PROBLEM 3. Compute the minimum safe steel area at the fixed end of the propped beam in Figure 3. The beam is loaded in its entire span by uniformly distributed deadload and liveload of intensities 5 kN/m and 8 kN/m, respectively. The beam also carries a concentrated deadload of 10 kN and a concentrated liveload of 15 kN, both placed 2m from the propped end (See Figure 2). Due to architectural conditions, the beam dimension is limited to 300mm by 500mm. Use f.'= 34.5 MPa and f, = 414 MPa. Use effective depth, d = 440mm. P. (kN) w. (kN/m) 2 m L= 6m Figure 3
