics models which prefer to different curtain wall structure are presented. The force condition of glass curtain wall board under wind load is analyzed, that is based on the curving theory of small deflection elastic lamella and doubled > single triangle progression method. And then two different curtain wall structure examples are given to define the application of this method.Mechanics calculate model of continuums girder about pole in curtain wall is presented later in this paper. The problem is settled by using the three flexing equation of continuums girder. And then by calculating midpoint displacement, shearing force, flexing square of different spans continuums girder, a conclusion is drawn that the four points three spans continuums girder model is more available in calculating poles in curtain wall structure. Comparing with the double sustain girder model which is currently used in curtain wall design, the result in this paper is more precise.At last, according to the experience in curtain wall component checking, some suggestion about curtain wall joint are represented in this paper. And then a practical calculate example is given to explain these suggestion.Aiming at the complex calculation in this paper, all the calculation problems are resolved by computer programs which are based on MATLAB5.3 program. The program adopt peopleæ¢'omputer alternating mode which makes it reasonable union of accuracy and shortcut in curtain wall design.
