Solution for the Shear Lag Problem of U-Shaped Beam by Three Bar Stimulation Method

Abstract:

three bar stimulation method was adopted to build a differential equation about shear stress for U-shaped beam slab. Relative stress formula for simply supported beam which is subject to uniform load and concentrated load was obtained by solving and deducing differential equation.In order to compare with general beam theory simply,this paper introduced a concept of shear lag coefficient. Finally,combined with a actual example,after compared with measured value and other theoretical results,final result was satisfactory.
