Hi there, I having a problem understanding the design output in Etabs in a RC structure. For a given beam concrete design check, i am getting the following results in a certain beam section: 1- for Longitudinal reinforcement: TOP= 1.5 in2 BOTTOM= 0.9 in2 2- Shear reinforcement(stirrups): 0.3 in2. 3- Torsion reinforcement:A- 0.4 in2 B- longitudinal reinforcement= 2.17 in2 my questions are: A- For the stirrups should i go with the shear requirement since its greater or should i add the shear+torsion requirements and design the beam stirrups accordingly? B- For the longitudinal reinforcement, should i go with the Torsion requirement since its greater than the flexural requirement or add both Torsion + flexural requirement?I try to solve this in a way that is-From etabs shear,moment,torsion results after manual calculation I get torsion longitudinal rebar,Al which is much less than torsion output which we get from Etabs Concrete results.The screen shoot is given below. guys your help is much appreciated, i can't move on with my project until the above points are covered. thank you so much in advance and may god bless you.

even though all the sections is right the beam keeps on failing . i changed the torsional coffiecient to 0.01 . removed the load but its of no use it keeps failing giving an error shear and torsional coffficient exceeds.i have attached the model . thank you for the help SHIVA KUMARI.EDB
