Static Behaviors and Applications of Buckling Monitoring Members with Rigid Ends

The buckling of compression members may lead to the progressive collapse spatial structures. Based on sleeved member, monitoring member is introduced control and raise alert by sensing contact between core tube restraining tube. Considering rigid connection among in structures, with ends needs be further analyzed. An experimental test was conducted finite element analyses were performed calibrated models. results indicated that ultimate bearing capacity post-ultimate enhanced due restraint from successfully sensed pressure sensor, revealing it Parametric studies conducted, indicating protrusion, slenderness ratio, gap tube, flexural rigidity ratio are key parameters affecting failure modes some values proposed obtain good capacity. parametric studies, buckling-monitoring summarized as global local buckling. stress distribution deformation mode presented non-contact, point-contact, line-contact, reverse-contact state. applied a reticulated shell substituting members. It can effectively improve shell.
