Physicomathematical model of calculating continuous beams with elastic yielding supports

Abstract

In this work there has been studied the rod system operation dependence on the action of external force effects. The system presents a multi-span continuous beam with elastic yielding supports. To identify the stress-strain state of the object under study, a precise analytical method of forces is used. The method of five moments is used as the resolving (canonical) equations. The final results are the parameters of the stress-strain state for a five-span continuous beam with variable compliance coefficients on 5 intermediate supports and an absolutely rigid left extreme support, deflections, bending moments, shear forces, and support reactions.Theoretical provisions and practical results can be used in the design of load-bearing beam structures in buildings and various engineering structures.
