Novel cross node based on bionic substructure topological optimization and optimization method

Abstract

The invention discloses a novel cross node based on bionic substructure topological optimization and an optimization method. A construction form based on topological optimization of a bionic substructure is adopted so that modeling and designing are carried out on a traditional cross node model, the dead weight of a cross node is reduced through the novel cross node obtained through an optimization method, materials are saved. Nodes utilize the materials more efficiently, the safety and stability of the nodes are improved, and the construction difficulty is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of steel structure nodes, in particular to a novel cross node and an optimization method based on bionic substructure topology optimization. Background technique [0002] The steel structure gradually emerged with the vigorous development of the modern iron and steel industry, which mainly refers to the structural system in which the structural components are made of steel. In recent years, steel components have been widely used in industrial and civil buildings, especially in frame structures and grid structures. From the perspective of mechanical properties and economics, steel components have a high strength-to-weight ratio. Under the condition of a certain amount of materials, they can provide higher strength and reduce structural weight, thereby saving materials, reducing transportation and installation costs, and reducing costs. the goal of. With its advantages of reasonable stress, economical materi...
