Assalaam o Alliakum Everyone!
 
	ACI requires that for Special Moment Resisting Frames beam depth should satisfy this condition
 
	ln/d >= 4
 
	ln = clear span of beam
 
	d = effective depth of beam
 
	I have a beam of clear span 6' in my design which means maximum allowed d would be ln/4 (i.e. (6*12)/4 = 18") so h=21.5" (if c=2.5").
 
	But the shear on the beams is too much that I can't decrease its h less than 27" (d=24.5") otherwise my beam fails.
 
	Moreover, I can not increase width due to architectural requirements. I am stuck very badly.
 
	Can I neglect this provision and move on? 
 
	Any help would be much appreciated.
