The Composite Beam Design with Formed Steel Deck method utilises the combined strength of a steel beam and a concrete slab to carry loads more efficiently. The formed steel deck serves both as a permanent formwork during construction and as reinforcement for the slab in service. Following the AISC-ASD (Allowable Stress Design) provisions, this approach ensures that stresses in both the steel and concrete remain within safe limits under service loads, providing a balance between material efficiency and structural safety.
This Excel sheet automates the design process by calculating section properties, composite moment capacity, and deflection checks based on AISC-ASD requirements. It accounts for deck geometry, slab thickness, shear connector spacing, and live load deflection criteria, making it a time-saving tool for engineers. Whether for preliminary sizing or detailed design, it delivers quick, accurate, and code-compliant results without manual iteration.
