Spatial Grid

Among the long-span spatial structures, the grid shell has many advantages compared to the other spatial structures.Because of the combination of the reasonableness of mechanics and the economy production,and characteristics of the light-duty and the mature design methods,this structure has more wider application than the others.At present,the static stability problem of spatial grid shell structure has been well solved,but the research about dynamic properties and seismic performance is imperfect,especially about single-layered cylindrical grid shell.So this paper does some research about the seismic performance on the base of numerical analysis.

Golden Section Method

Finite element solutions are presented for the optimal design of hemispherically and flat-capped symmetrically laminated pressure vessels subjected to external pressure. The effect of vessel length, radius, and wall thickness, as well as bending-twisting coupling and hybridization on the optimal ply angle and buckling pressure are numerically studied. Comparisons of the optimal fiber angles and maximum buckling pressures for various vessel geometries are made with those for a hybrid pressure vessel. The well-known golden section method is used to compute the optimum angle in each case.

Circular Cylindrical Shells

Pappas and Allentuch in the title paper computerized the investigation of a minimum-weight, ring-stiffened, elastic circular cylindrical shell under external pressure and obtained results similar to those found by Gerard in closed form in 1961.
