Analysis of the deflection of externally statically indeterminate lattice frame, allowing for geometric variability

Аннотация

The lattice frame has four rod-type supports. The load is applied evenly over the nodes of the upper belt. The dependence of the deflection of the frame on the number of panels in the crossbar at a fixed number of panels vertically is obtained. To solve the problem, the Maple computer mathematics system is used. An inductive method is used to generalize a number of particular solutions to an arbitrary case. When calculating the deflection, the Maxwell-Mohr formula is used. For some values of the number of panels, the case of degeneration of the determinant of the equilibrium equations is observed.
