Extracted text: The beam shown in figure below supports uniformly distributed dead and live loads. Based on the factored loads, envelopes of moments have been shown in the figure. The material properties are: f = 25 MPa and fy 420 MPa. Using 620 rebars, design the beam for positive and negative bending moments. 8.0 3.0 400 kN.m M, 220 kN.m |
