EFFECTS OF DEAD LOADS IN STATIC BEAMS

This paper attempts to clarify the varying deterrent effect of dead loads for elastic beams. The governing equation of beams, including the effect of dead loads, is proposed, and then, based on numerical calculations by the Galerkin method, the existence of the varying deterrent effect of dead loads for simply supported beams and fixed beams is proven for static beams. Key physical factors governing the varying deterrent effect on static live loads are represented from the closed-form solution, which is derived by solving analytically the governing equation, including the effect of dead loads by means of some assumptions. The proposed solution is proven to be exact by comparing it with the numerical results using the Galerkin method. A method that reflects the effect of dead loads on live loads is illustrated by an example.
