The question then arises about which time should be used to compute the creep coefficient. To solve this problem the following procedure is proposed Compute fg1,(t1, C1) with (t,t1) and 1. Compute fg1+g2(t2, 2) with 9(t,fe) and 2. Compute fg1 +g2+q(t3, 3) with 9(t,t3) and 3. Compute fq1(t2, 1) with (t,t2) and 1. Compute fg1+g2(t3, 2) with 9(t,t3) and 2 Compute the total deformation by using the following expression fg1 +g2+q,t fg1,(t1, 1) + fg1+g2(t2, 2) - fq1(t2, 1) + fg1+g2+q(t3, 3) -...

## Creep Coefficient Eurocode

Where t0 is the creep coefficient related to Ec , the tangent modulus, which may be taken as 1,05 Ecm as from Table 3.1-EC2 . Annex B of the Eurocode gives detailed information on the development of creep with time. Where great accuracy is not required, the value found from Figure 3.1 may be considered as the creep coefficient, provided that the concrete is not subjected to a compressive stress greater than 0,45fck tc at an age to. The values given in Figure 3.1 are valid for ambient...
