Prediction of the initial stiffness of ductile end-plate steel connections



Semi-continuous construction is a recognised basis for design of steel structures. Expensive full-strength and rigid joints are avoided, but the frame analysis needs to take account of the expected connection performance. Wind-moment frames are common examples of semicontinuous construction, for which standard end-plate connections have been developed. These are relatively flexible and therefore have significant influence on sway deflections. This paper presents a. method to determine easily the stiffness of such connections when one or two bolt-rows are in tension. This provides a basis for determining the sway of an unbraced frame, or estimating the serviceability of a braced one. The proposed method shows good agreement with tests on the standard connections and on similar forms of joint
