1. A structural system for replacing a standard I-beam having a weight per unit length, a depth in a load direction, and a width in a cross direction substantially perpendicular to the load direction, the standard I-beam including a standard top flange extending in the cross direction, a standard bottom flange extending in the cross direction and a standard transverse section extending in the load direction, the standard transverse section connecting a first standard central portion of the standard top flange and a bottom standard central portion of the standard bottom flange, the standard top flange and the standard bottom flange each having a standard thickness, the structural system comprising:
a monolithic I-beam having the characteristic cross-sectional shape, the depth in the load direction and the weight per unit length, the monolithic beam including
a top flange extending in the cross direction and having a top thickness in the load direction, the top flange being not wider than the width in the cross direction;
a bottom flange extending in the cross direction and having a bottom thickness in the load direction, the bottom flange being not wider than the width in the cross direction, at least one of the top flange and the bottom flange having the width in the cross direction, the bottom thickness being different from the top thickness, the top thickness plus the bottom thickness being equal to twice the standard thickness; and
a transverse section connecting a top central portion the top flange and a bottom central portion the bottom flange, the top flange, the bottom flange, and the transverse section being an integrated structure of unitary construction forming the monolithic I-beam; and
at least one shear stud coupled with the top flange.
