A simply supported high strength concrete beam of rectangular cross-section (b x D), {SHOWN IN THE FIGURE), supports uniformly distributed dead and live loads of intensities 'p' and 'q' per unit length respectively. The beam is prestressed by a straight tendon carrying a prestressing force P at an eccentricity 'e'. Show clearly and neatly the stress distributions, through the beam depth, due to eccentric prestressing, dead and live loads at a cross-section where maximum stresses Occur. DH 761 p, q per unit length DP

A rectangular reinforced concrete beam has a cross-section dimensions b=400mm andoverall depth h= 800mm. The beam as shown in the image below carries asuperimposed dead load of 12 kN/m (excluding the self-Weight of the beam) andspecified live load of 20 kN/m. The beam has a compressive strength of 30Mpa andreinforcement yield strength of 400 Mpa a) What is the self weight of the beam? b) What is the modulus of elasticy and yeild strain of reinforcement

For a simply supported prestressed concrete beam, compute the stress in the top fiber at the centerline. Properties of the beam are: Width of the beam, b: 222 mm; Depth of the beam, d: 396 mm; Eccentricity of the beam, e: 177 mm; Prestressing Force, P: 541 KN; Superimposed Load, w: 8 KN/m; Length of the beam, L: 11 m. Stress is in unit MPa. Write only the value of your final answer. w (including selfweight) 000
