How to consider the influence of base displacement on steel structure
The vertical deviation is too large and the height of the column column below the design elevation. The high-rise steel structure engineering, steel structure engineering of column soleplate gap is too large or difficult iron pad placed in the assembly process will. It is also found that the spacing between columns is too large or too small, and it is often found that the top elevation at both ends of the beam is inconsistent.
A variety of raw materials will exist in a variety of deformation, steel structure in prefabricated projects will appear in a variety of geometric size deviation. Such as bending, uneven and non vertical and so on need to be corrected, correction works often use heating correction, the correction of the components will appear heating zone embrittlement of the scene. Material cutting or welding deformation often happen, such as a variety of complex twists and turns, distortion and warping deformation etc..
When performing the structural search and acceptance, the steel structure is completed after installation. Often issued axis displacement, the vertical deviation is too large and the height of the column column below the design elevation. In the high-rise steel structure engineering, it is also found that the spacing of each column is too large or too small, and it is often found that the top elevation at both ends of the beam is inconsistent when searching the top of each layer.
