What would be the average compressive strength of concrete if the load at failure of the 3 trials are 55, 100 kg, 54, 800 kg, and 55, 200 kg. Diameter of the sample is 6". о 30.6 MPа о 31.6 MPа о 30.1 МPа o 31.1 MPa

Determine the permanent deformation after 2 hours show all work

Subject reinforced concrete design solve p02

Required information For the concrete beam shown, the modulus of elasticity is 25 GPa for the concrete and 200 GPa for the steel. Take b=218 mm and d = 450 mm. Use an allowable stress of 12.5 MPa for the concrete and 140 MPa for the steel. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Using the area of steel calculated in part a, determine the largest allowable bending moment. The largest allowable bending moment is 96.06 kN-m.

8. A rigid pavement concrete slab is shown in the given figure. Determine the stress and also max. deflection due to corner loading h 10 in. k = 100 pci h 10 in, a = 6 in. 9. Repeat problem (8) for interior loading case as shown in the given figure: S k= 100 pci h = 10 in. k = 100 pci a = 6 in. a 6in. 10,000 lb %i 4₁ 10,000 lb 10. Repeat problem (3) for edge loading cases (Circular or semi circular) as shown in the given figure: 110,000 lb %c = ? D. ? e = ? = ? 11. A section of a highway with length of 10 Km was evaluated using the Pavement Condition Rating Methods. The existing distresses along with this section are presented in the given photos. The severity and extent levels of each distress are given with the photo of the specified distress. The PCR form rating is also given.
