5 pts A pre-stressed hollow core slab has property as follows: A = 109,867 mm2, St = Sb = 4,112,198 mm3. The slab is prestressed with 525 KN force at an eccentricity, e=35 mm below the centroid of the section. The weight of the slab is 3.61 kPa, SDL is 2.5 kPa, and live load is 2.8 kPa. The slab is simply supported on bearings at L=8.3m. Allowable stresses at service loads are 3 MPa in tension and 20 MPa in compression. Consider 20% loss of prestress at service loads. Determine the resulting stress at the bottom fibers of the slab at L/4 from the center of bearings, in MPa. Do not round-off during the course of solving. Answer in two decimal places. 150 mm 1.2m Next → < Previous
