SEISMIC RESPONSE OF PILES - SOME RECENT DESIGN STUDIES

Three recent design studies are described, which examine the response of piles in soft soils to the soil deformations caused by severe earth quakes, The structures involved were a massive warehouse, a major new bridge and a large coal unloading jetty Different analytical methods o f varying complexity were used for the three studies, Although none of the analytical methods was completely rigorous, they were considered to capture the fundamental aspects of the problems investigated, and y ielded results which were useful for design.
