Abstract
This report presents the results of an analytical and experimental investigation for the determination of the load necessary to produce a specified amount of inelastic deformation in members which are subjected to eccentric tensile loads at elevated temperatures for a specified time. Two different theories were used in analyzing the experimental data. The arc hyperbolic sine theory uses material properties obtained from an arc hyperbolic sine curve approximation of the stress-strain diagram of the material. The interaction-curve-moment-load-curve theory uses material properties obtained from two straight line approximation of the stress-strain diagram of the material. In the experimental investigation, tests were made on eccentrically-loaded T-section members made of 17-7PH stainless steel at 1000° F. The test members were subjected to an initial eccentricity of either 25 or 51 per cent of the depth. It was found that the deflection of the central section of each member could be accurately predicted by either theory. In addition to the present investigation, tension creep data was obtained from 6-in. gage length specimens of the 17-7PH stainless steel used in the rectangular-section investigation which was reported in Part VIII (Contract No. AF 33(616)-2753). A more reliable value of the modulus of elasticity of the material was determined. Theoretical moment-load curves, based on the new value for the modulus, were constructed and are compared with the experimental data. A discussion of these results is presented in this report. Since publishing Part IX (Contract No. AF 33(616)-2753), an error has been found in the analysis of the test data for the eccentrically-loaded T-section members made of type 304 stainless steel. The corrected data are present in this report.
