Assessment of seismic design provisions for multi-tiered ordinary concentrically braced frames
… and impose additional flexural demands on the columns. These flexural demands, in combination with axial demands, can cause column instability and compromise the seismic performance of the frames. The seismic design provisions for multi-tiered ordinary concentrically braced frames (MT-OCBFs) …

Failure and crippling of graphite-epoxy stiffeners loaded in compression
… to failure. Seventeen specimens exhibited local buckling of flanges and webs prior to failure, four exhibited global column buckling prior to failure, two exhibited material short column failure, and one exhibited unstable postbuckling behavior prior to failure. The buckling loads for each …

Parametric buckling analyses of plates
Classical methods for solving plate buckling problems involve using different forms of solution on case by case basis. In place of this approach, this thesis presents a novel single form equation and the parameters required to account for the interaction of geometry, boundary conditions and …

Multiscale structural investigation of bamboo under compressive Loading
… to its strength in compression. We find that column buckling is a critical failure mode that leads to overall collapse of the structure, which can be disastrous. We observe that the gradient fiber distribution pattern along the bamboo thickness direction significantly contributes to its …

Eigenvalue optimization and its applications in buckling and vibration
… of problems is a pre-requisite for vibration and buckling analyses of structures. Design optimization of structures to prevent failure due to instability (bucking) and vibration introduces the problem of determining optimal physical parameters such that load carrying capacity or the fundamental …

Aero-servo-viscoelasticity theory: lifting surfaces, plates, velocity transients, flutter, and instability
… the von Koch rules that previously appeared for column buckling problems. After elimination of the spatial component, an ordinary integral-differential equation in time remains. The dynamic stability of elastic and viscoelastic problems is assessed using the determinant of the governing system of …

Variations in low-grade wood modification and stress lamination
… detailing, construction, and testing of straight columns further establishes structural performance and feasibility. Test results from shearing five full-scale stress-laminated connections show performance beyond that of conventional mechanical fasteners. Twenty-five columns were also tested at …
