Construction Application of Junction Nodes Between Multi-Way Beam and Ring Beam Based on BIM Technology
The junction between multi-way beams and columns involves complex stress distributions,with various structural beam skeletons interlacing and reinforcing bars piling up.Typically,large-diameter reinforced concrete ring beams are employed at these junctions to remove spatial constraints in assembling nodes of large-span multi-way beam structures.However,assembling nodes on ring beams is challenging due to structural collisions involving steel bars and plates.This paper utilizes Building Information Modeling(BIM)digital technology to establish models for junctions between ring beams and multi-way beams/columns.It formulates node assembly processes,calculates dimensions for components and steel reinforcement fabrication,simulates on-site assembly conditions,and determines the sequence for installing steel bars of various types.This approach addresses collision issues during node assembly in one go,ensuring construction quality and efficiency.Practical applications have demonstrated the advanced utility of this technology,suggesting its potential for broader adoption in similar engineering projects.
