Abstract
Test series 2 investigates the seismic performance of a scale model of the
prototype soil-foundation-structural system at liquefied and softened ground
sites. This test series is anticipated to develop insight into the foundation
movement of structures at sites undergoing liquefaction. The timing, sequence,
and location of soil strength loss in the vicinity of the structures were documented
closely. The documentation of the effects of Soil-Foundation-Structure
Interaction (SFSI) and the seismic performance of three different types of
structures at liquefied and softened ground sites (with Nevada sand and
Adapazari silt as the liquefiable loose saturated sandy material) is valuable,
because analytical methods for evaluating these effects are extremely limited at
this time. Engineers generally apply methods developed for estimating the freefield seismic settlement of clean sand deposits to evaluate how much the ground
and possibly the building foundation may displace.
