Simplified numerical model for global stability of corrugated silos with vertical stiffeners

Linear buckling analyses of silo: buckling load factor λ versus column number n: a) entire silo 3D model, b) and c) by EC3, d) simplified segment silo model with hinges at ends, e) simplified model without hinges at ends, f) 1D column model based (with hinges at ends), g) 1D column model based (without hinges at ends).105
