In both bonded and unbonded post-tensioning systems, the pre-stressing force is transmitted through the anchorages. Note that both systems during the jacking procedure are unbonded. Moreover if the tendon profile is curved, transverse forces the so called curvature loads are exerted on the beam. ...

Thanks to all for your reply After your replies and a closer look to my calculations, I believe that is a matter of relative stiffness. The hand calculation is based on Czerny tables. These tables assume rigid supports. For this assumption to be valid, the beams should be much stiffer than the slab. ...

Hello The last few weeks, I deal with the slab of a METRO station. It is a rectangular reinforced concrete slab of dimensions 110mx26m. The thickness of the slab varies from 0.6m to 1.0m. The slab will be simply connected to the perimetric diaphragm walls via dowels. No interior vertical elements ...

But I have to say that the codes in effect (Eurocodes, EN-1992) do not give specific rules or details about this case. Therefore as long as the embedment length requirements are satisfied any ...
