Calculation of the deflection of a decorative lattice of a truss with an arbitrary number of panels under the load in the middle of the span

Аннотация

The lattice of a planar symmetric statically determinate truss with two supports at the ends consists of separate panels. Each panel consists of nine rods forming a hexagonal contour. Thus, the lower and upper have a broken outline. The task is to obtain an analytical dependence of the deflection on the number of panels in the truss. To determine the forces in the rods, the Maple program is used, based on the method of cutting out nodes. The calculation of the displacement is carried out according to Mohr's formula.
