F6-7. The beam supports a distributed live load of 1.5 kN/m and single concentrated load of 8 kN. The dead load is 2 kN/m. Determine (a) the maximum positive moment at C, (b) the maximum positive shear at C. B -2 m-

1. Loading on a frame.< A 3m 3m 3m E P (12KN) 1m 2m D A structure is manufactured from steel I sections, all of the same size. The members A-B and B-D are continuous sections, rigidly joined together at B. The strut C-E is connected to B-D and to the ground at E with frictionless pins. The connection to the ground at A provides full fixity in any direction required.< ← Ignoring the weight of the structure, calculate the reactions the foundations would need to resist. Draw sketch diagrams for the shear force, bending moment and deflection of the structure when the load is applied.<

Draw the influence line for the force in (a) member EFand (b) member CE.

2. Draw the influence line for the given truss members a. ILD of BC b. ILD of BF c. ILD of FE 60° 60 -20 ft- -20 ft- -20 ft-
