The strut is supported by a pin at C and an A-36 steel guy wire AB. If the wire has a diameter of 5 mm, determine how much it stretches when the distributed load acts on the strut

Design a beam having a width of 330 mm and overall depth of 650 mm.The 8m simply supported beam is to carry a DL = 5  kN/m including self-weight and LL =10 -  kN/m. The top and bottom steel reinforcements are to be placed at 80 mm from the outermost fiber of the concrete. Use fc’= 25 MPa and fy = 390 MPa. a. Maximum factored moment due to the loadingsb. Maximum moment the for singly-reinforced beam could carryc. Stress of the tension steeld. Area of the steel reinforcements.

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.<
