title: StEER 2020 Hurricane Delta Field Assessment Structural Team Dataset: FAST 1 and FAST 2
title: in StEER - Hurricane Delta

description: As the strongest hurricane on record named with a Greek letter, Hurricane Delta made landfall in Mexico near Puerto Morelos, Quintana Roo as a Category 2 hurricane on 7 October 2020, with a second landfall in the United States as a Category 2 hurricane on 9 October 2020 in Creole, LA. This U.S. landfall was roughly 10 miles east of the location where Hurricane Laura made landfall on 27 August 2020 as a Category 4 hurricane. This project encompasses a curated dataset an Event Briefing, an abbreviated StEER response mechanism that briefly summarizes the event and any key lessons that can be learned based on publicly available data and the impressions of Field Assessment Structural Teams (FAST) who deployed regionally to assess the impacts. Specifically, StEER activated FAST-1 and FAST-2 between 12-15 October 2020 to deploy rapid imaging techniques using the same teams and hardware that surveyed Hurricane Laura. The first team operated out of Auburn University 12-13 October and the second team out of Louisiana State University 14-15 October; FAST-2 liaised with other local researchers. Their combined data collection efforts emphasized a longitudinal data capture of areas previously documented for Hurricane Laura, as well as new clusters exposed to some of the Delta’s highest wind speeds to the east of landfall.
description: The response leveraged small, self-contained, regional FASTs deploying in phases to collect rapid assessment data using vehicle-mounted street-level panoramic imaging platforms, with select use of UAS. Routes were selected to ensure longitudinal data capture of areas previously documented for Hurricane Laura, as well as new clusters exposed to some of the Delta’s highest wind speeds to the east of landfall.

title: Generation of Large-Scale Gust Structures in a Large Boundary Layer Wind Tunnel: 3D Flow Measurement Experiments
title: in Physical Simulation of Terrain-Induced and Large-Scale Turbulence Effects on the Effectiveness of Wind Mitigation Strategies for Low-Rise Buildings

description: Wind-induced damage to roof components of buildings is mainly initiated by extreme suction pressures caused by vortices that develop when the oncoming wind flow impinges on the structure, resulting in flow detachment near roof corners and edges. Previous studies have demonstrated the effectiveness of several roof load mitigation strategies for alleviating uplift roof pressures under a limited set of idealized turbulent flow conditions. This project leveraged a flow-control instrument, Flow Field Modulator (FFM), at the University of Florida Natural Hazards Engineering Research Infrastructure (NHERI) Experimental Facility to actively generate a wider range of turbulent flow conditions in a large boundary layer wind tunnel (BLWT). The FFM is a 2D multi-fan array comprising 319 modular hexagonal aluminum cells with shrouded three-blade co-rotating propellers. The system enabled the active generation of large-scale turbulent structures by recreating user-specified velocity time signals to inject slowly varying fluctuations into wind tunnel flows. The project aimed to overcome ongoing limitations in traditional wind tunnel modeling approaches by enabling active and precise control of large wind gust structures to evaluate their impact on civil infrastructure.
description: This dataset includes flow velocity time series collected in a large boundary layer wind tunnel (BLWT) to investigate the intensity of large-scale turbulent gust structures generated by a novel flow-control instrument. The work leveraged a multi-stage flow conditioning system consisting of an active multi-fan gust generator, termed flow field modulator (FFM), that operated in conjunction with an automated roughness element grid (called Terraformer). The primary goal of the study is to assess the effectiveness of the coupled flow conditioning system (FFM and Terraformer) for increasing and tuning large-scale (particularly near-surface) turbulent structures that will enable characterization of their impact on building loads at relatively large BLWT scales (> 1:50). The dataset can be used and compared against previously published velocity measurements collected using traditional BLWT flow conditioning approaches (i.e., no active control of large-scale turbulence).

title: Research Experiences for Undergraduates (REU), NHERI 2022: Comparison of Material Model Calibration Methods Using Response Predictions from Component Model

description: This project employed three different methods of material model calibration and evaluated these methods based on the accuracy of the predictions from a structural component model that incorporated these calibrated material models. The data from this project can be used to reduce the uncertainty of structural models by demonstrating which feature should be matched during material calibratin to get the most accurate predictions of quantities of interest at the system level. This research project was unique because it used the results from dynamic tests conducted on a full-scale structure to evaluate the predictions of a structural component model and the performace of material model calibration methods. The intended audience of this work is engineers and researchers interested in modeling structures under dynamic loadings, such as earthquakes, who would like to investigate how the method of material/component model calibration used contributes to model uncertainty at the system level.

title: Shake table test of a 2-storey low-damage concrete wall building
title: in ILEE-QuakeCoRE Shake table test of a 2-storey low-damage concrete wall building

description: A system level shake-table test of a 2-storey low-damage concrete wall building was conducted on the multi-functional shake-table array at Tongji University. The test building used post-tensioned (PT) precast concrete walls and precast concrete frames with slotted beam connections. The test building was configured in seven different designs with a range of design drift targets, wall PT configuration, and alternative energy dissipating devices installed at the wall base and slotted beam joints. The building was subjected to 39 separate ground motion tests, consisting of the different design configurations and combinations of ground motions including different intensity records, far field and near fault records, and short and long duration records. The test building were monitored by 14 video cameras, 360 sensors for both global and local response, and inspections between each phase of tests. The project documentation was recorded comprehensively throughout the whole process of the test, including building design, construction, setup, instrumentation, testing and demolition. The recorded documentation and data has provided a significant high-quality dataset to verify design procedures, detailing practice and numerical models.

title: Hybrid Simulation and Quasistatic Test - Prototype B
title: in Hybrid and Cyclic Testing of Steel Moment Frames with Deep Column

description: Steel moment frames composed of wide-flange steel members are commonly used in seismic regions, with deep and slender column sections often selected to economically satisfy drift limit requirements. The section slenderness makes the columns more susceptible to local and global buckling and subsequent axial shortening when subjected to combined high axial forces and lateral deformations. Numerous tests have been conducted on individual column members under a wide range of axial loads and loading patterns. Experimental data of subassembly or complete frame configurations providing insight into system level interaction of the column with the frame are limited. This study presents experimental results from a full-scale testing program conducted on four cruciform beam-to-column subassemblage subjected to loading patterns based on cyclic quasi-static and slow hybrid simulation. Quasi-static tests followed standard AISC loading protocol with constant column axial load ranging from 20% to 40% of the yield capacity. Advanced hybrid simulations were also conducted to subject the specimens to realistic earthquake loading patterns to levels consistent with design basis earthquake (DBE) and maximum considered earthquake (MCE) ground motions. A full nonlinear model of a complete 6-story frame was developed for the numerical substructure in the hybrid simulation. The observed local and global responses of two quasi-static and two hybrid tests are presented, providing valuable data towards improving the understanding of progress of damage for these systems through advanced testing techniques.

title: SUBSA Brazing of Aluminum Alloys IN Space
title: BRAINS

description: The primary scientific goal of the proposed  terrestrial and planned microgravity molten metal  capillary flow experiments is to better understand the physics of the flow of molten metals over the topographically modified surfaces (e.g., filling in the holes, flow over sharp edges and/or flow over surfaces having variable curvatures). By performing capillary flow tests both on Earth and in a microgravity environment, the effects of microgravity on the kinetics of the larger masses of melt flow, and ultimate equilibrium shape of the meniscus will be closely examined. The objective of the microgravity experiments is to provide benchmark data against which theoretical models and computer simulations can be tested. The BRAINS project’s primary pragmatic/engineering obective is that a capillary flow of braze under microgravity conditions would enable a repair or bonding of larger and/or more irregular mating surfaces defects, compared to the terrestrial conditions. This would be important for future development of advanced brazing techniques with applications to both damage repair and construction in space.

title: Rectangular Column Database

description: This database is provided by extending the one presented by Ghannoum et al. (2015) entitled “NEES: ACI 369 Rectangular Column Database”, which can be found on https://datacenterhub.org/resources/255. In this extended version, two new terms including the yield drift ratio and the displacement ductility demand are added to the original database through available technical reports, articles, and dissertations in the literature, since the latter parameter plays a key role in estimating the shear strength of reinforced concrete columns. This database provides wide range of information about 325 tested rectangular columns including geometry details of columns’ sections, mechanical properties of concrete and reinforcing steel, configuration of transverse and longitudinal reinforcements, loading patterns, and the measured results that can be employed by researchers to conduct numerical studies in the context of structural/earthquake engineering.

title: Wireless Sensor Network System Deployment During Hurricane Ian, Satellite Beach, FL, September 2022
title: in Hurricane IAN Data from Wireless Pressure Sensor Network and LiDAR

description: The Florida Tech Wireless Sensor Network System (FIT WSNS) measured and recorded pressure, temperature and wind data during the passage of Hurricane Ian from 2022/9/27 to 2022/9/30. The FIT WSNS deployment consisted of 17 pressure sensors with sampling rate (SR) = 10Hz, 1 reference pressure with SR = 10Hz and 2 R.M. Young anemometers with SR = 1Hz.  They were deployed on a residential house in Satellite Beach, Florida (GPS LOC: 28°10'33.5"N 80°35'41.8"W). The goal of this deployment was to measure surface pressure loads on the building components and compare to reference and ASCE 7 specification values.

The FIT WSNS deployment consisted of 17 pressure and temperature sensors with sampling rate (SR) = 10Hz, 1 reference pressure with SR = 10Hz and 2 R.M. Young anemometers with SR = 1Hz. They were deployed on a residential house roof in Satellite Beach, Florida (GPS LOC: 28°10'33.5"N 80°35'41.8"W).  The Florida Tech LiDAR, a conically scanning ZephIR Z300 LIDAR was placed in a secured yard approximately 50 m  (~ 150 ft) across the street and configured to measure at 11 different range gates (11 m - 300 m AGL). Additional meteorological data (ambient air temperature, relative humidity, and barometric pressure) were collected from an independent Airmar meteorological station on top of the LiDAR at 1 m AGL.

The different anemometry used in the WSNS and LiDAR deployments during Ian allowed the investigators to study wind changes across the residence. 

The goal of the Ian Deployment was to 1) Measure actual near-surface wind profiles for different wind speeds and directions; 2) Analyze wind pressures on the residential house roof and wind data from different anemometry, with Jupyter notebooks; 3) Provide field data to validate and improve current wind loads recommendations and models for pressure distributions on building components, wind profiles and terrain roughness characterization.

title: Research Experiences for Undergraduates (REU), NHERI 2023: Direct Push Crosshole Testing: Assessment of Post-liquefaction Soil Saturation and Stiffness in Kawaihae Harbor, Hawaii

description: The project's main focus is on studying soil conditions, particularly saturation and stiffness, to evaluate the possibility of soil liquefaction recurring after the 2006 Kiholo Bay earthquake, using the direct push crosshole test (DCPH). The data produced by the project holds potential for various uses, including comparative analysis with other datasets related to soil liquefaction in Kawaihae Harbor, Hawaii and foundational reference for any future changes in liquefaction mitigation standards or guidelines. The project's uniqueness lies in its innovative combination of the DCPH technique and the NHERI Largescale Mobile Shakers’ T-Rex for data collection, offering a fresh approach to understanding soil behavior. Notably, this approach is applied to gather shear wave data on calcareous soils in Kawaihae. While the project's primary audience is those interested in the geotechnical field and earthquake studies, its insights also cater to a broader audience interested in soil behavior and seismic events.

title: Fault Displacement Feature Interpretation
title: in Ridgecrest, CA earthquake sequence, July 4 and 5, 2019

description: This dataset consists of field photographs taken as part of the original Geotechnical Extreme Events Reconnaissance (GEER) Association and Southern California Earthquake Center (SCEC) reconnaissance activities conducted following the M6.4 July 4, 2019 Ridgecrest event. The photographs documenting surface displacements are a subset of those from GEER and SCEC missions originally published with DOIs https://doi.org/10.17603/ds2-vpmv-5b34 and https://doi.org/10.17603/ds2-c5z3-wy42, respectively, and document the surface fault trace areas for the M6.4 and M7.1 events. The photographs included in this newly aggregated mission were analyzed as part of the development of a manuscript that includes the identification of surface displacement features. While the photographs are not new (they were included in previous missions), the folder names and file organization are consistent with those in the electronic supplement of the new publication, for convenience.

Am. XX, 1–17, doi: 10.1785/0120200222
description: The Ridgecrest Earthquake sequence included a M6.4 event on July 4 2019 followed by a M7.1 July 5 2019. These events occurred in the Eastern California Shear Zone, near Indian Wells Valley, south of China Lake and west of Searles Valley. The Geotechnical Extreme Events Reconnaissance (GEER) Association has partnered with several organizations to collect perishable data and document the important impacts of these events, including the United States Geological Survey, the California Geological Survey, the US Navy, the Southern California Earthquake Center, the National Aeronautics and Space Agency (NASA) Jet Propulsion Laboratory (JPL), and local utilities. Critical geotechnical features of this event are extensive surface ruptures, roads, water pipes, and gas pipes crossing the faults, liquefaction and lateral spreading, and liquefaction effects on structures. These effects are documented using field (ground) mapping, and Structure from Motion (SfM) using images collected by UAV's to develop high-resolution digital elevation models.
