INELASTIC DESIGN OF LOAD CARRYING MEMBERS. PART II. THE EFFECT OF END CONDITIONS ON THE COLLAPSE LOAD OF COLUMNS

Abstract

A theory was presented for constructing the loaddeflection 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)
