Rocking-isolated frame structures: Margins of safety against toppling collapse and simplified design approach
2012
Soil Dynamics and Earthquake Engineering
This paper aims to explore the limitations associated with the design of "rocking-isolated" frame structures. According to this emerging seismic design concept, instead of over-designing the isolated footings of a frame (as entrenched in current capacity-design principles), the latter are under-designed with the intention to limit the seismic loads transmitted to the superstructure. An idealized 2-storey frame is utilized as an illustrative example, to investigate the key factors affecting
