Report on Structural Engineering in Germany. Discussion on Mr. John Mason's Paper

My first and most pleasant duty, gentlemen, is to express my sincere thanks to the members of this Institution for the honour they have done me in electing me their President for the coming session. I wish also, and most particularly, to tender to you, gentlemen, my personal thanks, and best wishes, with the hope that every one of you, who, as yet, has not been faced with the mixed joy of writing a presidential address, may have that task thrust upon him at no very distant date. Professor H. John Collins

Many investigators have published test results concerning the maximum strain capacity or extensibility of concrete in tension since Considere first stated his hypothesis that the extensibility of reinforced concrete was ten to twenty times greater than that of unreinforced or plain concrete; A resume of these early experiments on the cracking of concrete is given in a comprehensive paper by Dr. F.G. Thomas2, from which it is clear that the majority of workers strongly disagreed with Considere’s findings in that the strain capacity of reinforced concrete is approximately the same as that of plain concrete. Professor R.H. Evans
