Nettet🕑 Reading time: 1 minute The doubly reinforced concrete beam design may be required when a beam’s cross-section is limited because of architectural or other considerations. As a result, the concrete cannot develop the compression force required to resist the given bending moment. In that case, steel bars are added to the beam's compression zone […] NettetMethods are proposed for the computation of flexural strength of composite beams and for design of shear connectors based on limit states of plastic strength. Both fully and partially composite beams with formed steel deck or flat soffit slabs are considered. LRFD resistance factors are derived using a first-order second-moment probability analysis.
