A lot of fatigue cracks were reported in orthotropic steel deck (OSD) because the structure of OSD supported wheel load directly. Among them, many fatigue cracks at the intersections between trough rib and transverse rib were reported. Improved structures of the the intersections between trough rib and transverse rib were reported by many researchers. The purpose of this paper is to propose new structure of OSD that using Thread Rolling Screw at joint of trough rib and transverse rib instead of welding and confirming its fatigue durability by fatigue test. Two specimens were prepared. These differences are thickness of deck plate. After fatigue test, we drilled 40 mm diameter hole at upper deck surface and conducted magnetic particle testing to confirm development of deck crack. As a result, fatigue cracks developed at the connection between transverse rib and deck plate in existing structure while no fatigue cracks were detected in proposed structure.

“…The elastic lateral buckling of twin-arch ribs braced with transverse bars normal to the plane of the ribs has been studied by several investigators, including Ostlund (1954), Kuranishi (1961a), Almeida (1970), Tokarz (1971), and Sakimoto and Namita (1971).

“…While the magnitude of the asymptotic value depends on the properties of the bracing system listed above, the asymptotic value of the buckling load for a closely braced arch system can be obtained when D x ≥ 10b(B/R) or D z ≥ b(B/R), respectively (Östlund, 1954;Sakimoto and Namita, 1971). The flexural stiffness D z is less important except when the arch ribs have an open-profile cross section and the stiffness D x cannot be provided.…”

“…Hodges [10] studied the nonlinear in-plane deformation and bucking of rings and high arches under a hydrostatic pressure effect. 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.…”

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.
