Lesson 20 The Moment- Distribution Method: Frames without Sidesway Version 2 CE IIT, Kharagpur
Instructional Objectives After reading this chapter the student will be able to 1. Solve plane frame restrained against sidesway by the moment-distribution method. 2. Compute reactions at the supports. 3. Draw bending moment and shear force diagrams. 4. Draw the deflected shape of the plane frame. 20.1 Introduction In this lesson, the statically indeterminate rigid frames properly restrained against sidesway are analysed using moment-distribution method. Analysis of rigid frames by moment-distribution method is very similar to that of continuous beams described in lesson 18. As pointed out earlier, in the case of continuous beams, at a joint only two members meet, where as in case of rigid frames two or more than two members meet at a joint. At such joints (for example joint C in Fig. 20.1) where more than two members meet, the unbalanced moment at the beginning of each cycle is the algebraic sum of fixed end beam moments (in the first cycle) or the carry over moments (in the subsequent cycles) of the beam meeting at C . The unbalanced moment is distributed to members and according to their distribution factors. Few examples are solved to explain procedure. The moment-distribution method is carried out on a working diagram.
