Abstract: The paper describes a nonlinear analysis that can be applied to study the strength and behavior of stressed‐arch frames. The unique feature of the structural system is the way the arches are erected without the use of ...

Abstract: In the literature, the symmetry of the element tangent stiffness matrix of a spatial elastic beam has been a subject of debate. The symmetry of the tangent stiffness matrices derived by some researchers are tenuously ...

Abstract: For a framed structure that is subjected to bifurcation buckling, it may be useful to trace its secondary equilibrium path to gauge its sensitivity to geometric imperfections or to study the nature of load shedding from ...

Abstract: There have been controversy and uncertainties surrounding the rotational behavior of conservative internal bending moments in three-dimensional frames. The two contesting representations of conservative internal bending ...

Abstract: The paper describes a test program performed at the University of Sydney on small-scale (15.25 m span and 4.62 m high) complete single stressed-arch frames subjected to simulated gravity (vertical) loading. The analytical ...

Abstract: This paper presents a corotational formulation of a spatial beam element for the purpose of 3D plastic-zone analysis of steel frames composed of compact tubular sections and open sections with no significant torsional ...

Abstract: Stressed-arch frames are characterized by a posttensioning procedure that is used to erect the frames from an assembled configuration at ground level to a final erected shape. During the erection process, the top chord ...
