= H.W No.1: A pretension beam is to carry a superimposed dead load of 8.75 kN/m, self-weight of 9.46 kN/m and service live load of 175 kN/m an a 16.8 m simple span. Asymmetrical I-section with b=0.5h will be used. Flange thickness hf 0.2 h and web width bw = 0.4b. The member will be prestressed using strands having fpu=1862 MPa. Time dependent losses are estimated at 20% of Pi, fe=34.5 MPa, fei=20.7 MPa. Using straight strands, find the required concrete dimensions, prestress force and eccentricity. Select on appropriate No. of 12.7 mm; 7 wire strand (92.9 mm² for each strand) 0.5h h <0.4b 0.2h 0.2h
