The rocking of structures during earthquakes is both essential to the assessment of existing structures and promising for the development of novel seismic design methods. Regarding assessment, the seismic collapse of masonry structures will first be considered, and will be used to introduce the fundamental characteristics of rocking motion. In this context, a new framework will be presented which aims to significantly improve code-based procedures for assessment of out-of-plane collapse.
Regarding seismic design, more stringent seismic performance objectives are inspiring new design methods which aim to reduce or locate damage, even for large earthquakes. One such method, which uses rocking to isolate the structure from the ground motion, will be considered. In particular, the relative importance of flexibility, the effect of rocking on elastic modal response, and the effect of near-source ground motion will be discussed. Shake table test results will also be presented. In general, the results provide a basis to improve current design methods.
Bio : Dr Matthew DeJong is a Lecturer in Structural Engineering at the University of Cambridge, where he leads a research group focused primarily on earthquake engineering and masonry structures. Prior to his current appointment, he earned his BS at UC Davis, his MS and PhD at the Massachusetts Institute of Technology, and he was a Fulbright Scholar at TU Delft. He has also worked as a structural engineering design consultant in California.
