Accounting Stiffness Nodes of Spatial Crane Structures
Abstract
The article is sanctified to the calculation of spatial metallic constructions case-insensitive assumptions about a presence in the knots of hinges. Terms at that subzero assumption gives an incorrect result (not in the margin of safety) are considered. The methods of calculation of such constructions are indicated and chosen on that ground the most rational variants of the weld-fabricated knots. A calculation chart over, to that faucet arrows are taken by c runners and methodology of calculation is indicated, is brought. Influences of all possible factors are considered, including initial tensions on the tense state, and formulas over, on that it is possible to define tension in knots and contiguous farms, are brought, and in points depending on inflexibility of knots.
