Fiber Model Considering the Local Instability Effect and Its Application to the Seismic Analysis of Eccentrically Compressed Steel Piers

To propose a seismic response calculation model for eccentrically compressed steel piers that can consider the local instability effect and horizontal bidirectional earthquake actions, in-plane out-of-plane pseudo-static numerical simulation analysis are performed to study applicability of improved fiber model. The comparison results with refined hybrid-element show accurately simulate hysteretic performance in or directions be used calculate structural requirements under action rarely met earthquakes.
