dear all,
i have some questions and i am hoping to find some answers from you kind people.
1) when we use doubly reinforced beams how can be obtain economy be controlling ceiling height ?
2) where do we use bar curtailment and bent up bars in beams because there are not ACI provisions related to bar curtailment (as far as i know)
3)i have seen examples in books they calculate steel area for beams and they provide combination of different dia bars to satisfy that area why they do it because they can satisfy same area using same dia bars ?
4)which design method Etabs uses. LRFD or ASD?
5) how do we design the hanger bars. what is ACI provision for it?
6)where do we use inclined stirrups in beams ?
7) how the longitudinal reinforcing can be used as shear reinforcement ?
Thank you all in advance. Looking forward to your responses.
