QUESTION 2 A simple 5 storey building is to be constructed in Adelaide. Use the details provided in Figure 2, Figure 3, and Table 3 to respond to the following questions. a. Calculate the dead load and live load per area of the floor. The floor dead load consists of the floor weight plus a superimposed dead load for the wall partitions. 7 marks b. In the second floor beams, determine the maximum moment and maximum shear for beams A4-B4 and B4-C4 due to live load only. Also, in no more than 50 words, compare and discuss the maximum moment and shear of the two beams. 10 marks c. Calculate the deflection of beams A4-B4 and B4-C4 in the Second floor due to the dead load only if a cross section of 460 UB 82.1 is used. Also, in no more than 50 words, compare and discuss the deflection of the two beams. 6 marks d. In no more than 100 words, explain why I-shaped sections are usually used for beam members and also explain which part of an I-shaped section resists shear and which part resists moment. 5 marks e. Column i. Determine the force in columns A2 and B2 at the First Floor and Second Floor, due to dead load only 6 marks ii. In no more than 50 words, Compare and discuss the loads of the edge (A2) and internal (B2) column. Also, in no more than 50 words, compare and discuss the loads of these columns in the Second and First floor. 6 marks Your calculations are to be based on the following design assumptions: Ignore the weight of the beams and columns. Beams are simply supported at their ends The building has N levels First Floor Second Floor Nth Floor The loads on all floors including the roof (which is the ceiling of the Nth Floor) are the same All beam-column connections are pinned connections The slab design is a One-way slab in the Y-axis direction ● Assume Esteel = 200,000 MPa ● If required, make further design assumptions and justify with suitable explanations.
