This report is concerned with the development of Load and
Resistance Factor Design Criteria of composite beams.
Resistance Factor pie of LRFD Method could be obtained from
statistical study of ultimate strength of composite beams
under positive moment.
Its values were: pie=0.081 in the case of solid slab, pie=0.871
in the case of deck slab.
As the result, we could find out that pie=0.85 would be
reasonable for serviceable safty.
