Q1: Find the Maximum Uniform Live Load can be applied on the beam shown below, f= 400 Mpa, f=25 Mpa. Use the ultimate design method (singly reinforced section). WL=? Wp 3 kN/m (neglect Self'weight) 5 m Fig.(1) 270 mm 700 mm

Q// A rod is composed of an aluminum section rigidly attached between steel and bronze sections, as shown in Figure below. Axial loads are applied at the positions indicated. If P = 11 KN and the cross sectional area of each rod is 312.5 mm', determine the stress in each section. 4P Steel Bronze Aluminum P 609.6 mm 914.4 mm 762 mm

2/3 700 mm 1) A typical cross-section of a properly reinforced con-crete beam is shown in the figure below. The material properties are summarized below. Use an effective depth of 600 mm. 500 mm Given: fy = 400 MPa = 0.65 75% = 0.85 E = 200 000 MPa Y See the Table 1 f' 48MPa - Bar : 3-30M a) Is the beam properly reinforced/over-reinforced/ balanced Determine the factored moment resistance? b) Consider the beam section "a) "above. However, due to embedded items, the reinforcing is raised by 65 mm, such that the effective depth is reduced to 585 mm (Draw the new cross-section view). Find the factored moment resistance considering the new reinforcement layout. c) Comment on the effect of the change in reinforcement location on the moment resistance d) Refer to the beam section from Part "b" above. The same contractor reported that, due to some problems related to batching, the actual 28-day concrete strength is reduced by 10%. What is the new F'c? Find the factored moment resistance for…
