[0081] The application of this invention can improve modeling efficiency. Through automated rule matching, designers only need to input basic parameters to quickly generate steel node models that meet the requirements, reducing manual intervention and repetitive work, improving the consistency of multi-node type modeling, and avoiding design differences and errors caused by manual operation.

[0082] The application of this invention can standardize the design process, and all generated models strictly conform to preset rules, ensuring that the design meets industry standards and project requirements. With the rule base supporting dynamic expansion, it can quickly respond to changes in different specification requirements, which is particularly advantageous in international engineering projects.

[0083] This invention is more adaptable to the needs of complex engineering projects. The steel structure node types are complex and diverse, and it can ensure that the system can adapt to the special node requirements in line engineering, such as nodes with special stress or nodes with different construction methods. For heterogeneous nodes, designers only need to add or modify templates to support new node types.
