Information technology aided designing of connections of precast frame structures

Purpose. Development information technology, computer-aided design connections unique prefabricated frame of reinforced concrete structures based on mathematical models of network structures and the theory of fuzzy sets, and designed for use in intelligent integrated decision support system, used CAD systems. Methods of designing based on the application of the algorithm for constructing the new compounds according to the technical solution. The algorithm based on the model of network structures and the principle of decomposition of the geometric model of the structure to the elements and then combining them into a new connection. The proposed model is adapted to simulate the condition of the structure of the automated system of support of decision-making in fuzzy terms and conditions of uncertainty. The algorithm based on the interaction with external systems design automation and includes an appeal to the intelligent system, which initially requires the use of natural intelligence with successive formalization and accumulation of information on the decisions taken in the knowledge base for the use of artificial intelligence systems. Results. The proposed technology develops and improves the possibility of using the existing computer-aided design and analysis and reduces the risk of making wrong decisions in fuzzy terms and conditions, the uncertainties associated with the human factor due to the double-checking that organized in a system of decision support. Scientific innovation. The proposed model of the process of design of compounds of precast frame structures, which designed for intelligent, integrated decision support system. For systems based on said geometric models constructed node knowledge base, that contains a database of geometrical models of the elements and nodes of the fuzzy rules of base composition. Terms of compositions based on fuzzy mathematical model of network structures, which has been adapted for the use of intelligent integrated systems design. The practical value. Realization of the proposed algorithm can significantly limit the number of suitable design options in a changing environment and, therefore, increase the degree of automation technology in the design process of compounds of precast frame structures. Carried out formalization of the model network structures allows simulation unique design features needed to create the technical documentation. Visualization of geometric models of elements nodes affects the reliability of the technology, as it allows to significantly reducing the risk of making inappropriate decisions at the stage of acquiring knowledge using natural intelligence.
