Buckling of compression-loaded multispan stiffened panel upon failure of joints between panel and supports

摘要

In research of stability of stiffened panels it is usually supposed that joints between panel and with supports do not fail at buckling. However, these joints can turn out to be insufficiently strong, and buckling of the panel can be accompanied with their destruction in limited areas. Thus the separated fragments become buckled (with finite amplitude of out-of-plane deflection) And the work for destructing the joints is dispersed. Examples include buckling of a compression-loaded multispan stiffened panel upon destruc- Tion of attachment to transverse and/or longitudinal supports.
