Rolling and rocking of rigid uplifting structures

JA Bachmann, MF Vassiliou… - … & Structural Dynamics, 2019 - Wiley Online Library
Allowing structures to uplift modifies their seismic response; uplifting works as a mechanical
fuse and limits the forces transmitted to the superstructure. However, engineers are …

A finite element model for seismic response analysis of deformable rocking frames
