This document concerns the design of moment-resisting composite joints. They are beam-to-column or beam-to-beam joints that are designed so that reinforcement in the slab contributes to the resistance and the stiffness of the joint. The action of the reinforcement permits the frame to be designed as a semi-continuous or even continuous, even though the steel connection within the joint may be of a nominallypinned form. An introduction to composite construction for building frames and to the classification of joint behaviour is given. The flexural behaviour of composite joints is discussed, with reference to tests on full-size configurations; the influence of various components on the response is observed. A formal statement of the components relevant to composite joints is given. The evaluation of component characteristics is described, including transformations needed to permit nodal representation of joints in frame analysis. The document concludes with comparisons against some test results to demonstrate the suitability of the methods already described.
