Question

2. Figure Q.2 shows the section of a symmetrical prestressed concrete beam in which the eccentricity of the tendons is e mm, the cross-section area is A x 10 (mm2), and the 2d moment of area about x-x axis is Lu 10 (mm). (50%) Figure Q.2 e106.1 mm xx 1611 240 a. Calculate the maximum allowable prestressing force if, at the prestressing stage, the allowable stresses are 1 N/mm2 tension and 20 N/mn2 compression. What applied moment can then be resisted if the allowable stresses under load are zero tension and 20 N/mm compression? b.
