The layout of the stiffness matrix rod system
Scientific and technological progress in the construction and the resulting need to consult with new efficient methods of analysis of structures and their design leads to the need to understand the physical nature of the methods of calculation. The article outlines the basis for the formation of the transition matrix from the strains to stresses in the core systems. Considered different boundary conditions fixing rods and on the basis of these options provides a specific numerical calculation of internal forces diagrams of bending moments.
