title: Rensselaer Polytechnic Institute Centrifuge Experiments of the Seismic Interaction of a Liquefiable Soil with a Cantilever Retaining Wall
title: in LEAP-RPI-2020: Seismic interaction of a liquefiable soil with a cantilever retaining wall

description: The Liquefaction Experiments and Analysis Projects (LEAP) is an international collaboration to develop a databank of high-quality centrifuge experimental data and to use this data in calibration and validation of numerical tools of soil liquefaction and associated consequences. LEAP-2020 investigated the performance and seismic interaction of a liquefiable (Ottawa sand) soil with a cantilever retaining wall. A total of twenty-three centrifuge model tests were performed at eight centrifuge facilities, as part of a round robin testing program. The experimental results of these tests are published and shared in this archive as eight separate experiments (one experiment per centrifuge facility). Each “experiment” includes a number of tests and each model test includes one or multiple destructive input excitations. The conducted tests cover a broad range of soil relative densities and input motion conditions. These tests provide valuable information on the trends and sensitivity of the soil-retaining wall response to variations in shaking intensity and soil relative density. The eight centrifuge facilities involved in LEAP-2020 program included Ehime University (Japan), KAIST (Korea), Kyoto University (Japan), National Central University (Taiwan), Rensselaer Polytechnic Institute (USA), University of California Davis (USA), University of Cambridge (UK), and Zhejiang University (China). The “Experimental Data Archive Overview” document provides an outline of the associated organization.
description: Five centrifuge tests (RPI9, RPI10, RPI11, RPI12, RPI13) were conducted at Rensselaer Polytechnic Institute (RPI) to evaluate the seismic response of sheet-pile retaining structures in liquefiable soil for the 2020 Liquefaction Experiments and Analysis Project (LEAP-RPI-2020).

title: Skagway Landslide Hazard
title: in Skagway Landslide Hazard

description: Rockfalls are a common hazard in steep mountain valleys, especially near Skagway, Alaska, where recent events have threatened public safety and infrastructure. This study identifies zones prone to rockfall by analyzing rock formations, past rockfall deposits, and computer models predicting how rocks travel downslope. This dataset was used to perform kinematic rockfall susceptibility and runout modeling. Our findings highlight high-risk areas and provide insights to improve hazard mitigation, helping protect communities and tourism in the region.

title: Exploring Structural Dynamics Through 3D-Printed Models
title: in 3D-Printing Dynamics Design (3D3) Competition – Fall 2024

description: The 3D-printing Dynamics Design (3D3) Competition intends to train School of Civil Engineering & Environmental Science (CEES) undergraduates at the University of Oklahoma in fundamental concepts related to vibrations, structural dynamics, and earthquake engineering through a semester-long, hands-on competition run in parallel with Introduction to Dynamics for Architectural and Civil Engineers (CEES 3263). Competition participants, or 3D3 Scholars, design, build, and test a bench-scale shake table using 3D-printed components. The designs of these shake tables are published here, along with all the STL files needed for teachers or students elsewhere to fabricate the tables. Also, the data collected during the challenges is published.
description: This report evaluates the dynamic response of structures using designed 3D-printed components. It is divided into four challenges, where each addresses different aspects of structural dynamics. Challenge 1 involves designing a wheel that can achieve a low angular acceleration, while exploring the principles of rotational motion. In Challenge 2, a shake table is created using a reciprocating motion system machine to convert rotational motion into linear or ground motion beneath a structure. Challenge 3 includes various free vibration tests conducted at a targeted natural frequency, achieved through the design of structural columns. Finally, Challenge 4 builds upon what was done in Challenges 2 and 3, by testing the structure’s displacement and transmissibility when subjected to forced vibrations generated by the shake table in Challenge 2.

title: Jupyter notebooks for Wind Tunnel & Field Wind-Structure Interaction

description: Florida Tech (FIT) teams deploy networks of wireless sensors on residential houses during high impact wind events or on full scale wind tunnel models. Each deployment might include pressure, temperature and humidity sensors alongside different anemometers and a conical scanning infrared LIDAR. The workflow, starts with uploading the data to DesignSafe through authentication tokens created in Tapis. Once on DesignSafe, three Jupyter notebooks process and visualize the instruments data for analyses. The notebooks provide a user friendly and interactive environment that can adapt to different datasets. For this project, the notebooks perform quasi static real-time analysis, assess sensor performance, study pressure variations for different wind conditions and data correlation. The user interactivity of these notebooks facilitates an easy adaptation to different datasets with little to no-change in code.

title: Longitudinal Social Vulnerability Data Exploration for Harris County Census Tracts

description: Pre-existing social and economic conditions can facilitate or limit a neighborhood’s access to resources, policy making processes, and ability to reap benefits from policy outcomes (McDermott et al., 2013; Beatley, 1989). Extensive research has shown that socially vulnerable populations (ex: minority, elderly, single parent households, households without vehicular access) face more loss during floods and bore longer recovery periods (Peacock et al.,2014; Van Zandt et al., 2012). Thus, while developing policies to address vulnerability to flooding, a critical first step is to assess current and historic social vulnerability conditions in affected areas. 
The goal of this project is to create a workflow that would enable researchers to automate this assessment. We use publicly available census tract level social vulnerability data for 2016, 2010 and 2000 in Texas from the Centers for Disease Control. This workflow uses STATA program to first download social vulnerability data. Next, we clean and append data files to facilitate statistical analysis. Finally, we use mapping tools to explore the data set. The resulting CSV data file can be used for longitudinal analysis of social vulnerability data in Texas census tracts from 2000 to 2016.

title: Nonlinear analysis of strongback braced frames for evaluation of design methods
title: in Evaluation of Methods of Design for Strongback Braced Frames

description: Nine (9) strongback braced frames (SBF) were designed for three buildings using three different design methods: simplified modal pushover analysis (SMPA), generalized modified modal superposition (GMMS), and a "control" procedure based on current standardized response spectrum analysis and capacity design procedures (RSAC). Nonlinear static pushover and nonlinear dynamic analyses were performed against the resulting designs. The designs were then analyzed with modified strength and stiffness of the strongback.

Summarized data from the analysis, as well as complete source code for re-running the analyses and re-creating the plots, are provided.

title: in Research on COVID-19 Disaster Researchers

description: The purpose of the project is to systematically study and document the impacts of the pandemic on this group of researchers who were themselves affected by and researching COVID-19. To do so, we conducted 30 qualitative interviews at two points in time between 2020 and 2022 to address four research objectives: 1) To illuminate how researchers are drawing upon existing theoretical frameworks and concepts to develop innovative ways to apply existing knowledge as they navigate this new territory; 2) To understand how researchers are collaborating and networking through the pandemic; 3) To determine ways in which the current and ongoing situation is influencing researchers’ thinking about disaster research; and 4) To learn how the COVID-19 pandemic is affecting researchers both professionally and personally.
Data from this project can be used by other researchers interested in studying how researchers do research, particularly when they are part of the situation they are attempting to study. Findings can be used to better prepare employers and the research community for future pandemics or unexpected disruptions.

title: Design options and risk calculations for seismic isolation systems in advanced nuclear reactors
title: in Implementing Seismic Base Isolation in Advanced Nuclear Reactors

description: This simulation project supports a topical report, to be submitted to the NRC, that presents a risk-based pathway for implementing an isolation system in an advanced nuclear reactor. The project includes numerical models, constructed in SAP2000, that were used to support the risk calculations presented in the topical report and to illustrate the options available to engineers and analysts designing an isolation system for an advanced nuclear power plant.
description: Seismic isolation represents a pathway to the standardization of advanced reactors. An established regulatory pathway to incorporate seismic isolation into an advanced nuclear power plant will be invaluable for those seeking a license from the US Nuclear Regulatory Commission (NRC). A topical report, funded by the US Department of Energy through its Industry Opportunities for Advanced Nuclear Technology Development (Industry FOA) program, was written to provide a risk-based pathway to implement seismic isolation systems in advanced nuclear reactors. To illustrate the proposed pathway, calculations were made using multiple numerical models that were constructed in the finite element package, SAP2000. These models are made available here and intended to aid end users of the topical report, including analysts designing isolation systems for buildings in general, and nuclear power plants in particular.

title: StEER: 10 December 2021 Midwest Tornado Outbreak Joint Preliminary Virtual Reconnaissance Report and Early Access Reconnaissance Report (PVRR-EARR)
title: in StEER - 10 December 2021 Midwest Tornado Outbreak

description: In the late hours of 10 December and into the early hours of 11 December 2021, unseasonably warm air instigated an outbreak of at least 60 confirmed tornadoes across nine states. The outbreak included a family of damaging “Quad-State” tornadoes, with an EF4 tornado that was on the ground for over 160 miles causing devastating impacts to many small communities and in particular Mayfield, KY. This tornado outbreak is expected to be one of the largest and deadliest tornado events in US history. 
Given the historic nature of this outbreak, StEER immediately issued a Level 3 response to this event, simultaneously activating its Virtual Assessment Structural Team (VAST) on 11 December, while, its Field Assessment Structural Team (FAST) was assembled to begin collecting perishable data in Mayfield and surrounding areas on 14 December. This project encompasses the products of StEER's response to this event: a joint Preliminary Virtual Reconnaissance Report-Early Access Reconnaissance Report (PVRR-EARR) and Curated Dataset.
description: This is first product of StEER's Level 3 response to the 10 December 2021 Midwest Tornado outbreak culminated in a single joint PVRR-EARR, a hybrid of StEER’s standard Preliminary Virtual Reconnaissance Report (PVRR) and Early Access Reconnaissance Report (EARR): (1) summarizing the genesis and hazard characteristics of these tornadoes, (2) providing an overview of the regulatory environment in Kentucky, (3) outlining StEER’s field response and reconnaissance methodology, (4) documenting the performance of a wide range of buildings and other  infrastructure, and (5) recommending topics worthy of continued study by the natural hazards engineering community and affiliated fields. The PVRR-EARR includes both the official report as well as a supplementary media repository containing additional imagery gathered by the VAST. The report is a combination of both virtual reconnaissance by StEER's VAST and field investigations by StEER's FAST.

title: Thornton Tomasetti's reconnaissance mission data collection
title: in Field Data and Observations of Damaged Buildings Ten Weeks after the February 2023 Earthquake Sequence in Türkiye

description: Field reconnaissance mission to south-east Turkiye to the affected area of the February 2023 earthquake sequence. The mission focused on collectin data around three objectives:
(1) observing the performance of modern construction that presumably followed the building code;
(2) collecting data on the impact of “risk category” assumptions or use of base isolation on seismic performance, and 
(3) documenting and identifying trends in the recovery process.
description: The February 2023 earthquakes in Türkiye constitute one of the largest shaking sequences in recent history that has impacted a significant area and vast number of buildings designed per modern seismic design provisions. This paper and associated database present the major observations from Thornton Tomasetti’s reconnaissance team that visited the affected area between April 12th and April 19th, 2023. The team visited 17 cities, drove approximately 2500 km around the rupture, and collected more than nine thousand photos and thirty videos documenting the state of recovery of the community. This mission focused on: (1) observing the performance of modern construction that presumably followed the building code, (2) collecting data on the impact of “risk category” assumptions or use of base isolation on seismic performance, and (3) documenting and identifying trends in the recovery process. At the time of the visit, most collapses had been cleared and demolitions were starting to take place in major urban areas. This condition was ideal to clearly survey the state of severely damaged buildings. As expected, we observed that newer buildings that follow modern earthquake engineering principled (mostly known as post-2000 buildings in Türkiye) performed much better than the pre-2000 buildings. However, infill walls were a common problem for all buildings. These rigid elements participate in the lateral load path complicating the behavior of the building and significantly affecting the seismic performance. In some cases, infills may have been beneficial (e.g., older, seismically deficient buildings) but in others, infills resulted in extensive non-structural damage. In many cases, structural damage appeared minor and repairable but non-structural damage was so prevalent that officials tagged the building for demolition. Per modern codes, these buildings can be considered "successful" since they achieved a "life safety" performance under a very large earthquake. Nonetheless, that “success” led/will lead to demolition of thousands of structures, displacing a large fraction of the population and creating enduring impacts to the local economy and society in general. The curated database with all the photographs and videos collected by this reconnaissance team is openly available in this DesignSafe project.

title: Water Network
title: in Seaside Testbed Data Inventory for Infrastructure, Population, and Earthquake-Tsunami Hazard

description: This dataset contains water infrastructure characteristics for Seaside, Oregon.
description: This project contains datasets associated with Seaside, Oregon, a multi-hazard testbed for infrastructure resilience. Seaside is located along the Oregon coast and is subject to both seismic and tsunami hazards associated with the Cascadia Subduction Zone (CSZ). The Seaside testbed was established as a multi-hazard testbed for the NIST Community Resilience Center of Excellence. The size of Seaside lends itself to parcel-level analyses of multi-infrastructure damage, loss, and recovery modeling. 


Datasets are provided for built-, natural-, and social-systems in Seaside. The built environment consists of buildings, electric power, transportation, and water infrastructures. The building inventory was constructed from tax-lot data, Google street view, and a field survey (Park et al., 2017b). The electric power network was constructed from aerial imagery. Bridges in the transportation network are from the National Bridge Inventory and roads are from the TIGER/Line database. The water network is from the city of Seaside public works (Kameshwar et al., 2019). The natural environment (hazards) are the result of a probabilistic seismic-tsunami hazards analysis (PSTHA; Park et al., 2017a). The social systems consist of results from a housing unit allocation (Rosenheim et al., 2019). Researchers, decision makers, and planners, among others, can utilize these datasets to conduct community-scale multi-hazard risk assessment, focusing on application to the coastal urban city of Seaside, Oregon.

title: Documenting historic buildings damaged by the Quadstate tornadoes in December 2021

description: The 2021 Quad State Tornado outbreak, an EF-4 event with a path length exceeding 250 miles and wind speeds over 190 mph, provided a unique opportunity to assess the performance of historic buildings across multiple states in the American Midwest. This study developed a comprehensive dataset by documenting over 200 historic buildings located within a 2-mile radius of the tornado paths. The dataset was compiled through post-disaster field investigations and archival research, focusing on the original construction materials, techniques, and any modern interventions or retrofits of these historic structures.

title: Research Experiences for Undergraduates (REU), NHERI 2022: Characterization Test of Pressurized Sand Damper Using the Bouc-Wen Model

description: The purpose of this project was to develop a numerical model to simulate the behavior of the energy dissipation device, the Pressurized Sand Damper (PSD). The model used to simulate it was the Bouc-Wen model which consists of eight parameters, from which only 4 of them are dependent on the collected data. Finally, the damper used was able to be put to the test through the model to validate its efficiency using the index values of displacement and acceleration reduction in a three-story building. The PSD represents the future of earthquake engineering as a low cost yet effective damper. Therefore, the objective of the created model is to be used as an accurate representation of the behavior of the actual PSD to put it to the test in researchs of different scenarios with different magnitudes.
