Problem 1: (30 points) (Pre-stressed Concrete Design and Analysis) A prestressed beam of a certain condominium was designed to have a rectangular section 300mm x 600mm deep and has a simple span of 9m. At the midspan section, the tendons are placed at 200mm above the soffit which carries an initial prestressing force of 1,110KN which ultimately relaxes to 880 KN. If the allowable stress in concrete in compression is 13.5 MPa and in tension is 1.4MPa, determine the safe moment it could carry and the superimposed live load that it could also carry. Assume concrete will not crack in tension.
