Use: D=9, H=4, J=2
The middle of the 5 m simple beam has a dimension of (150+ 50J) mm by (650 + 50D) mm. On that location, the beam is reinforced with 3-Ø28mm on the top and 5-032 mm at the bottom. The concrete cover to be used is 40 mm. The concrete strength of the beam is 27.6 MPa. The reinforcement (both tension and compression) used is Grade 50 (fy = 345 MPa). If the beam is carrying a total dead load of (35 + 5H) kN/m all throughout the span, 1. Determine the depth of the compression block. 2. Determine the ultimate moment capacity of the beam at the midspan. 3. Determine the uniform service live load (in kN/m) that the beam can sustain.
