Node modeling method and device and storage medium

The invention discloses a node modeling method and device and a storage medium, and the method comprises the steps: building a three-dimensional model which comprises a steel column, a steel beam and a node structure; a node parameter source file is obtained, and the node parameter source file is generated according to the node parameters; the three-dimensional model and the node parameter source file are bound, a node assembly is obtained, and the node assembly can be called by Tekla software to be used for recognizing a steel column and a steel beam in the to-be-processed model and used for modeling to generate a corresponding node structure. When the generated node assembly is applied to the Tekl a software, the to-be-processed model can be automatically identified, the corresponding node structure can be generated, and the modeling efficiency is high; due to the fact that the node assembly is obtained by binding the three-dimensional model and the node parameter source file, all node structures can be mod
