Spatial stability of braced thin-walled members of steel structures

Static properties and stability of cylindrical ILTDBS reticulated mega-structure with double-layer grid substructures

“…As we know, after the plane-plate grid substructures have been installed in the large grids of the cylindrical ILTDBS reticulated mega-structure, the double-layer plane-plate grid substructures have no stability problem [8][9][10][11][12]. But the main structure still has a stability problem because it is a super reticulated cylindrical shell structure.…”

Structural optimization and dynamic analysis for double-layer spherical reticulated shell structures

“…A subspace iterative method is used to analyze the modes of double-layer reticulated shells shown in Fig. 1 which have 4 different spans (L = 50 m, 100 m, 150 m, 200 m), 13 different height-tospan ratios ( f /L = 1/2, 1/2.5, 1/3, 1/3.5, 1/4, 1/4.5, 1/5, 1/5.5, 1/6, 1/6.5, 1/7, 1/7.5, 1/8) and 6 different grid division frequencies (5,6,7,8,9,10) as stated in Ref. [20].…”

“…The design for these structures is emphasized more on architectural aesthetics than on structural reliability and economical efficiency [1][2][3][4]. Research work for large span special reticulated shell structures was mainly focused on stability analysis [5][6][7], buckling and path tracking [8][9][10] and elastoplastic large deformation simulation. Only a few researchers investigated structural optimization, and they concentrated on minimum weight optimization [11,12].…”

The influence of the torsional restraint of crane column brackets on their critical load capacity

“…The majority of available literature only refers to very well examined flexural-buckling [3][4]. More complex examples of flexural torsional buckling of laterally restrained I-sections are presented, among others, in [5][6], and with reference to elements with stepped change of their sectional stiffness, in [7][8].…”
