BEAMS: SHEAR AND MOMENT DIAGRAMS (GRAPHICAL) (5.3) Slide No. 4 Shear Forces and Bending ENES 220 ©Assakkaf Moments in Beams Example 9 A timber beam is loaded as shown in Fig.The Three-Moment Equation for Continuous-Beam Analysis CEE 201L. Uncertainty, Design, and Optimization Department of Civil and Environmental Engineering Duke University Henri P. Gavin Spring, 2009 Consider a continuous beam over several supports carrying arbitrary loads, w(x). Using the Moment-Area Theorem, we will analyze two adjoining spans.We can find the external forces using the FBD of the entire beam. However we may also want to find out the internal forces (and moments) at different points of the beam. This will help us decide if the beam can support the applied load or not. To do this, we imagine two (or more) sub -parts of the beam as shown. Tuesday, November 17, 2009 10:53 PM

A continuous reinforced concrete beam shown in the figure is 15 in. wide and has an effective depth of 31 in. The factored loads are shown, and the factored uniform load includes the weight of the beam. Design the web reinforcement if = 4000 psi and fy = 60,000 psi. Stirrup Design Procedure fc′The central portion of the beam is in uniform compression and, providing the three lengths between restraints are equal, it is length B-C that will be critical because the equivalent uniform moment factor is 1.0. Examplesof theeffectof momentgradienton mLT 52. Beam (d) is subject to two point loads that do restrain the beam.BEAM DESIGN In order to be able to design beams, we need both moments and shears. 1. Moment a) From direct design method or equivalent frame method b) From loads applied directly to beams including beam weight or max Mbm = Wbm ln 2 /10 ACI 8.3.3 2. Shear what to use for loads? ACI 13.6.8 (see next page)

Bending moments in beams of reinforced concrete buildings was the FEM package used. Since practical use of FEM to design structures still demands intensive work to analyze and interpret results, analysis using grid analogy, which is a common approach often used in commercial software to design reinforced concrete

CALCULATION OF WIND AND EARTHQUAKE LOADS ON STRUCTURES ACCORDING TO ASCE 7 & IBC WIND LOADS Buildings and their components are to be designed to withstand the code-specified wind loads. Calculating wind loads is important in design of the wind force-resisting system, including structural members, components, and cladding, against shear, sliding,Chapter 5: Indeterminate Structures – Slope-Deflection Method 1. Introduction • Slope-deflection method is the second of the two classical methods presented in this course. This method considers the deflection as the primary unknowns, while the redundant forces were used in the force method.Shear Forces and Bending Moments Planar (2-D) Structures: All loads act in the same plane and all deflections occurs in the same plane (x-y plane) Associated with the shear forces and bending moments are normal stresses and shear stresses.

Solutions Manual to Structural Loads 2012 IBC and ASCE/SEI 7-10 CHap This Solutions Manual was developed as a companion to the Structural Loads: 2012 IBC and ASCE/SEI 7-10 textbook. To increase understanding of this material and for its most effective use, readers should study the Structural Loads textbook and reference theHere we display a specific beam loading case. Integrated into each beam case is a calculator that can be used to determine the maximum displacements, slopes, moments, stresses, and shear forces for this beam problem. Note that the maximum stress quoted is a positive number, and corresponds to the largest stress magnitude in the beam.Examples of moving loads include live load on buildings, traffic or vehicle loads on bridges, loads induced by wind and earthquake, etc. In the analysis, the moving loads can be modeled as varying distributed loads, a series of concentrated loads, or the combination of distributed loads and concentrated loads.
