Abstract:For Henan Provincial Art Centre, the deep cantilevered glass art wall, 40m high, employs a structural system of the single layer cable-net sub-structure combined with the major structure of in-plane intersecting weld pipe truss. Global stability of the major steel structure is considered to be a key controlling factor on structural safety. Nonlinear structural global buckling analysis is employed to design the structural overall stability performance. In addition, some strengthening methods are conducted to ensure that the whole structure is safe, based on the global stability performance by considering the factors, such as further analysis of the structural geometric arrangement, constraint condition of the key connections, structural initial geometric imperfection, elastic-plastic material of the structural components, load distribution, and computational load su-steps.

Keywords:structural overall stability; geometric nonlinearity; elastic-plastic material; buckling analysis; initial imperfection
