Stability analysis of high-rise steel structure joints based on BIM technology

Abstract

Because of its light weight, good orientation, strong seismic performance, high degree of industrialization, and short construction period, steel structure has relatively high investment efficiency and is widely used at home and abroad. At present, steel structures have been widely used in various complex high-rise buildings. Many high-floor buildings have many changes in building shapes and large spans, and their analysis difficulty and accuracy requirements are very high. Therefore, the stability analysis of steel structures is particularly important. Under the action of strong earthquakes, the welded parts at the nodes of the assembled high-rise steel structure are prone to rigid fractures, which are the weakest parts in the entire steel structure frame, causing damage to the steel structure nodes, and severe damage can lead to the collapse of the entire frame. In view of this defect, it is necessary to pay attention to the research on the stability of the prefabricated high-rise steel structure nodes. In this paper, combined with BIM technology, taking high-rise buildings as the research object, the linear buckling analysis of the structure is carried out, and the buckling mode, buckling weak parts and buckling load of the structure are obtained. Through the analysis of these data, this article evaluated the influence of the giant beam of this structure on the structural performance.
