PPT-Shear Forces and Bending Moments in Beams

Chapter 13 Strengths Introduction Beams are members that carry transverse loads and are subjected to bending Any member subject to bending is referred to as a beam Beams considered in this course are limited.

Members that are slender (length dimension >> width dimension) and support loadings that are applied perpendicular to their longitudinal axis are considered beams. Beams develop internal shear force and bending moment that, in general, vary from point to point along the axis of the beam. 5.

ANALYSIS OF TWO-WAY SLABS WITH BEAMS. In this lecture the moments are determined by the direct design method for an exterior panel of a two-way slab with beams. It is felt that if you can handle this problem, you can handle any other case that may arise in flat plates, flat slabs, or two-way slabs with beams using the direct design method..
