- Аннотация: A schema of a statically determinate beam girder with a regular structure, which has two supports at the ends, is considered. The descending and ascending braces have different inclination angles. In the system of symbolic mathematics Maple, the analytical dependence of the deflection of the structure and displacement of one of the three movable supports on the number of panels is derived by induction. In the procedure for generalizing several solutions to the general case, the operators rgf_findrecur and rsolve are used to compose and solve recurrent equations, which are satisfied by the coefficients of the sought formula. Cases of kinematic degeneration of the structure are found for a certain number of panels, the corresponding schemes of possible speeds are given, and a static interpretation of this phenomenon is given
