Research has shown that the cost of a frame structure can be reduced by considering the semi-rigid behaviour of the joints between the beams and the columns. Tests were performed on 18 steel joints and 38 composite joints, allowing the determination of deformability components of a semi-rigid joint with cleated connection. On the basis of the test results, a mathematical model of the joints' behaviour was developed which could calculate the moment-rotation curve of a composite joint with cleated connection. A new finite element, taking into account the joints' actual behaviour in terms of connection and shear deformability, was introduced. This was then used, in a parametric study of braced and unbraced structures, to find the conditions for concentrated joint deformability in a single flexural spring. Simplified methods of designing steel structures with semi-rigid joints are presented and a cost comparison between semi-rigid and traditional design is described.
