1. Draw a Magnel diagram for the 'T' section shown in Figure Q1 if the section is to resist moments of 100 kNm and 200 kNm at transfer and in service respectively. Allow for 15% loss of prestress in service. Compressive stress at transfer: 12 N/mm2 Tensile stress at transfer: 0 N/mm2 Compressive stress in service: 20 N/mm2 Tensile stress in service: 1 N/mm2 700mm 300mm Figure Q1 200mm 500mm 1.
