ALGORITHMIC DESIGN OF LOAD-BEARING STRUCTURES OF INDUSTRIAL BUILDINGS USING VISUAL PROGRAMMING

The process of designing load-bearing structures using information modelling is analysed. High labour intensity of variant elaboration, complexity of data transfer between information and structural models of load-bearing structures, non-perfection of existing tools for converting information models into structural models and vice versa are noted. The use of visual programming for creation of scripts automating information and analytical modelling in CAD is suggested. The possibilities of visual programming for forming scripts of automated modelling of load-bearing structures are considered. The algorithm in the visual programming environment for designing load-bearing structures of industrial buildings, which realises the automated formation of the design and information model of the frame according to the given parameters of the building and structural solution, is considered. The use of visual programming allowed parameterised formation of information and analytical models with automated application of snow and wind loads. Parallel formation of models according to the rules configured in the script increases the degree of design integration and can reduce the number of errors in the models. The comparison of labour costs in the design of load-bearing structures by parametrized and non-parametrized methods on the example of two construction objects has been carried out. The increase of design productivity at the stage of information and analytical modelling when using parametric script has been revealed. The considered approach can be used for variant design and optimisation of structural solutions. Interactive change of models at change of input parameters and continuous feedback on target indicators facilitate the search of optimal design solutions. Parallel generation of design and information models by means of scripts allows to reduce the labour intensity of model development in comparison with the sequential method.
