The Structural Engineer, Volume 15, Issue 10, 1937
Mr. LEEMING, in presenting the paper, said that with regard to fixed-ended and free-ended conditions he was expressing only his own personal opinion. He wished it to be clearly understood that he did not mean to make any actual comparison; he preferred fixed ends, as compared with free ends, where no proper hinge was provided. In the case of certain bridges built by Hayden, in America, it appeared very doubtful that complete freedom had been achieved; if freedom were not achieved there was liability to some unintended stresses occurring in the leg of the frame and also near the points of fixation, which stresses had not been allowed for. That did not appear to be very good practice.
SIR,-In the issue of The Structural Engineer last August there appeared a discussion on Dr. Glanville’s paper “Strength Tests for Cement.”
T0 structural engineers, steel is perhaps the most fundamental material with which they have to deal: its strength, which term includes its remarkable properties of rigidity, and elasticity, makes it the building material best able to fulfil the many requirements of the profession. Not only is it the building material which will carry the greatest unit stresses, but its composition and capabilities are known definitely within narrow limits of accuracy. J. Gibson
