Load And Resistance Factor Design For Shear In Buildings

Based on the American Institute of Steel Construction (AISC) specifications for load-and-resistance factor design (LRFD) for buildings, the shear capacity V u , kip (kN = 4.448 X kip), of flexural members may be computed from the following:


Stifferners are required when the shear exceeds Vu. In unstiffened girders, h/tw may not exceed 260. In girders with stiffeners, maximum h/tw permitted is 2,000/(Fyf)½ for a/h less than equal to 1.5 or 14,000/(Fyf(Fyf+16.5) )½ for a/h > 1.5, where Fyf is the specified minimum yield stress of the flange.

For shear capacity with tension – field action, see the AISC specification for LRFD.

i want the design of PEB for a span of 15-m and to a length of 25-m with 30-TON EOT @
5-m. clear ht of building 7-m bay spacing 5-m in end & side wall. 3-m concrete block
wall with windows and sheeting on top. Can you design the building pls.
