Abstract:
This paper describes recent British tests concerned with catenary, or tensile membrane, actions, which may prevent local damage to a structure spreading to cause a progressive collapse. Reference is made to preliminry tests of structure, some of which indicated the considerable potentialities of such behaviour. More detailed tests studying the tensile strengths and ductilities of various components are described, as are experiments on floor strips with lost supports. Finally, possbile methods of predicting catenary resistance are discussed, although no general design guidance seems possible at this stage.
