Abstract:
In the design of many building structures for ultimate states the use of interaction
equations is quite common. Despite this there is still a need for more advanced and
flexible equations which consider all forces in space. Steel l-section members are
often employed as beam and column elements for both structural and aesthetic
reasons. The purpose of this thesis is to develop, in principle, the interaction
equations for l-sections and verify it using experimental and finite element
techniques. Two types of interaction equations are developed. One is the
approximate approach in which single equation interaction equation is developed for
biaxial bending moment and bimoment. The yield surface developed based on this
approach fills the large gap in the previously developed yield surface. Second is the
exact solution in which interaction equations for biaxial bending, biaxial shear, axial
force, uniform torsion and bimoment are developed. This exact solution results in an
improved, closed, continuous and convexed yield surface for an l-section. These two
types of interaction equations are verified using a series of experiments and
numerically using finite element analysis using software LUSAS.
