1.The 30 ft simple beam shown has lateral support spacing at 15 ft for its compression flange and consists of 50 ksi steel. the beam supports a gravity service dead load of 1.2 klf (includes beam weight) and a gravity live load of 3.4 klf. The loads are assumed to act through the e.g. of the section. Select the lightest available W33 section.
2.A short Reinforced Concrete column is 350mm x 350mm. It is required to carry an ultimate load of 1500kN and an ultimate major axis bending moment of 300kNm. Calculate the area of reinforcement required.
