Rebar arrangement logic optimization method for complex construction nodes

Abstract

The application belongs to the technical field of electric digital data processing, and relates to a complex construction node steel bar arrangement logic optimization method. Steel bar geometric parameters and anchoring constraint relationships are extracted, a directed acyclic graph is constructed with steel bar sections as nodes, spatial occupation intersections as edges, and construction sequences and construction specifications as weights; spatial arrangement conflicts are converted into loop identification problems in the graph, and graph coloring processing is used to divide conflict edges into levels and give avoidance priorities; based on topological sorting traversal, bending avoidance directions and offset rules are determined according to coloring values; offset compensation calculation is performed through topological reverse sequence, offset values are reversely transmitted to non-conflict steel bar sections along the edges, and arrangement coordinates and bending node logic sequences are output. The application converts serial collisions into graph structure operations, overcomes chain collisions and local deadlocks caused by serial avoidance, and eliminates space occupation caused by avoidance.
