Inglis A: A Fully Rigid Multi-storey Welded Steel Frame

The most recent extension to the Engineering laboratories at Cambridge University has been designed with a fully rigid site-welded steel frame. The method proposed by the Joint Committee was used as far as possible but certain departures were made, mainly due to the use of high yield steel. The method involves (a) the plastic dcsign of the beams and (b) the use of limited substitute frames to determine bending momcnts in the columns, and both these features are present in the design. The stability of the columns was checked by the BCSA charts rather than by the tables given by the Joint Committee. Sample calculations are given to illustrate the working of the method and comparison is made with a sketch plastic composite design. J. Heyman, J.C.H. Finlinson and R.P. Johnson
