Abstract

This paper develops a method by which the stresses in the component parts of a solid web beam may be computed when the dimensions of the web thickness, beam height, and distance between stiffeners are such that the web does not go into the wave state immediately upon applying a small load. The stress in the web itself is calculated by a consideration of the buckling load of the web. The load in the stiffeners and flanges is computed by assuming an effective width of sheet as acting with them. This effective width is obtained by a consideration of the buckling properties of thin sheet in shear.

The results are in the same form as the familiar Wagner beam equations except that certain terms must be modified and corrections made. The results herein obtained are not to be considered as superseding the Wagner Equations as derived in Ref. I, but supplement them to take care of cases out of the range of the Wagner assumptions.
