A new approach to the analysis of three-dimensional framed structures whose prismatic members are interconnected by slab floors is presented. The method is illustrated by the computer program described. The structures are restricted to those of an orthogonal nature with rigid, interconnected elements. The method of solution is a stiffness matrix approach utilising a finite element formulation for the in-plane and out-of-plane action of the floor deck. A process of condensation is applied to the stiffness matrices to reorganise and reduce storage demands. A 'part-structure' condensation is employed floor by floor, making the process highly suitable for multi-storey structures. Several examples are given to illustrate the use of the program and to demonstrate its versatility. Also the wide range of results obtainable and the methods of presentation are given. The program is used together with one for a plane frame analysis and one for a rigid, orthogonal, skeletal space frame analysis, both of which are described in this volume, in order to investigate and compare the solutions obtained for the test frames described. Some results are presented for the investigation into the stiffening effect of the floor slabs on the bare frame. Also the use of three-dimensional sub-frames for the analysis of beams in a space frame is presented. The effect on the total structure behaviour of finite element mesh concentration for the floor representation is also demonstrated.
