- Аннотация: A diagram of a statically determinate girder with a complex regular lattice is proposed. The induction method is used to derive the dependence of the truss deflection on the number of panels, truss size and load. Two types of symmetrical distributed load and a concentrated force load in the middle of the span are considered. To calculate the reaction of supports and forces in the rods in a symbolic form, the Maple computer mathematics system is used. The deflection and horizontal displacement of the movable support are calculated using the Maxwell-Mohr's formula. A number of truss solutions with different numbers of panels are generalized to an arbitrary number of panels. Linear asymptotics of solutions are obtained, graphs are constructed that reveal the features of the construction.
