Abstract


The article presents the derivation and solution of the differential equation of the ultimate limit state of the wooden and reinforced concrete beam under the influence of negative atmospheric temperatures, as well as the results of studies of the effect of negative atmospheric tempera- tures on the stressed state and the size of the cross-sections of the composite beams made of wood and reinforced concrete, in auto road bridges obtained by the developed program of computer-aided design.
