What is Experimental and Numerical Study on the Behavior of Single-layer Spherical Reticulated Shells Under the Combined Action of Temperature and Impact Load about?
The long-span spatial single-layer reticulated shell with welded hollow spherical joints is often exposed to impact loads and extreme temperatures, which may cause the failure of local joints and parts or the collapse of the whole structure. Research results have shown that the joints should be considered rigid when analyzing the mechanical properties of single-layer reticulated shells. The welded spherical joints in the actual form, however, are not entirely stiff, and the lack of stiffness of these critical joints may cause a dynamic failure of the reticulated shells. For this paper, through experiment and numerical simulation, the dynamic behavior of welded spherical joints and reticulated shells under the combined action of impact load and temperature is studied. Five sets of welded spherical full-scale joint specimens with different diameters and wall thicknesses and a reduced-scale specimen of reticulated shell were tested on an impact device designed by ourselves. Three deformation modes of joint models are defined. The experimental results indicate that increasing the stiffness by reducing the diameter of the welded hollow ball or increasing its wall thickness can increase
