This work is devoted to the development of parameters for evaluating the design solutions of ski jumps and the selection of the optimal design solution for material consumption for the K-60 ski jump in Krasnoyarsk. Research methods include the study and analysis of information sources, modeling and calculation. The initial data for the development of design solutions was the project documentation provided by the company "AMD", Yekaterinburg. The paper analyzes the practical experience associated with the design and construction of modern ski jumps, so the results can be used in the design of ski jumps. In the course of the study, the following results were obtained: 1. The parameters for evaluating the design solutions of ski jumps are formulated; 2. Five models were developed in the LIRA-CAD PC of the starting section of the in-run mountain with a span of 21 m with different static schemes of the superstructure; 3. Selective calculation and construction of nodal connections of two schemes was performed: with trusses with a height of 3m and a cross-rod spatial structure with a module of 1.5 m. The use of CRSS is in this case one of the optimal solutions with the lowest metal consumption. 4. An overview of the pies used for the construction of the ski jump landing mountain, calculation and construction of the optimal variant is performed. |
