Prediction of the buckling load. Buckling occurs in the axially compressed region in the neighborhood of the midlength of the downward bent beam |
|
Pre-buckling residual stress through the wall thickness from rolling a flat sheet into a tube |
|
Distributioin of residual stresses across the thin-walled profile (cross-section). |
|
Three general buckling modes of an arch |
|
A frame made of beam-columns with thin-walled hollow rectangular cross section |
|
Deformation of the thin-walled hollow frame under the loading shown in the previous image |
|
A thin-walled curved beam |
|
Thin-walled curved beam with "I" cross section |
|
Each segment of the cross section of the I-beam is made of laminated composite material |
