Paper describes in detail tests on I4 composite col-umns at the Talbot Laboratory of the University of Illinois which showed that the then existing and also the present code requirements were too restricted. Also describes and lists the tests on a large number of composite columns made at the National Bureau of Standards, the Armour Institute of Technology, the Lewis Institute of Chicago, ber of European universities. by Emperger, and a num-Result of the tests at the University of Illinois was briefly as follows: columns failed at an average stress on the concrete section with 1 percent of spiral hooping and stresses in the cast iron core from 38 500 to 44,900 psi and stresses in steel cores of from 34,400 to 36,800 psi.
