21 Not correct things in European prestandards ENV 1993, ENV 1999 Some coefficients C i are incorrect (e.g. instead of C 1 =0.411 it is used C 1 =1.73,etc.) No information is given about used torsion boundary conditions (k w =1) in the cases of end moments No information is given about used lateral bending boundary conditions (fixed is left beam end)
22 Not correct things in European prestandards ENV 1993, ENV 1999 No definition of M cr location (location is in middle of span) Influence of torsion stiffness and warping stiffness are not taken into account in calculation of C 1 coefficients For beams with nonsymmetric crosssections under nonsymmetric bending end moments are C i coefficients incorrect

PURE BENDING. If a simply supported beam carries two point loads of 10 kn as shown in the following figure, pure bending occurs at segment BC.

Notes for Strength of Materials, ET 00 Steel Six Easy Steps Steel beam design is about selecting the lightest steel beam that will support the load without exceeding the bending strength or shear strength
7 TRANSVERSE SHEAR transverse shear stress longitudinal shear stresses
7 TRANSVERSE SHEAR Before we develop a relationship that describes the shear-stress distribution over the cross section of a beam, we will make some preliminary remarks regarding the way shear acts within
