The Christchurch Women's Hospital, completed in March 2005, is the only base-isolated building in the South Island of New Zealand. The displacement capacity of the base-isolation system and the super-structure ductility capacity are designed to meet 2000-year return-period demands. Detailed structural evaluations after the 2010 Darfield Earthquake and the 2011 Christchurch Earthquake revealed damage only to sacrificial non-structural components at the seismic gaps. Because the structure was not instrumented at the time of these earthquakes, basic design information, ground motion records from nearby sites, and first-hand accounts of the motion in the structure are used to estimate the responses to the main shock and a large after- shock. Results from this modeling effort are used to corroborate reports of structural response from staff present at the time of the main shock and aftershocks. Subsequent instrumentation of the structure is described and will be used to collect aftershock responses for validation of numerical models

Dynamic Testing of Single- and Double-Story Steel-Sheathed Cold-Formed Steel-Framed Shear Walls
Author: Iman Shamim; Jamin DaBreo; and Colin A. Rogers | Size: 2.8 MB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2013 | pages: 11
This paper describes an experimental investigation of steel-sheathed cold-formed steel-framed shear walls by means of dynamic shake table tests. The objective was to evaluate the seismic performance and to identify whether the shear-wall behavior was consistent with past static tests, to obtain measures of damping and natural period of vibration, to investigate the influence of a second story, and to validate and improve the accuracy of the numerically predicted force-deformation response. The scope of study comprised five single-story and five double-story walls of the platform framing technique. Each wall was subjected to a suite of excitations: impact test to measure the linear-viscous damping ratio, harmonic excitation to estimate the natural period of vibration, and ground motions representative of the seismic hazard in Canada. An overview is presented of the test setup and dynamic loading protocols, as well as the test results and numerical model.

In the analysis of soil–pile interaction under lateral load, the behaviour of soil around a pile is an important parameter
which has a great influence on the results. In this paper the three-dimensional deformation pattern of soil around
laterally loaded piles was studied on small-scale physical models in the laboratory using the particle image velocimetry
method. In each step of loading two digital cameras were used to capture the deformed piles and soil, one above and
the other on the side. One of the cameras was placed vertically in front of the test box and the other horizontally on top
of it. Image processing was undertaken to evaluate the three-dimensional behaviour of deformed soil. Particle image
velocimetry analysis was undertaken to obtain the displacement. The deformation pattern and shear strains of soil
around laterally loaded single pile and pile groups were studied. The effects of pile length, stiffness and diameter on the
soil deformation pattern were investigated. The group effect and interaction between piles in pile groups were also
studied. Experimental results showed that a conical passive zone is established in front of laterally loaded piles.

This article uses a model test and PFC2D discrete element simulation
for systematic research on the mechanism and behavior of soil arching around passive
piles in sand. In the model test, soil arching effects with different pile spacing was
studied. In the discrete element simulation, the influence of pile spacing on soil
arching was revealed at the meso-level. The model test indicates that pile spacing
influences soil arching effects significantly. Numerical analysis also shows that pile
spacing is the most significant factor on soil arching surrounding passive laterally
loaded piles. From this study, the meso-mechanism and behavior of soil arching are
discovered further.
