### Chapter 7

1. 1. 11/18/2011 Jaydeep Patel School of Technology,7-1 Beams Members that are slender and support loads applied perpendicular to their longitudinal axis.7-2 1
2. 2. 11/18/2011 Forces are acting on the girder or on the beam due to supported loads over it. These forces are balanced by the reactions given by the walls or by the pillars to the beam or girder. Wall supports or the pillar supports provide reactions to the beam to keep the forces acting on the beam in equilibrium.7-3 Types of Beams Depends on the support configuration Simply Supported Beam: When both end of a beam are simply supported it is called simply supported beam Such a beam can support load in the direction normal to its axis.7-4 2
3. 3. 11/18/2011 Cantilever Beam: If a beam is fixed at one end and is free at the other end, it is called cantilever beam. Over-hanging Beam: If a beam is projecting beyond the support. It is called an over-hanging beam. The overhang may be only on one side or may be on both sides.7-5 Beam with One End Hinged and the Other on Rollers: If one end of a beam is hinged and other end is on rollers, the beam can resist load in any direction Propped Cantilever: It is a beam with one end fixed and the other end simply supported. Continuous Beam: A beam is said to be continuous, if it is supported at more than two points.7-6 3
