Abstract

Abstract: The installation and construction of large-span steel structures face the disadvantages such as high construction precision requirements,significant influence of temperature on steel components,and difficulty in controlling overall deformation.In traditional installation and construction of large-span steel structures,the total station is mainly used to measure and control the key nodes of the steel structure.This method has fewer measuring points,and the understanding of the overall deformation of the steel structure is not comprehensive enough.As a result,after installation,the steel structure often has a high degree of coincidence with the original design model at several main components,but there are large installation errors between the positions without measuring point control and the design model.Such large installation errors often affect the service life of the entire steel structure.In order to obtain the deviation between the construction quality of the steel structure and the design more accurately,this paper proposes a comparative analysis method based on 3D laser scanning and BIM to detect the construction quality of the steel structure model.Firstly,the 3D point cloud data of the overall steel structure after construction is obtained through 3D laser scanning,and the point cloud of the steel structure is denoised (separated from the background point cloud).Then,the BIM model is compared and analyzed with the point cloud of the separated steel structure,and the deviation values of the steel structure members can be quickly obtained.Taking the steel structure construction project of the Belarus national football stadium as an example,this paper quickly obtains the deviation between the steel structure and the designed BIM model through the proposed method,and calculates the deviation amount between the point cloud of the steel structure after construction and the designed BIM model.The results show that this method can effectively check whether the steel structure construction meets the design requirements,effectively guarantee the construction of the steel structure,and provide a new solution for the quality inspection of steel structure construction.
