Glass curtain wall cable structure is a new type of curtain wall structure widely used at home and abroad in recent years. This kind of glass curtain wall brings people a light and transparent vision, especially suitable for large airport terminal, exhibition center, stadium, urban complex, super high-rise and other public buildings. It is well known that the cable structure bears the main function of the wind-resistant supporting structure of the glass curtain wall. It is a kind of special structure, because of its poor stiffness outside the plane, it will produce large deflection deformation under wind load, showing obvious geometric nonlinear characteristics. This new curtain wall structure system is favored by people inside and outside the industry because of its unique advantages such as simple appearance, simple structure, convenient construction, low cost, and no indoor space.
Because the glass curtain wall cable structure is only the peripheral protection structure of the main building, it can be established only if the main structure has the boundary condition as the supporting relationship of the cable structure. Under the external load, the cable tension is very large, which brings great adverse effect to the main structure. The relationship between the subsystem of the envelope structure and the general structure system of the main building is complex, and it must depend on the structural designer to use the knowledge of the structural concept design to make a reasonable judgment of the structural design. The so-called conceptual design generally refers to the basic design principles and design ideas obtained from the mechanical relationship between the main structure system and the types of curtain wall systems, the structural failure mechanism, and the engineering experience without detailed calculation, especially in some problems that are difficult to make precise and rational analysis or difficult to stipulate in the code. From the whole point of view to determine the curtain wall structure of the overall layout and detail structural measures of the macro control.
Adding material civilization also adds a lot of content of spiritual civilization. However, the application advantage of only pipe and cable structure is obvious, because the glass curtain wall cable structure must rely on its boundary structure, if the modern curtain wall design will produce many negative effects, and even lead to design safety accidents. The design management is not in place leading to a variety of hidden dangers in engineering practice. Conflicts between various units also affect the construction period, seriously affect the quality of the project, resulting in unnecessary economic losses and even safety risks. Especially for the long span cable structure design must be careful.
