M2: based on right hand rule , thumb in direction of axis-2 and the shell will bend about axis -2 and consequently the resisting rebars will be parallel to axis-1. Thanks @Parash
So am i wrong here then ?
@@civilconst yes in that particular point .
can you share a proper example or video to understand ?? thanks
@@civilconst YOU tell correct M11 and M22 but bar placing is not parallel it's perpendicular to axis think like beam,
@@suhaibkhan7356 I think for m22, deflection will occur parallel to direction 2, so rebar shall be provided parallel to axis 2 to resist that deflection.
Won't the first number of the shear force be the number perpendicular to the shear surface? For example, wouldn't the shear force shown as V23 be V13?
M11 is moment acting on the positive and negative faces of shell in axis 1 direction! This means that it's rotating about axis 2. This video will confuse people, BIG mistake.
very nice explanation, thanks
Glad it was helpful.
Dear, u ve wrong concept regarding defining the moments n Rebar placement. Kindly correct urself
Please correct me. I would love to know your part of the concept as well.
Rebar placing is not correct
Please correct it then. Do share your view.
Thanks
M11 is the moment about local axis 2. Hence, the rebar for M11 will be provided in the direction of local axis 1. Likewise M22 is the moment about local axis 1 and the rebar for this moment will have to be provided in the direction of local axis 2.
