1- The T-beam is made from concrete having a specific weight of 24 kN/m3. Determine the dead load per meter length of beam. Neglect the weight of the steel reinforcement. (20 Points)

2- The school building has a flat roof. It is located in an open area where the ground snow load is 0.68 kN m2.Determine the snow load that is required to design the roof. Use Ce=0.8, Ct=1.0, & Is=1.20.

(20 Points)

3-The steel framework is used to support the Reinforced stone concrete slab that is used for an office. The slab is 200 mm thick. Take , a = 2 m b = 5 m. Hint: b/a=(5/2)m=2.5m. Also, use Concrete Density=23.6 kN/m3 and Live Load for Office=2.4kN/m2.

a)So it is a _______ Way Slab.(4 Points)

b) The dead load due to weight of concrete slab is--------kN/m(4Points)c) The live load for an office is ----------kN/m(4Points)d) Total Load DL+LL is-------kN/m(3 Points)e) Show loading that acts along members BE and FED.(5Points)

4- Determine the force in members FAG, FAB, FBF &FBCof the roof truss shown below. The dimensions and loadings are shown. State whether the members are in tension or compression. (20 Points)Hint: Use the method of joints. Assume FBG=3.0kN
