Book Description
A theory is presented for constructing loadcreep deflection curves for beam-columns at any specified time. The stress-strain-time relation for the material is assumed to be represented by an isochronous stress-strain diagram approximated by an arc hyperbolic sine curve. A program has been written for the IBM 650 digital computer to calculate points on moment-curvature curves for a general I-section. The theory uses these curves and the successive approximations procedure by Newmark (Proc. Am. Soc. Civil Engrs., 68:691-718, 1942). The experimental part of the investigation included tests of rectangular- and T-section beam-columns made of 17-7Ph stainless steel and tested at 972 F. Several slenderness ratios were c nsidered. The beam-columns were subjected to a constant axial load located either at the centroid of the section or at an eccentricity of 15% of its depth and to a constant transverse load at midspan of sufficient magnitude to produce a linear elastic bending stress when acting alone of 0.50.

Book Description
A theory was presented for constructing the load-deflection relation and for determining the collapse load of a column having any known end condition. A trial and error solution was required which used interaction curves and assumed that the inelastic column assumed the shape of a sine curve. For time independent inelastic deformamation, constant depth of yielding interaction curves were used. For time dependent (creep) inelastic deformation arc hyperbolic sine interaction curves were used. The experimental part of the investigation included tests of rectangular section columns made of 17-7PH stainless steel and tested at room temperature and at 972 F. Several slenderness ratios were considered, and the columns had end conditions which were either fixed, equal and opposite end eccentricities, or unequal end eccentricities. Good agreement was found between theory and experiment. (Author)

Book Description
If the inelastic deformation can be considered time independent, a choice has to be made between an elastic and an inelastic solution. A study was made of the effect of several variables on the ratio of the load necessary to produce a specified inelastic deformation to the maximum elastic load. If the inelastic deformation is time dependent (creep), the only choice is an inelastic solution. (Author).
