    Abstract
  • In order to study the influence of shear deformation on the bending deformation of composite beams with steel corrugated steel webs, trigonometric series solution was introduced to simulate the deformation of the components (web and flange) of the beam according to the plane-section assumption, and a theoretical model was presented on the basis of the principle of minimum potential energy. Then, analytical solutions and respective simplified forms were derived for simply supported and cantilever corrugated steel web girder cases under uniform distribution and mid-span concentrated load. Furthermore, a limit value of depth-span ratio was suggested to estimate the influence of shear deformation with regard to magnifying coefficient of deflection. Validity and usability of the analytical solution and the model were determined by the finite element method. The results show that the presented method has advantages of ease in boundary condition and deduce, high reliability and universal applicability, and can be referred for deflection design of steel corrugated steel web beam.
