title: Natural Hazards Research Summit 2024: Time-Integrated Coastal Flood Risk Assessment to Enhance Civil Infrastructure Resilience

description: As climate change exacerbates coastal flooding threats, critical infrastructure like transportation and energy systems faces increasing disruptions. Rapid intensification of hurricanes, flash floods, and high tide flooding occur more frequently, leaving coastal communities, especially underserved populations, little time to prepare for evacuation. To address this, we're developing a framework to assess how extreme flooding events impact infrastructure over time and under varying climate conditions. Our focus is on understanding how the timing of flooding affects the civil infrastructure and socioeconomic impact on coastal communities. This poster presents early findings using a storm surge machine learning model and a digital elevation model-based compound flood model to rapidly assess flood events. Our research investigates how the timing of these events significantly alters their socioeconomic effects.

title: Improving Storm Surge Forecasts with Transformers

description: This project couples transformers with ADCIRC to render enhanced predictions of storm surge in the United States.  Here, we provide a pre-processing file necessary to create time-contiguous "chunks" for transformer training and evaluation.  This comes from an ADCIRC Global-STOFS hindcast for 2016-2019.  We also provide output from our trained transformers so that users can evaluate performance for themselves.  All "observed" total water levels sourced from NOAA.  All levels with respect to mean sea level vertical datum.

title: Calibrated ATENA-GiD Models
title: in Finite element models of masonry lap-splice tests with Grade 60 and Grade 80 rebars

description: This DesignSafe publication reports three-dimensional finite element model files used for simulating concrete block and clay brick masonry lap-splice tests with Grade 60 and Grade 80 deformed rebars associated with ASCE Structural Engineering Journal Paper entitled “Evaluating Lap-Splice Length Requirements for Grade 80 Deformed Bars in Structural Masonry”. The finite element models were developed using ATENA-GiD, which is required for users to be able to access the files included herein. The developed models have been calibrated with laboratory tests for capturing the lap-splice strength of Grade 60 and Grade 80 bars in concrete masonry and clay brick walls. The finite element models incorporate (a) calibrated constitutive stress-strain curves for concrete and clay brick grouted prisms; (b) calibrated interface bond stress-slip constitutive laws for simulating the interaction between masonry and reinforcing bars; and (c) stress-strain curves for Grade 60 and Grade 80 ASTM 615 and 706 rebars. The reported models in this DesignSafe publication, in part or as a whole, can be utilized for future simulations involving bond slip of rebars in concrete block or clay brick masonry.

description: NHERI@UTexas Levee Imaging Workshop; in St. Louis, Missouri (November 11th 2016)
The workshop started at 8 am on November 11th 2016 at the Marriott St. Louis Airport, at 10700 Pear Tree Lane St. Louis, MO 63134 with presentations from Professors Kenneth H. Stokoe, II, Loukas Kallivokas, and Brady R. Cox from the University of Texas at Austin, Mr. Ryan Goetz from the U.S. Army Corps of Engineers, and Professors Clint Wood and Michelle Bernhardt from the University of Arkansas.  A field demonstration of the seismic testing equipped for 3D levee imaging was held in the afternoon at the Mel-Price Wood River Levee (38 52' 33" N, 90 9' 25" W) near Alton, IL. Much of the Mel-Price Wood River levee is a sand core/clay cap levee, which sits on top of a relatively thin clay blanket underlain by a sand aquifer.  The NHERI@UTexas Levee Imaging Workshop highlighted a potential use of NHERI@UTexas equipment for true 3D non-intrusive imaging of geotechnical systems via full waveform inversion.  During the workshop, we used the urban, mobile, hydraulic shaker Thumper to generate small-strain, dynamic vertical and horizontal loadings on the ground surface at 144 locations on the crest and toe(s) of the levee.  Data collected in this workshop are presented in this project.

title: Phase 1: Slip Behavior in Drywall Partition Walls
title: in Bidirectional Testing of Drywall Partition Walls with Novel Details, Integrated into a Rocking Wall Subassembly

description: The slip behavior of two straight drywall partition walls (without return walls) – one with conventional slip-track detailing and the other with telescoping detailing – was examined. These drywall partition walls were tested under a bidirectional loading protocol, which allowed for systematic evaluation of the effect of out of plane drift on the in-plane resistance of the drywall partition walls.
description: Two different configurations of  drywall partition walls were built within a post-tensioned CLT rocking wall subassembly. The overarching objective is to investigate the seismic performance of drywall partition walls when integrated with a rocking wall system, and to assess the influence of out-of-plane loading on the in-plane resistance of the walls. Both configurations also incorporated novel details aimed to reduce damage at low level seismic drifts. In the first configuration, a double or telescoping top track detail aimed to reduce damage at the wall ends was compared to a conventional slip track detail. In the second configuration, two different gap details (a corner gap and a distributed gap) aimed to delay the onset of damage due to collisions at return walls were compared.

title: Tsunami Debris Motion and Loads in a Scaled Port Setting: Comparative Analysis Data for Smoothed Particle Hydrodynamics
title: in Tsunami Debris Motion and Loads in a Scaled Port Setting: Comparative Analysis Data for Three Numerical Methods

description: Data repository for "Tsunami debris motion and loads in a scaled port setting: Comparative analysis of three state-of-the-art numerical methods against experiments" by Bonus et al. 2025: 
https://doi.org/10.1016/j.coastaleng.2024.104672

Repository includes scaled, 3D tsunami debris simulation results in three numerical methods: the Material Point Method (MPM, ClaymoreUW), Smoothed Particle Hydrodynamics (SPH, DualSPHysics), and Eulerian grid-based computational fluid dynamics (CFD, Simcenter STAR-CCM+). This data repository contains results on the long wave generation from a vacuum-controlled tsunami wave maker, longitudinal displacement of debris forward and back, lateral spreading angle of debris, interactions of stacked debris, and impact forces measured with debris accelerometers and/or obstacle load-cells for the digital flume models of each respective numerical method.

The comparative analysis is done for a benchmark set at 1:40 Froude scale to model experiments of shipping containers mobilized into and amidst a port setting with simplified and generic structures, closely related to the seminal Tohoku 2011 tsunami case histories which majorly affected seaports. A wave flume at Waseda University in Tokyo, Japan, hosted the experiments as reported by Goseberg et al. 2016 (https://doi.org/10.1016/j.coastaleng.2016.08.012). Across dozens of trials, an elongated vacuum-chamber wave surges and spills over a generic harbor apron, mobilizing 3–6 hollow debris-modeling sea containers-, in 1–2 vertical layers against friction. One to two rows of 5 square obstacles are placed upstream or downstream of the debris, with widths and gaps of 0.66x and 2.2x of debris length, respectively.

The data repository is intended for inclusion in further comparative analysis efforts that study the efficacy of numerical methods and software for tsunami debris modeling.
description: Smoothed Particle Hydrodynamics (SPH) was applied in a comparative analysis study to replicate stochastic wave flume experiments on tsunami debris motion and loads in a scaled port setting. DualSPHysics was the software used. Configuration files for the digital flume's specification per experimental case are contained along with their corresponding output files (e.g., wave-gauges, load-cells, debris-trackers).

title: A grey literature review on media representation of animals in the 2023 wildfires in Nova Scotia, Canada
title: in A grey literature review on media representation of animals in the 2023 wildfires in Nova Scotia, Canada

description: This study explores the media representation of animal-related issues during emergency response to wildfires in Nova Scotia, Canada. This paper aims to highlight the major issues present in the media during different stages of the emergency, looking specifically into three themes: preparedness, response, and recovery. The study adopts a content analysis approach to analyze data from multiple sources, including social media outlets (i.e., Twitter), government websites, and local news organizations’ publications between May and June 2023. The research highlights a range of practical examples when human-animal interactions can improve mutual resilience. To date, there are no unified standards for building media strategies related to supporting affected animals, specifically regarding the media representation of animal-related issues during disasters. The study offers a unique insight into the human-animal interactions during wildfires, a niche and specialised sub-field in disaster research.

title: Natural Hazards Research Summit 2024: Innovations in Cold-formed Steel Design and Construction: Towards Tall, Fast, Dry, Multi-hazard Resilience

description: The light weight and ductility offered by cold-formed steel- (CFS) framed building systems aligns precisely with the system resiliency needs in moderate to high seismically active regions. However, the use of CFS framing for construction of mid to high-rise structures in the North American construction industry is severely restricted due to a lack of available full-scale system level test data documenting both earthquake and post-earthquake fire response. To fully utilize this form of construction and meet the growing needs of urban housing needs, a 10-story CFS-framed building is planned to be tested under increasing earthquake hazard scenarios, followed by live fire testing, at the NHERI 6-DOF Large High-Performance Outdoor Shake Table (LHPOST6) facility at University of California, San Diego. ​​This experimental program is also complemented with numerical models to provide predictions of the test building seismic behavior, guiding earthquake motion selection and scaling which define the  test protocol.

The test building, coined CFS10 (cfs10.ucsd.edu), will integrate architectural finishes and will be the first to have a 100ft building height, exceeding current height limitations (6-stories or 65ft), set by present ASCE 7 design standards. The building design advances the lateral force resisting system (LFRS) details to provide for the increases in shear and overturning moment demands due to the increase in building height. Additionally, the experimental program offers an exciting opportunity for collaboration between researchers and industry partners to bring forth new ideas to realize modular construction within CFS framing systems. The test building will explore a variety of construction methods, namely, conventional stick-framing (1D), panelized (2D), and volumetric (3D) modular construction within one building specimen, allowing a unique opportunity to document and compare the efficiency of each construction method. The test will also provide a valuable opportunity to examine the evolution of damage of different nonstructural components and systems within a building and develop accurate fragility information, which can be used to improve loss and downtime predictions and evaluate the functional recovery performance. The CFS-NHERI capstone experimental program will generate valuable knowledge which accrues benefits not just for CFS-framed systems, but all systems. Benefiting from extensive partnerships and support from industry, this program offers direct support for advancing design guidelines and construction practices.

title: Vision-based Vibration Monitoring Using Existing Cameras Installed Within a Building: Data Reuse Study from the BNCS Project
title: in System Identification using Surveillance Camera Videos

description: Surveillance cameras are ubiquitous within modern buildings and can be leveraged to extract meaningful data useful for system identification and structural health monitoring. The goal of this study was to demonstrate that the fundamental period of a structure could be accurately estimated by tracking natural features within surveillance camera footage. This project reuses videos (data) captured with internal cameras during previous full-scale shake table test conducted on the Large High Performance Outdoor Shake Table (LHPOST) at the University of California San Diego (UCSD) as part of the building nonstructural components and systems (BNCS) project (Hutchinson et al., 2012). The experimental data published here can be used by others to evaluate computer vision algorithms, system identification algorithms, and structural health monitoring approaches.
description: Videos acquired from the full-scale five-story reinforced-concrete fixed-base (FB) building tested on UCSD's LHPOST as part of the BNCS project were analyzed. The extracted pixel coordinates of natural features in the videos are published here, along with the power spectral densities for fundamental period estimation. This data can be used for vision-based tracking validation, system identification, or structural health monitoring.
