The dependence of the deflection of the rod of a statically exterior indeterminate truss on the number of panels

Аннотация

A flat statically determinate symmetrical construction consisting of a crossbar and two lateral support trusses is loaded over the nodes of the lower belt by a uniform load. The structure has four supports, one of which is fixed, the other are movable. To derive the required dependence, we apply the induction method and special operators of the system of symbolic mathematics Maple. To calculate the deflection, the Maxwell-Mohr’s formula is used. Two variants of supports of the truss are considered.
