Problems solved by technology

[0002] With the popularization and promotion of BIM technology, the application of BIM is becoming more and more extensive. However, at present, structural calculation and three-dimensional reinforcement modeling have not been well integrated into the scope of BIM design.
On the one hand, although some general-purpose finite element software can realize the import of BIM models, functions such as component design have not been integrated with Chinese standards
On the other hand, although the domestic structural calculation software also provides the interface of the BIM model, it has great limitations in the settings of loads and boundary conditions.

Embodiment Construction

[0026] The invention provides a method for calculating and three-dimensional modeling of structural reinforcement, comprising the following steps:

[0027] (1) BIM software performs concrete structure modeling to obtain the concrete structure model, and then imports the concrete structure model into the finite element software, and analyzes the internal force of the reinforced concrete structure in the general finite element software, and according to the internal force of each member of the reinforced concrete structure Carry out component design for each component in compliance with the structural code and obtain component design information; the concrete structure refers to the structure before reinforcement, and the reinforced concrete structure is the structure after reinforcement; the component design information includes strength design information, deformation Design information, crack design information, stability design information and reinforcement information;

Abstract

The invention provides a calculation and three-dimensional modeling method of structural reinforcing bars. The calculation and three-dimensional modeling method comprises the following steps of: (1) carrying out internal force analysis of a reinforcing-bar concrete structure in a general finite element software, carrying out member design conforming to structure specifications on all members according to the internal force values of all the members of the reinforcing-bar concrete structure to obtain member design information; (2) reading the member design information in the general finite element software and establishing association between the member design information and a BIM model; (3) reading the member design information in the BIM model, and generating a three-dimensional reinforcing-bar concrete structure model conforming to the structure requirements. The calculation and three-dimensional modeling method provided by the invention has the advantages that the internal force analysis can be carried out on the reinforcing-bar concrete structure, and the automation generation of the three-dimensional reinforcing-bar model can be realized.

Description

technical field [0001] The invention relates to a structural reinforcement calculation and three-dimensional modeling method. Background technique [0002] With the popularization and promotion of BIM technology, the application of BIM is becoming more and more extensive. However, at present, structural calculation and three-dimensional reinforcement modeling have not been well integrated into the scope of BIM design. On the one hand, although some general-purpose finite element software can realize the import of BIM models, functions such as component design have not been integrated with Chinese standards. On the other hand, although the domestic structural calculation software also provides the interface of the BIM model, it has great limitations in the settings of loads and boundary conditions. Contents of the invention [0003] Based on the above deficiencies, the technical problem to be solved by the present invention is to provide a reinforcement calculation and thr...
