Structural Engineering & Construction Situation 50 (PH)

PAST BOARD EXAM PROBLEMS Structural Engineering & Construction Situation 50 Given: Beam sections (b x h) for AD, BE, and CF (250 x 400 mm) Girder sections (b x h) for ABC, and DEF (350 x 600 mm) Dimensions: S = 3.0m, L = 6.0 m Concrete cover to centroid of reinforcements = 70 mm f'c = 20.7 MPa, fy = 275 MPa Loads: DL = 5.5 kPa (weight included) LL = 4.8 kPa (all spans) U = 1.2DL + 1.6LL Strength reduction factor = 0.75 1. Which of the following gives the critical design shear stress (MPa) in beam BE? (1.30 MPa) 2. Which of the following gives the shear strength, Vc (kN), provided by the concrete in beam BE? (63.8 kN) 3. The shear reinforcement of beam BE consists of two legs of 10mm diameter bars spaced at 150mm center to center. How much is the resulting shear strength, Vs (kN)? (95.05 kN) Credits: 1.
