The semi-gantry crane in Figure 3 is gravitally and laterally loaded, as shown. Gravity loads: on the cross member a distributed load of 2k / ft on the BC part and a point load of 10k in E on the console beam DE. Side loads: A concentrated load of 40K at mid-span on the AC upright. You are asked: a) Using the Rotation method. determine the moments of continuity at the joints. b) Check the results of the moments of continuity by the method of Distribution of moments (Hardy CROSS). C) Draw the shear force (DET) and bending moment (DMF) diagrams 2 k / ft 10 k DE 10ft 40 k - 30 ft -30 ft- 10 ft El = constant E = 10,000 ksi1 = 3,000 in4 3 | 4
