prestressed steel structure of type

Guangzhou Steel tells you: prestressed steel structure of type

Evolved from a simple way to early prestressed girder crane, the beam stays up to now string truss, SUSPENDOME, cable dome, cable-membrane structure, modern glass curtain wall construction, pre-stressed steel structure wide range of innovative manner, broadly grouped as four categories.

First, the traditional stereotype.

In traditional steel construction systems, cable pretensioning arrangement is applied to improve the state of stress, reduce weight and cost. For example, prestressed truss, grid, mesh shell. Like ninghe Stadium, Panzhihua City Stadium and the Beijing Olympic Badminton Hall prestressed grid, lattice shell. Now, the domestic and international terminals, convention centers are widely used string truss also fall into this category. Another is the application of engineering long suspension structure, for example, Beijing Workers Stadium, Zhejiang People's Stadium and the like. Its structure and stability of the load-bearing cable cable cable lines composed of two groups, the purpose of prestressing is not reduced and adjustment of internal forces, but given the guarantee structure stiffness.

Second, hanging stereotype.

Constructed from vertical support system (pillar, door frame, arch, etc.), with a sling and roof three parts. Support system above the roof, its drooping cables hanging roof top. For hanging 索施加 prestressed roof to adjust the internal forces, reducing deflection and the formation of elastic supporting structure of the roof. Because the support system and slings exposed to the atmosphere, pointing blue sky so called exposure configuration. For example, Jiangxi Stadium, Beijing Chaoyang Gymnasium, Hangzhou Huanglong Stadium, and Changchun City Stadium and the like. Guangzhou Steel

Third, all the tension type.

Innovative construction systems belong, span configuration abandon the traditional flexural members, all from the cable system by Zhang and membrane surface and the compression strut, whose roof structure is extremely light design novel, is a leader in advanced structural system, For example, the main event in Seoul and Atlanta Olympic Hall, Munich Olympic stadium complex, and Inner Mongolia Erdos Iraqi flag Cable Dome Sports Center.

Fourth, tension metal film type.

Metal diaphragm is fixed to the top marginal member, either as envelope structure, and as a load-bearing structure participation of all carry the load. Or in tension state, the diaphragm is fixed to the top of the skeleton structure, a space block structure, covering the span, prestressed new system both in theoretical guidance structure forming born. This type has been used in several of the 1980 Moscow Olympics main event venues, such a structure is not yet completed system. Guangzhou Steel
