A reinforced concrete simply-supported T-beam , span length L 0 = 19.96 m , calculated span length L= 19.50 m. For concrete C35, f ck = 23.4 MPa , f tk = 2.20 MPa , and E c = 3.15×10 4 MPa. The environmental condition is type I, and the safety class is class 1 . The dimension of main beam section is seen in Figure . The class of mid-span section main rebar is HRB400 . Rebar section area A s = 6534 mm 2 ( 8Φ28+2Φ16 ) , a s = 111 mm , E s = 2×10 5 MPa , and f sk = 400 MPa. The lifting point of the simply-supported beam is set at the point away from the edge of beam , a =400 mm when beams are lifted. Flexural moment , M G 1 =498.62 kN · m , is formed in mid-span section because of beam self-weigh . Preliminary check normal stress of beam mid-span section in hoisting construction .
