Analytical calculation of the deflection of a beam truss with parallel belts

Аннотация

A planar truss with a diagonal grille and racks is loaded on the upper or lower belt. The required dependence of the deflection on the number of panels, the size of the truss and the load is obtained by induction on the basis of an analysis of a number of trusses with a consecutively increasing number of panels. The analytical capabilities of the Maple computer mathematics system are used, which make it possible to compose and solve recurrent equations. To determine the forces in the rods, the method of cutting out the knots is used. It is assumed that all the rods have the same rigidity.
