Abstract
The invention relates to a database-based method for converting a three-dimensional building model into a structure calculation model in three-dimensional building model information in the field of building design. The method includes the steps: preprocessing the three-dimensional building model; extracting structure information of components in the three-dimensional building model; keeping structure information in the building model in a database; building a structural analysis model by the aid of the information in the database according to the finite element theory; generating a finite element model and a conversion process log file; checking and revising the generated structure model by comparing the conversion log file; and defining calculation adjustment parameters required by building design specifications. The method overcomes the shortcomings of building an existing structure model, the structure calculation model is efficiently and quickly built, and height consistency of the structure model and the three-dimensional building model is realized.
Description
Technical field
The present invention relates to standardization collection and the treatment technology and the database technology of three-dimensional building model information in the architectural design field, can be used for setting up the Structure Calculation model fast based on all kinds of BUILDINGS MODELSs.
Background technology
The architectural design industry that quick and precisely is based upon of Structure Calculation model has special significant meaning, is promoting technological progress, scientific and technical innovation, is raising the efficiency, and guarantees that designing quality and secure context play an important role.And since the Structure Calculation model itself be with the BUILDINGS MODELS Different software in set up; With the consistance of BUILDINGS MODELS; Rebulid on the accuracy of structural model, the model of structure and architectural discipline is linked up wastes time and energy, and has been difficult to adapt to new design-calculated requirement.
Summary of the invention
Technical matters to be solved by this invention is to utilize database technology and finite element theory, based on the three-dimensional building model, sets up the Structure Calculation model rapidly and accurately, satisfies structure department to the demand on Structure Calculation model accuracy and the efficient.Information processing and the database technology that the present invention relates to have very important significance, and with the drawback that the foundation that solves the existing structure model exists, the efficient of implementation structure computation model set up the height consistance of structural model and three-dimensional building model fast.Can also make full use of the building element information in the database, be other professional significant data source such as cost, construction, energy consumption analysis.
According to the requirement of database technology, in conjunction with the characteristics of three-dimensional building model, take all factors into consideration the identical point and the difference of various buildings and structured data, model information treatment scheme of the present invention is following:
1. the pre-service of three-dimensional building model: definition member parameter, like material, size, cross section, load etc.;
2. extract the structural information of member in the three-dimensional building model, the common fingerboard of said member, plate, post etc.;
3. structural information described in the BUILDINGS MODELS is retained in the database;
4. utilize the information in the database to set up Structural Analysis Model according to finite element theory;
5. generate finite element model and transfer process log file;
6. contrast conversion log file is checked correction to the structural model that generates;
7. the calculating adjustment parameter of definition code of building design requirement is utilized finite element software analysis.
Combination degree according to different finite element structural analysis softwares and building code; Delimiting period reduction coefficient, shearing adjustment coefficient, earthquake adjustment coefficient; Adjustment parameters such as moment of flexure amplification coefficient, beam rigidity amplification coefficient, beam moment of torsion reduction coefficient, company's beam rigidity reduction coefficient are carried out computational analysis in beam-ends moment of flexure adjustment coefficient, the girder span.
Beneficial effect of the present invention is:
(1) the invention solves multi-disciplinary of structure and building and link up the problem that model is wasted time and energy
(2) the present invention is based on the building three-dimensional model and set up the Structure Calculation model fast and accurately, improve structural design personnel's the efficient and the precision of Structure Calculation model, greatly facilitate designer's use.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified:
Fig. 1 has described process flow diagram of the present invention.
Embodiment
Step 1-7 shown in Fig. 1 has shown the step that The model of the present invention is set up.
Member in Fig. 1 step 1 and the step 2 is based on object properties, can define information such as material, cross section, size, load.
Structural Analysis Model comprises information such as node, unit, load, cross section, constraint based on finite element theory in Fig. 1 step 4.
Building element information in Fig. 1 step 3 in the database has versatility.
Database is in consistency operation, has interface directly to be transformed into structure analysis software in the three-dimensional building prototype software.
The present invention is according to the analysis to three-dimensional building model and database operation technique and requirement, formulates and implements step based on the method for the building three-dimensional model transformational structure computation model of database, described in above-mentioned summary of the invention, and no longer tired stating.
