ACI-318-05 (Section 11.6.3a) û Torsional Moment Strength
ACI-318-05 (Section 11.6.3a) û Torsional Moment Strength
(OP)
Hello Fellow Engineers!
Anybody can suggest solution and practical ideas if the stresses in Torsion + Shear exceed the limit by the Code stated above without increasing the section of the concrete beam?
Your comments and suggestions is really appreciated. Thanks guys....

Those limits are pretty high. I wouldn't exceed them.

Here's the forces for your checking:
Beam section/dimension is limmited to b=400mm H=700mm
Mu = 795kN.m
Vu = 460kN
Tu = 180kn.m
Fc' = 40MPa
Fy = 460MPa
Fyt = 420Mpa

Thanks Cliff234, i'll try to reframe the structure in a way to reduced the stresses.

Please answer PUEngineer's question. He (and I) are suspicious as to what kind of torsion you have. If you would describe the structure or show us a plan of the structural element in question, we could assist further.

Since it is compatibility torsion, i changed the torsional modifier (J) to 0.01 and got a smaller torsion effect. Am I going ryt for the solution? please advise. Thanks
