A trapezoidal concrete dam is 25 m high. The upstream face is vertical and the water is flush with the top,which is 3.5 m wide. The coefficient of friction between the base of the dam and the foundation is 0.70.If it is required to have a factor of safety of 3 for overturning and knowing that specific gravity of concreteis 2.4, determine the following:a. Required width of the baseb. Factor of Safety against slidingc. Pressure at the heel and toePs: Neglect hydrostatic uplift.

For a simply supported prestressed concrete beam, compute the stress in the top fiber at the centerline. Properties of the bearn are: Width of the bearm, b: 326 mm; Depth of the beam, d: 471 mm; Eccentricity of the beam, e: 157 mm; Prestressing Force, P: 739 KN; Superimposed Load, w: 6 KN/m; Length of the beam, L: 9 m. Stress is in unit MPa. Write only the value of your final answer. w (including selfweight) P. P.
A prestressed concrete beam of section 250 mm wide by 600 mm deep is used over an effective span of 10 m to support an imposed load of 8 kN/m. If the unit weight of concrete is 25 kN/m³, find the magnitude of: (a) the concentric prestressing force necessary for zero stress at the bottom fibre at the midspan section when the beam is fully loaded. (b) the eccentric prestressing force of the tendon located at 200 mm from the soffit of the beam that would nullify the flexural stress due to the combined dead and imposed load. (c) Discuss the implication of the results in (a) and (b) above.
At the limit state of collapse, an RC beam is subjected to flexural moment 200 kNm, shear force 20 kN and torque 9 kNm. The beam is 300 mm wide and has a gross depth of 425 mm, with an effective cover of 25 mm. The equivalent nominal shear stress (t) as calculated by using the design code turns out to be more than the design shear strength (T) of concrete, The equivalent shear force and equialent flexural moment ?
A 250mm x 600mm 10m-simple span prestressed concrete beam has a uniformly distributed dead load of 8.50 kN/m in addition to its weight. The tendons are placed 100mm from the bottom of the beam and is subjected to initial prestress force of 1880 kN. The beam is used to carry a live load of 25 kN/m. If the unit weight of concrete is 24 kN/m3, determine the stress at the bottom fiber of the beam at midpan after 20% of the losses at its final stage CS Scanned with CamScanner
Calculate the total stress in the given beam due to prestress only. A rectangular beam 200 x 300 mm is prestressed with 15-6 mm diameter wires located at 65 mm from the beam soffit and 2-6 mm diameter wires located 25 mm from the top of the beam. The prestress is 1000 MPa with a length of 8 meters.
A cantilever beam, 90 mm wide by 250 mm high and 7 m long, carries a load that varies uniformly from zero at the free end to 1300 N/m at the wall. Compute the magnitude of the maximum flexural stress. Answer must be in MPa.
