Does the effective flange width of the h beam satisfies the requirement of ACI code? Assume columns are 400 time 400 min P\'c = 28 MPc, l_y = 420 MPc, columns l_ = 40 mu r

Solution

a t-beam used in construction is a load-bearing structure of reinforced concrete wood or metal with a t-shaped cross section. the top of the t-shapped cross section serves as a flange or comression membeer in resisting comressive stresses. the web of the bea below the compression flnge serves to resist share stress and to provide greater seperation for the coupled forces of bending

the t-beam has a big disadvantage compared to an I-beam because it has no bottom flage with which to deal with twnsile forces. one way to make a aT-bea with a floor slab or bridge deck joining the tops of the beams.done properly the slab acts as the comression flange

A T-bea is a structural element able to withstand loads by resistance in the beam or by internal reinforcements. in some resoects, the T-beam dates bac to the first time a human formed a bride with a pier and a deck. after all a T-beam is in one sense , no more than a pillar with a horizontally bed on top or in the case of the inverted T-beam on the bottom
