A frame as shown in figure 2 is fixed at node 1 and 4 carries a uniformly distributed load of 114 kN/m on member 1 and a concentrated load of 80 kN on member 3. Using the stiffness method, determine (a) the rotations at node 2 and displacement at node 3, reacting forces at supports, and (b) (c) draw the deflected shape of the frame. Show the importance values in the diagram. Given, the modulus of elasticity, E of 200 kN/mm, moment of inertia of the section, I of 3.75 10 mm and cross-sectional area, A of 4476 mm for all members. 114 kN/m 6 m 3 2 4 FIGURE 2 3 m 80 kN 3 m 3 6 m
