A singly reinforced beam with a rectangular cross-section of 400×600 mm spanning 5 m with an applied dead load of 18 kN/m and a live load of 9 kN/m. It uses 32 MPa grade concrete and reinforced with 3N28 bars. The effective depth, d can be taken as 550 mm. i. ii. Calculate the immediate (short-term) and the total (short + long term) deflection using the simplified method - you need to use Bischoff's equation (the equation 8.5.3.1(1) in AS3600-2018) to calculate Ief. [30 marks] [15 marks] Check the deflections using the deemed to confirm method. Compare the results from simplified method and deemed to confirm methods (no more than 100 words) [05 marks] Note: Short-term can be taken as-56 days and long-term can be considered - 30 years. Consider a tropical environment and assume the top surface of the beam is not exposed to drying. The beam is a part of a domestic building floor system.
