The development of a new design guide for standard steel/concrete composite connections is described in detail. The benefits of using composite connections are discussed in the introduction with the emphasis placed on the savings associated with reduced beam depths, improved serviceability, improved architectural and design freedoms, savings in service and cladding costs and weight savings.The scope of the new method presented in this paper is limited to partial strength composite connections in braced frames, where the connection between the beam and column is of the flush end-plate type. The design guide also covers partial depth end-plate beam to beam connections but these are not discussed here. The design guide can be used for both manual and computer-aided design and detailing, and a full description of the design method is given. The design method is in the form of an easy to use step-by-step check list for a set of standard composite connections which is based on the latest design theories and practical aspects associated with current fabrication and erection techniques in the UK. These design checks are supplemented by quick look up tables and worked examples for each connection type.Finally, the method is compared with available experimental evidence for practical composite connections and it is concluded that the new method is safe and gives reasonable estimates of strength.
