title: Annual Fossil-Fuel CO2 Emissions: Isomass of Emissions Gridded by One Degree Latitude by One Degree Longitude (1751 - 2009) (V. 2012)

description: The annual, isotopic (δ 13C) fossil-fuel CO2 emissions estimates from 1751-2009 provided in this database are derived from time series of global, regional, and national fossil-fuel CO2 emissions (Boden et al. 2012) and references therein. The data accessible here take these tabular, national, mass-emissions data, multiply them by stable carbon isotopic signatures (δ 13C) as described in Andres et al. (2000), and distribute them spatially on a one degree latitude by one degree longitude grid. The within-country spatial distribution is achieved through a fixed population distribution as reported in Andres et al. (1996). Note that the mass-emissions data used here are based on fossil-fuel consumption estimates as these are more representative of within country emissions than fossil-fuel production estimates (see http://cdiac.ess-dive.lbl.gov/faq.html#Q10 for a description why emission totals based upon consumption differ from those based upon production).

title: Aspect (3" resolution) derived from 1" SRTM DEM-S

description: Aspect measures the direction in which a land surface slope faces. The direction is expressed in degrees from north.

The aspect product was derived from the Smoothed Digital Elevation Model (DEM-S; ANZCW0703014016), which was derived from the 1 second resolution SRTM data acquired by NASA in February 2000. The calculation of aspect from DEM-S accounted for the varying spacing between grid points in the geographic projection. 

This 3” resolution version of the aspect product has been masked by the 3” water and ocean mask datasets.

title: Dynamic System Identification on DBF - Rigid Links OFF - Ground Links ON - Loading Beams OFF

description: System Identification Tests conducted in Lehigh University aim identifying DBF's dynamic characteristics, in terms of frequencies and mode shapes. The results will be used to model the frame for control purposes during RTHT.
The tested structure has no loading beams and rigid links on brace points attached.
Each in-plane and out-of-plane repetitions contain 10 to 20 hammer hits. In-plane tests took 400 seconds, out-of-plane and ambient vibration tests took 300 seconds.
In this experiment ICP/PCB sensors are used. The structure is hit with an impact hammer to get the free vibration of the structure. The signal generated by hammer and sensors are collected by a top-of-edge DAQ system with a built-in ICP signal conditioner, VibPilot. Both sensors and DAQ system used for these experiments were non-NEES and are documented in the Documentation. The binary file of the collected data is converted with VibPilot software, SO Analyzer into MATLAB files.

title: Evaluation of Structural Control Strategies for Improving Seismic Performance of Buildings with MR Dampers Using Real-Time Large-Scale Hybrid Simulation

description: During the past decade numerous researchers have investigated the dynamic behavior of structures with magnetorheological (MR) dampers using various semiactive control laws. A majority of the conclusions focused on the superiority of semiactive controllers over passive control. Large-scale MR dampers have not been studied extensively in conjunction with semi-active control laws since only a few experiments have been conducted with large-scale dampers. The assessment of semiactive controllers however needs to be verified more rigorously by using large-scale MR dampers. In this project, real-time hybrid simulations using large-scale MR dampers are conducted to evaluate the effectiveness of various structural control strategies in enabling the seismic performance objectives of a building structure to be achieved. A prototype structure of a 3-story building is designed in accordance with the ICC code to satisfy the strength requirement, and an MR damper is installed to control the drift of the structure. Three different control strategies are considered: (1)passive control; (2) linear quadratic regulator (semi-active control); and (3) sliding mode control (semi-active control). Six ground motions scaled to the same design basis earthquake are used for the real-time hybrid simulations and statistical responses of the structure are obtained to compare the performance of each controller.

title: Near-Surface Wind Speed

description: Daily near-surface wind speeds (u) grids have been developed over all of Australia at a 0.01° spatial resolution by interpolating terrestrial anemometers measurements from an expanded network for 1975–2006. For these new grids, the Australian-averaged u trend for 1975–2006 was -0.009 m s-1 a-1 (agreeing with earlier site-based studies) with stilling over 88% of the land-surface. This new dataset can be used in numerous environmental applications, including benchmarking general circulation models to improve the representation of key parameters that govern u estimation. The methodology implemented here can be applied globally.

title: Centrifuge test SSK01 on prefabricated vertical drains for liquefaction remediation

description: This is the first test in a series of three dynamic centrifuge tests designed to evaluate the effectiveness of prefabricated vertical drains in mitigating liquefaction. Centrifuge testing was performed using the 9-m radius centrifuge at the NEES@UCDavis Center for Geotechnical Modeling. The centrifuge model consisted of sloping ground with liquefiable sand overlain by a low-permeability crust. Water was used as the pore fluid. A centrifugal acceleration of 15g was applied.

The centrifuge model featured untreated and drain-treated mildly sloping (3 degree) soil profiles separated by a central channel. Each slope was
comprised of a 4 to 5 m thick (prototype scale) layer of liquefiable sand overlain by a 1 m thick (prototype scale) clay cap. Accelerometers and pore pressure transducers and linear potentiometers were placed within the model to measure its response. 

The model was subjected to 12 sinusoidal accelearation-time history input motions, each with 20 cycles of motion at a frequency of 2 Hz (prototype scale), and shaking was performed parallel to the slope. The amplitudes of the first three shaking events were too small to be captured by the sensors. The remaining shaking events ranged in PGA from 0.01 g to 0.3 g.

title: Centrifuge test RLH01 on prefabricated vertical drains for liquefaction remediation

description: This is the third test in a series of three dynamic centrifuge tests designed to evaluate the effectiveness of prefabricated vertical drains in mitigating liquefaction. Centrifuge testing was performed using the 9-m radius centrifuge at the NEES@UCDavis Center for Geotechnical Modeling. The centrifuge model consisted of sloping ground with liquefiable sand overlain by a low-permeability crust. Water was used as the pore fluid. A centrifugal acceleration of 15g was applied.

There were three treatment areas within the model - one untreated, one untreated but containing non-draining tubes, and one drain-treated. Each treatment area consisted of three distinct soil layers: (1) a 0.75 m (prototype scale) thick layer of dense Nevada sand (DR ~ 85%) overlain by (2) a 5 m (prototype scale) thick layer of loose, liquefiable Nevada sand (DR ~ 40%), which was in turn overlain by (3) a 1.5 m (prototype scale) thick layer of Yolo Loam clay. Accelerometers and pore pressure transducers and linear potentiometers were placed within the model to measure its response. 

Two earthquake acceleration-time histories were used as the principal input motions: PAC175, a short duration motion from the 1994 Northridge earthquake with only a few significant cycles (D5-75 = 0.62 s, number of equivalent uniform cycles at 65% of the peak (Neq) = 2 to 4), and PSL180, a longer duration motion from the 1971 San Fernando earthquake with more cycles (D5-75 = 5.68 s, Neq = 11 to 15). Shaking took place orthogonal to the slope, and a total of 9 shaking events were applied to the model. Scaled PAC175 and PSL180 input motions, ranging in PGA from 0.11 to 0.95 g, were used for the first 8 shaking events, and a sine wave with 20 cycles of motion at a frequency of 2 Hz and a PGA of 0.6 g was used for the final shaking event.
