Abstract

Title: U.S. Instrumentation and Data Processing of a Large-Scale Experiment on Soil-Structure Interaction of Underground Structures on the E-Defense Shake Table in Miki, Japan (NEES-2014-1168)

Year Of Curation: 2014

Description: The structural and geotechnical performance and post-earthquake functionality of underground systems in megacities are of great concern when located in an active seismic region. Typically, underground systems consist of combinations of tunnels, vertical shafts, pipeline systems, utility facilities, or parking/shopping centers coupled via flexible or rigid connections. The large-scale, soil-structure interaction experiment of underground structures under dynamic loading conducted on the E-Defense shake table in Miki, Japan, in February 2012 provides the unique opportunity to study local and global behavior of tunnel-shaft systems installed in a laminar soil container under a series of two-dimensional ground motions. The objective of this award is to provide supplemental instrumentation to be installed in and around the test specimen in the laminar soil container to measure engineering response quantities such as the vertical distribution of dynamic horizontal pressures, lateral cyclic displacements, axial and transverse strain distributions, and the interaction (forces and displacements) of adjacent systems.
