Structural instability is one of the main failure modes dominating the capacity of structural components. The investigation of nonlinear instability behavior is therefore essential to ensure integrity and ductility of structures subject to seismic loadings. This symposium serves to communicate latest findings in structural instability behavior under earthquakes using cutting-edge computational techniques. The topics include, but not limited to, novel modeling approaches for nonlinear instability, computational evaluation of structural robustness and resilience with explicit consideration of instability, and numerical simulation of interaction between instabilities and other failure modes such as fracture and collapse. Proposing seismic design guidelines or applying active/passive control devices to limit or take advantage of instability behavior based on high-fidelity simulations are also welcome. The symposium aims to exchange the state-of-the-art computational approach of instability behavior among people working with various structural materials and systems in earthquake engineering.
