continuous beam and plane frame by slope deflection method and moment distribution method. Module –II Analysis of continuous beam and simple portals by Kani’s method, Analysis of two pinned and fixed arches with dead and live loads, suspension cable with two pinned stiffening girders. Module – III Moment Distribution The Real Explanation, And Why It Works Professor Louie L. Yaw c Draft date April 15, 2003 To develop an explanation of moment distribution and why it works, we ﬁrst need to develop some tools. These tools, concepts or pieces of information will be helpful to us as we create the explanation of moment distribution and why it

Shear and Moment Diagrams for Frames Example: Draw the shear and moment diagrams for the following frame: 4 k/ft. A B C 8 k 4 ft. 4 ft. 3 ft. 2 ft. CIVL 3121 Shear Force and Bending Moment Diagrams for Frames 2/4. Shear and Moment Diagrams by Superposition We have learned how to construct a moment CE371 Structural Analysis I – Moment Distribution Method examples Example 1: Using the moment‐distribution method, determine the moments at the ends of each member. Draw the moment diagram. Let E = 29,000 ksi. The moment of inertia of each member is shown on the figure above. Assume the joint at B is rigid, C is pinned, and A is fixed.
