BIM and calculation software bi-directionally connected structure design method

Abstract

The invention relates to the technical field of structure design, and discloses a BIM and calculation software bi-directionally connected structure design method. The method comprises the following steps of: 1, establishing a BIM three-dimensional model and a view in a BIM platform; 2, appointing a BIM analysis model in the BIM platform, and inputting a structure in the model to calculate all the required information; 3, analyzing the BIM analysis model in the BIM platform so as to form a data file; 4, loading the data file formed in the last step in calculation software and carrying out structure calculation; 5, checking and analyzing the calculation result in the calculation software, if a standard requirement and an engineering design requirement are satisfied, going to step 6, and otherwise, returning to the step 1 to carry out modification; and 6, reading the calculation result in the BIM platform so as to generate a drawing and a table. According to the method, the structure design efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of structural design, in particular to a structural design method for bidirectional communication between BIM and computing software. Background technique [0002] As a new three-dimensional design technology, BIM ((Building Information Modeling) has gradually been widely used in the design, construction, operation and maintenance stages of engineering construction in the past ten years. However, in the engineering design stage, structural professional The use of BIM design is still very lagging behind. Usually, BIM models are passively created for professional use in construction, electromechanical, etc., and almost no active use of BIM technology for structural design. The reason is that the efficiency of using BIM technology for structural design is much lower than that of traditional two-dimensional design method. [0003] To this end, about 10 years of research have been carried out at home and abroad,...

Problems solved by technology

The essence of the first method is to calculate the software as the center, first perform structural calculations and then create BIM models and drawings. This method does not conform to the usual design process and cannot be widely used in structural design; read in the modified calculations from the BIM platform When making a model, it is necessary to compare the models to confirm whether the modification is based on the calculation model or remain unchanged. The operation is quite cumbersome; Parts, buttresses, markings, dimensioning, etc. need to be supplemented and modified accordingly. The workload is heavy and error-prone

In the second way, whenever the BIM model is changed, it needs to be checked and modified in the calculation software after it is rewritten into the calculation software, as well as to verify, modify and supplement the loads and related settings around the modification. cumbersome

In the third way, engineers need to keep in mind where the latest model is at all times to avoid the wrong direction, and after the BIM model is transferred to the calculation software, it is unavoidable to find and verify the surrounding loads and related settings of the modified place. Import it into BIM Calculation model can not solve the problem of model comparison and loss of associated primitives

[0004] It can be seen that the current connection method only simply realizes the conversion of part of the data between the BIM model and the calculation model, and does not make full use of the technical characteristics of the BIM platform, resulting in low structural BIM design efficiency, which can only meet the design requirements of construction drawings for simple structures , cannot be widely promoted in the BIM design of structures, resulting in the current situation that structural professionals are unwilling to actively adopt BIM technology for design
