CFVR5224 - Time-dependent losses. Uncoupled calculation type (ACI)
The model is a prestressed beam with a length of 16 cm
The beam is made of C40/50 concrete and the tendons are made of Y1960S3 steel.
The section is rectangular 1 x 0.8, with reinforcement of s500 steel.
The aim of the example is to verify the calculation of prestressing losses for active tendons.
