Abstract: The sources of nonlinearities in the behavior of bolted steel connections are briefly studied, and a connection model is proposed. The model is used to demonstrate the nature of the nonlinear behavior of bolted connections, ...

Abstract: The assessment of reliability for framed steel structures is approached by the determination of limit state surfaces in load space. Surfaces corresponding to initial yield, plastic hinge formation and mechanism formation ...

Abstract: A general instantaneous or tangential stiffness matrix for a plane frame member is presented. Expressions in the form of integral equations are developed for members having axial forces and arbitrary material properties, ...
