title: FoRCy: Rocking Shallow Foundation Performance in Slow Cyclic and Monotonic Experiments

description: Numerous centrifuge experiments and 1g experiments by research groups around the world have demonstrated that rocking shallow foundations can be designed to provide re-centering and energy dissipation with little damage to the foundation or superstructure during seismic loading. Each research team has focused on specific response aspects of behavior of rocking foundations and has conducted experiments with different soil profiles, structural properties and ground motions. As a result of this cumulative body of research, the concept of a controlled share of ductility demand between the superstructure and the foundation as a key ingredient for a rationale and integrated approach to the seismic design of foundations and structures has been gaining acceptance within the research and practicing earthquake engineering community. With different specific goals, however, each of the research teams has presented their experimental data in different formats, using different hazard measures, different performance measures, different superstructures, and different foundation shapes and sizes. 
This database (FoRCy) contains data from a large subset of slow cyclic and monotonic experiments that has been processed and normalized so that we can perform “apples-to-apples” comparisons of data from different research groups using the same hazard and performance measures. This allows the data generated by different research teams to be directly compared. FoRCy includes data of shear-wall type structures founded on rocking shallow foundations from seven centrifuges and three 1g shake-table tests, thirteen different soil profiles, nearly 70 slow cyclic tests, over ten monotonic tests and over ten different loading protocols. In total this database describes 456 unique event model case histories.  This database was previously published by DEEDS at datacenterhub.org, but that database hosting service ended and the data was reformatted in 2023 for archiving at NHERI in the Data Depot of DesignSafe-CI.

title: An End-to-End Evaluation of NOAA's Emerging Wildland Fire Detection and Warning Capabilities

description: From June 10-14th, 2024, the National Oceanic and Atmospheric Administration’s (NOAA) newly established Fire Weather Testbed (FWT) conducted its first in-person evaluation of this collaborative approach as well as NOAA's emerging wildland fire detection and warning capabilities, specifically: 1) NESDIS Next Generation Fire System (NGFS) and NWS Hotspot Notification Tool (HSNT); 2) Tactical Integrated Warning Team (IWT) for Fire Operations; 3) Fire Warnings Issued through the Tactical Integrated Warning Team Paradigm. 

The FWT invited NWS fire weather meteorologists and their high-level state land management partners from four U.S. states to understand if and how these emerging technologies, products, and services could be implemented outside of the Southern Great Plains. Throughout the evaluation, pairs of meteorologists and fire managers were grouped by state to form four Tactical IWTs, representing regions with varying firefighting capabilities, fire ecologies, and population distributions. 

These mock Tactical IWTs engaged in seven displaced real-time simulations of recent fire outbreaks. Each simulated IWT received new fire starts detected by the NGFS and sent through the HSNT. If and when the land managers decided to issue a Fire Warning, the meteorologist drew a polygon covering the area of Fire Warning issuance and issued the warning. 

Data was gathered from participants via pre- and post-evaluation surveys and end-of-day roundtable discussions. At the end of the week, the FWT evaluators facilitated two private focus group discussions with participants–one for meteorologists and one for land managers–that were recorded, transcribed, and analyzed by the FWT. Findings from this evaluation are data-driven, while recommendations are both data-driven and informed/contextualized by FWT expertise.

This data provides the semi-structured focus group questionnaire and the surveys used to collect evaluation data.

title: Interview Guide
title: in Policy Innovation in Local Housing Acquisition (Buyout) Programs

description: Hazard-prone housing acquisition or “buyout” programs are among the most effective hazard mitigation measures.  However, these programs are notoriously difficult to administer and communities in the United States (US) routinely struggle to develop and implement them in a timely and well-planned manner. In addition, the sharing of lessons learned (or not learned) among those engaged in housing acquisition programs remains underemphasized. This work explores innovative practices adopted within local housing acquisition programs across diverse US communities, and more specifically, the factors that helped facilitate the implementation of those practices. The results are based off of interviews with 25 local housing acquisition program administrators involved in different housing acquisition programs across US. Results focus on the factors that contribute to housing acquisition policy innovation across all phases of the housing acquisition process, including planning, financing, grant writing, implementation, community relocation, and open-space management. In the context of this study, we define innovation as a practice implemented as part of a housing acquisition program that is new to the community adopting that practice. Lessons highlight the prevalence of policy diffusion, and the importance of community and political motivation, and various community characteristics (such as access to data and technical expertise, staff, partnerships and collaborations, leaders and advocates) in promoting innovation.
description: Included in this collection is an interview guide that can be used for exploring policy innovation in local housing acquisition programs. This research instrument is intended to facilitate the co-generation of data that yields insight into the factors that contribute to policy innovation associated with housing acquisition programs in the United States. The interview guide includes implementation details, a workflow checklist, a pre-interview prompt, a materials checklist, researcher reflections and tips, and the interview questionnaire. The development of the questionnaire was informed by two leading frameworks which seek to explain policy innovation in government settings, Internal Determinants Models and Diffusion Models. Select anonymized transcripts generated using this interview guide will be published in a separate collection following participant revision and approval.

title: in LEAP-ASIA-2019 Experiments (Liquefaction Experiments and Analysis Projects)

description: Building upon the database of LEAP-UCD-2017, twenty centrifuge model tests of liquefaction and lateral spreading are shared and compared in this archive. Some of the experiments were conducted according to the conventional centrifuge scaling laws; others were conducted according to a generalized scaling law. Please see the general report section of the published project for an overview comparison and background of all of the experiments. The comparisons presented in the general report section will serve as an index to help the users find individual experiments of interest.  This data from the model tests is published as ten separate experiments in this archive (one experiment per centrifuge facility). Each "experiment" includes one or more model tests and each model test includes between one and three destructive shaking events.
All of the tests modeled a 4 m thick deposit of Ottawa F-65 sand with a 5-degree surface slope in a rigid box. The tests covered a range of ground motion intensities and a range of relative densities to define the median response and the sensitivity of the response to relative density and shaking intensity. The ten centrifuge facilities involved in this test program included Cambridge University (UK), Ehime University (Japan), IFSTTAR (France), NCU (Taiwan), KAIST (Korea), Kyoto University (Japan), RPI (USA), UC Davis (USA), Tokyo Institute of Technology (Japan) and Zhejiang University (China).

title: HAND-derived Riverine Flood Inundation Maps over Southeast Texas for Hurricane Ike, Hurricane Harvey & Tropical Storm Imelda
title: in HAND-derived Flood Inundation Maps of Southeast Texas

description: Please see the associated GitHub repo: https://github.com/markwang0/HAND_SETX/

This project contains 3-meter by 3-meter resolution GeoTIFFs of riverine flood inundation for Hurricane Ike, Hurricane Harvey and Tropical Storm Imelda. Riverine (fluvial) flood inundation was generated with the Height Above Nearest Drainage (HAND) method and flowrates from the National Water Model (NWM). Maximum flowrates from the NWM during each storm event were converted to flood stage with synthetic rating curves, and the flood stage was converted to spatial inundation. The rasters cover the Southeast Texas Counties of Newton, Jasper, Hardin, Orange and Jefferson. The units are meters of inundation above the surface. The projected coordinate reference system EPSG:5070 is used. Please note that only riverine (fluvial) flooding is shown on each raster. Pluvial flooding and storm surge are neglected.
description: This purpose of this project is to share high-resolution (3m x 3m) flood inundation maps of past storm events to support planners and the impacted community. These maps are generated with approximate GIS-based methods and should not be considered definitive. This project contains GeoTIFF rasters of flood inundation for storm events in Southeast Texas. Please see each simulation description for more specific information.

title: Ash morphology
title: in Characterization and Geotechnical Properties of Wildfire Ashes

description: Particle morphology was observed using a scanning electron microscope (SEM TM 1000).
description: This project summarizes the geotechnical engineering properties of eight samples of wildfire ash sampled from three different wildfire sites in central and southern California. This data can be used in conjunction with data collected from others to provide a database of the physical, chemical, hydrological, and engineering properties of wildfire ashes. Extensive engineering testing of wildfire ashes is not readily available in literature, so this work will supplement the supply currently available. This work would be information and educational for those researching wildfire ashes, fire-exposed slopes, carbonate-rich soils, and manmade soils, including other types of ash. This data can be reused by those who would like reference data for further testing on wildfire ashes and for those who require reference data on soil engineering properties.

title: Contribution to Cold-Formed Steel Seismic Design within CFS-NHERI Project

description: This project uses Cold-Formed Steel (CFS) to address the need for multi-hazards resilient buildings. The research conducted was to correlate observed physical damage from video with key analog measurements at different performance levels. In addition, a 3D AutoCAD model complete with architecturally finishes of 10-story CFS test buildings was created. The work presented in this project will help in the understanding of the structural behavior of CFS in-line wall using recorded videos with analog sensor data in a composed video. The 3D geometrical model will be used to construct the 10-story test building in UCSD. Going forward, this project will benefit the structural engineering community in the understanding of CFS wall-line behavior.

title: Earthquake-Resistant T-shaped Concrete Walls with High-Strength Steel Bars
title: in Earthquake-Resistant T-shaped Concrete Walls with High-Strength Steel Bars

description: For many years, U.S. building codes for structural concrete have not permitted the use of high-strength reinforcing bars with a nominal yield strength greater than 80 ksi (550 MPa) for purposes other than as transverse reinforcement for confinement. Increased understanding and acceptance of high-strength steel bars would allow designers to reduce the amount of reinforcement used in structural members, resulting in less reinforcement congestion, simpler construction, and reduced cost. 
The main objective of this study is to determine the effect of the tensile-to-yield strength ratio of high-strength reinforcing bars on longitudinal reinforcement strain demands and on the overall behavior of slender T-shaped reinforced concrete walls. This investigation also aimed to determine the minimum uniform elongation required of high-strength reinforcement used in earthquake-resistant structures. Study of T-shaped walls is important because the shape of the cross-section results in larger longitudinal reinforcement tensile strain demands than in most other members. The effect of replacing conventional Grade 60 (420) reinforcement with a reduced amount of high-strength Grade 100 (690) reinforcement (with nominal yield strength of 100 ksi, or 690 MPa) is evaluated in this study using data from tests of large-scale reinforced concrete walls subjected to reversed cyclic displacements.
