Question

1. A plain concrete beam having a trapzoidal section, symmetrical about a vertical axis, has a width of 300mm at the extreme compression fiber and a width of 200 mm at the extreme tension fiber. If the overall depth of the beam is 600 mm, determine the bending moment that causes the section to crack. Use a tensile strength of ft = 3 MPa. For this cracking moment, what is the maximumm bending stress in the extreme compression fiber? (30 pts)

Step 1

The beam has a trapezoidal cross-section with the following dimensions: - Width at the top (compression fiber), \( b_1 = 300 \) mm - Width at the bottom (tension fiber), \( b_2 = 200 \) mm - Overall depth, \( h = 600 \) mm Show more…
