Nonlinear load-displacement analysis of structures having members with non-warping cross-section
Solid or hollow reclan~lar and circular crosssection members are most extensively used in medium and small size steel structures. Such crosssections are non-warping cross-section. They are extensively used because of their strength and the ease to assemble. The governing differential equations and the corresponding stiffness equations for such members are derived. The loaddisplacement and stability characteristics of such members are investigated. The structure deformations are also indicated. Such knowledge will be very helpful for engineers who are involved in the construe/ion of such structures.
