Applied Research On Glass Curtain Wall And Steel Structure In 2014 Qingdao International Horticultural Exposition

Its main body adopts space steel structure system and glass curtain wall frame system on the surface in 2014 Qingdao International Horticultural Exposition.The steel structure is used widely in architectural structure because it install easily, has short construction period, has light weight, decreases the earthquake effect, has a good seismic performance and is less about pollution of the environment.It analyzes the reasons for these problems, take measures for reinforcemen and analyzes the validity of these measures by the finite element according to method and process of the design and construction and appeared problem frequently. It puts forward the most reasonable structure and the structure of the whole form for reference for engineering application according to the study of various factors and the structure form by ANSYS. By ANSYS theoretical analysis of glass curtain wall steel structure nodes and considering the influence factors of its mechanical properties, it designs more reasonable form of node and hope be helpful to the design and construction personnel. It is concluded that the most reasonable form of node in order to the engineering application and reference and has a better economic effect and social effect according to the study of mechanical properties, derivation of theoretical formula and the structural finite element analysis of steel structure and glass curtain wall.In order to understand more of the mechanical characteristics of steel structure node, we build a steel structure node and simulate it in the action of shear force alone, bending moment alone, and the combined action of them, systematically analyzed the mechanical characteristics of the top flange and the top ring plate, the bottom flange and bottom ring plate, the web of the steel beam and steel tube column. Through the analysis:(1) the maximum stress point of the steel structure nodes first appeared in the areas where the steel tube column touching the ring plate and the bizarre point of the beam flange touching the ring plate, and first yield in these area. When the steel structure nodes under the action of bending moment and yield, the stress of the steel tube column and beam web is very small, the bearing capacity of the main steel structure node is determined by the beam flange, so when the effect of the moment is bigger than that of shear, we should strengthen the strength of the beam flange.(2) The displacement of steel structure nodes in the action of bending moment is very small, but larger in the action of the shear. The steel tube column, after pouring concrete, improve the bearing capacity of the steel structure node to a certain extent. The stress of the steel tube column is very small when the steel structure nodes in the combined action of the bending moment and shear force.
