This thesis sets out to assess the stiffiiess of typical fin plate steelwork connections. The classification of joints as pinned, semi-rigid or fixed is described and the different models of moment-rotation relationship are explained. Eurocode treatment of steelwork connections is assessed with particular emphasis on joint stiffness. Procedures for the design of fin plate connections are set out and an example presented and a spreadsheet developed. Tests on a number of fin plate connections were carried out in the Heavy Structures Laboratory, to determine the moment rotation characteristics. The finite element software LUSAS was used to analyse the fin plate connections and the results are compared with the results from the Laboratory tests. It is concluded that fin plate connections should be considered to be effectively pinned.
