Before introducing the classification of steel structure building, please briefly introduce the basic concepts of ferrous metals, steel and non-ferrous metals.
Roofing works for sub-project acceptance, the quality should meet the following requirements:
The base positioning axis and the support steel cylinder surface elevation exceed the allowable deviation of the specification.
Reduce the load, change the calculation of graphics, increase the original structure of the cross-section and the connection strength, to prevent crack propagation
When the welding is strengthened, the high temperature will cause the organization and performance of the welded parts to deteriorate.
The following principles shall be observed in the design calculation of the reinforcement structure.
Steel structures buildings are faster in construction, versatile, simpler in structural behavior. Con is just economy and the insane precision required.
Steel structure system can be accurately designed and analyzed, making the structural reliability of the steel structure housing is better than that of brick masonry building.
1. Curved box steel girder is the important force of the roof structure, the position of the joint of the bar itself is more, and it is easy to produce angular deformation, distortion
