Design of composite beams using precast concrete slabs (P287)
This publication presents design guidance on the structural interaction and detailing of precast slabs with supporting composite beams or slim floor beams. Load-span tables for initial sizing and a worked example are included. Guidance is based on both UK and European codes. Precast concrete floors are widely used in building construction. There is little detailed design guidance on their application in steel framed buildings. There is an increasing number of composite frames and slimfloor constructions where the precast slabs are designed to interact structurally with the steel frame. The use of hollow core or solid plank precast units offer benefits in term of cost (the long spanning capabilities of the precast slabs lead to fewer secondary beams) as well as the advantages offered by composite construction. This publication provides guidance on the design of steel beams acting compositely with precast concrete slabs in multi-storey buildings. The design basis is generally in accordance with BS 5950-3, supplemented by recommendations from Eurocode 4 and data from tests; it applies to hollow core units of 150 to 260 mm depth, and to solid precast planks. Small-scale push-out tests, and earlier composite beam tests, have established reduction factors for the design resistance of welded shear connectors as a function of the gap between the ends of the precast concrete units, and the amount of transverse reinforcement provided.

The guidance also emphasises the importance of the design of the steel beam in the non-composite construction stage, where out-of-balance loads can occur during installation of the precast concrete units. A step-by-step design procedure is given for composite beams using various forms of precast concrete units, with or without a concrete topping. This is supplemented by a fully worked design example for a composite beam in a 15.8 m x 7.2 m grid, and a series of design tables for concept design.
