THEORETICAL AND EXPERIMENTAL STUDIES OF COLUMNS JOINT IN DIFFERENT DIAMETER TUBULAR COLUMNS : 2. EXPERIMENTAL STUDY : Column under Normal Force and Uniform Moment

Abstract

In the previous paper, we have reported about a theoretical study of columns joint in different diameter steel-pipe columns under normal force and uniform moment. This paper is experimental study of joint. Test specimens are different diameter steel-pipe short columns welded with joint ring. We add axual load and eccentric load to them. And we compare strain distributions and elastic deformations of them with theoretical values. In consequence, theoretical values approximate experimental them.
