Thank you for insights. Bracing action of planks is an important point but needs further research to establish exactly how much it may contribute in the compatibility with the beam under torsion. I mean it will be affected by the span lengths, presence of cast in situ structural topping or as...
Hi,
I have been thinking about the additional longitudinal reinforcement required for torsion specifically for a precast beam. Precast beams are often simply supported and resist eccentric loads owing to wide use of inverted L shaped or T shapes with unequal loads. The resistance to torsion is...
Hi, as pointed out by phamENG, the pinned connection will give higher moments in beams so higher resisting stiffness will be required. To add another perspective in case of lateral loads on the whole structure with pinned connections displacements of the overall structure shall increase. To...
Agreed with KootK. Shear strength of the bar should govern instead of tension. Nevertheless ACI recommends checking the bar for a minimum tension of 44 kN for integrity (ACI 318M-11 sec 16.5.1.3(b) - (for precast construction only),I would suggest checking the anchorage capacity of the bar for...
