direct designed of two way slab...is the beam need not to be desing

direct designed of two way slab...is the beam need not to be desing

direct designed of two way slab...is the beam need not to be desing

(OP)
as designing the two way slab by direct design method.. the beam carry most of the loads, thus the beams has its ultimate moments. the ultimate fuctored moment of the beam thats was derrived by the slab analysis should be used in designing the beam?

RE: direct designed of two way slab...is the beam need not to be desing

The Direct Design method is for the slab only.  You will have to find the loads on the beams separately, unless your beam is providing some restraint through torsion, such as negative moment at the end slab span.

thanks,
the 85% allocated moments if stiffness ratio and aspect ratio is equal or greater to 1.0 or 85 to 0 % if the value is lesser to 1.0 therefore is needing to be analized further?
