Notes:<br />
1. SDM = Structures Design Manual published by Highways Department.<br />
2. <strong>The</strong> basic concrete data for estimation:<br />
(a) Concrete Grade 60 (i.e. Fcu = 60 MPa.<br />
(b) Instantaneous Elastic Modulus = 30200 MPa (from Table 22 of SDM).<br />
(c) Design uni-axial compression stress at SLS = 26.8 MPa (at 1518 micro-strains).<br />
