WebApr 1, 2024 · The loss of prestress is considered when calculating the stresses of each BCCP layer under internal load. The result of the loss is approximately 15%, according to the specification CECS140:2011 . Therefore, the ultimate effective tensile prestress of the steel bars is f se = 0.72*f su *0.85. The process of BCCP from applying prestress in ...
