“…Sakimoto and Namita [11] investigated the out-of-plane buckling of solid rib arches braced with transverse bars. By using the principal of stationary potential energy and Rayleigh-Ritz method, Pi and Bradford [12][13][14][15][16][17][18][19][20][21][22][23] proposed analytical solutions for the elastic bending and torsional buckling loads of circular arches with boundary conditions of hinged, fixed and in-plane elastic rotation constraints under concentrated forces, uniform compression and uniform bending. Dou et al [24] first proposed a method for solving the shear and torsional stiffness of truss arches, and derived an analytical solution for the buckling load of lateral bending and torsional instability of truss arches with fixed restraints under uniform compression and bending based on the energy method.…”

To date, scholars’ research on the stability behavior of the arch structure mainly focuses on solid–web section arches, steel tubular truss arches and concrete-filled steel tubular arches, but the stability behavior of the novel spatial grid arch structure, which integrates the characteristics of grid structure and arch structure, is not yet clear. Based on the Eye of the Yellow Sea pedestrian bridge project in Rizhao, China, the stability behavior of this large-span spatial grid arch structure was studied, in this paper, by the project’s structure design team. The project is a glass covered steel arch pedestrian bridge with a span of 177 m, a height of 63.5 m, an elliptical section with a long axis of 18 m, and a short axis of 13.5 m. The elastic and the nonlinear elasto-plastic stability behavior considering different initial geometric imperfections, was analyzed by the ABAQUS finite element model. The buckling modes and the full-range load-displacement curve of the structure were analyzed, and the stress distribution, deformation mode and overall structural performance during the whole loading process were analyzed. The effects of initial imperfections, geometric nonlinearity and material nonlinearity on the ultimate load-carrying capacity of the structure were studied. The stability behavior of large-span spatial grid arch structure was studied in this paper, which provides an important reference for the design and analysis of such structures.

“…Similar loading case is considered by ref. [9] which takes a radial central load into account to formulate elastoplastic buckling of arch structures, numerically. A different loading type, which is axial and end moment, is studied by Asadi et al [10] to investigate buckling behavior of both open and closed section beams.…”

The present study investigates elastic buckling behavior of open-section shell segments under action of a central radial load. A design parameter is expressed to characterize the influence of fillet radius on load-bearing capacity. A reduction factor equation is developed as a multivariate function of shell parameters, which evaluates the amount of decrease in load-bearing capacity of the structure caused by the corner fillet. In addition, an expression to predict limit load of the shell structure under clamped end conditions is introduced. Furthermore, a parametric study is performed to reveal the influence of fillet radius and radius-to-thickness ratio on the limit load as well as deformation patterns of the open-section shells. Results show that corner fillets have a significant effect on the limit load of the open-section shell segments under in-plane loading.

“…Several studies have reported on the elastic LTB of pinned arches/curved beams in uniform compression and bending. From the reported studies, some of the analytical studies include those by Timoshenko and Gere [11], Vlasov [12], Yoo and Pfeiffer [14], Rajasekaran and Ramm [15], Papangelis and Trahair [16], Yang and Kuo [17,18], Rajasekaran and Padmanabhan [19], Yang et al [20], Trahair [21], Kang and Yoo [22], Bradford et al [23], Pi et al [24], Bradford et al [25,26], Yang et al [27], and Pi and Bradford [28]. Some discrepancies exist among the reported studies.…”

This paper presents the effects of the several factors that influence lateral-torsional buckling on freestanding circular arches. The studied factors that attribute to the effects of lateral-torsional buckling include cross section type, included angle, slender ratio, imperfection, loading, and boundary conditions. From the reviewed studies, the misrepresentation of these factors to a certain extent may yield inaccurate results. Several studies and design codes have proposed different solutions to account for these factors in designs against lateral-torsional buckling for some structural elements. However, there were no studies reported on the out-of-plane lateral-torsional buckling of fixed circular arches made of structural aluminum channel sections subjected to central concentrated load. Therefore, there is a need for further research on the lateral-torsional buckling real behavior of fixed circular arches of structural aluminum channels.
