Calculus of a truss frame flexure

Mikhail Nikolaevich Kirsanov, Randy Cedric Razananirina


The statistically determinable flat symmetrical frame is fixed on four support rods and is put under load along the upper belt. It is given a formula for the middle point flexure. It is noticed, that for an odd number of panels along the frame height, independently from the panel number in width, the determinant of the nodes’ equilibrium system of equations, from which the forces in the rods, equals zero. The induction method is used for the general flexure formula for any number of panels in width for two panels in height. The flexure is calculated using the Maxwell-Mohr formula in Maple.
