title: Residents’ immediate Response to the 2023 Maui Wildfire
title: in NSF#2345642 RAPID/Collaborative Research: Integrated Sociotechnical Investigations of the Compounding Impacts of Maui Wildfires fueled by Hurricane Dora

description: This project investigates human decision-making and the role of infrastructure during the rapid and devastating Maui wildfire, which was fueled by a hurricane in August 2023. The study is driven by three key factors: Maui’s significant tourist population, which may react differently to warnings and evacuation instructions; the failure to activate any of the island's 80 warning sirens; and widespread cell and power outages that severely limited access to official alerts. The research team analyzed data on residents' behavioral responses, focusing on varying levels of warning information and the impact of critical infrastructure failures, such as damage to transportation, power, and communication networks. 

A survey of 660 survivors highlighted the catastrophic effects of these failures, with only 20% receiving warnings via telecommunications due to power and signal outages, 51% of them saw the wildfire coming, 24.5% saw others evacuated, 13% face-to-face warning from peers. Despite the lack of clear evacuation instructions, many participants displayed remarkable resourcefulness in determining evacuation routes, destinations, modes of transport, and preparation. However, that only 16.2% of people have a family emergency plan and 20% of respondents took more than 30 minutes to prepare for the evacuation indicates the gaps in preparedness level. While 75% of respondents evacuated by own vehicle, 13% of them evacuated by foot. 12% went to a public shelter, 25% went to a public place, 27% went to a relative's house, and 26% went to a friend's house.

The wildfire experience significantly influenced residents' risk perception, preparedness, and information-seeking behaviors. These findings provide valuable insights for improving disaster preparedness, response, and mitigation strategies. Additionally, the team developed an agent-based evacuation model using the collected data to evaluate and optimize warning systems and planning strategies, offering critical guidance for future emergency management policies.
description: This project for Rapid Response Research (RAPID) project collects ephemeral data to better understand the compounding impacts of Maui wildfires and Hurricane Dora and reveal residents' behavioral responses as affected by infrastructure failures. It examines the sources of warning information, protective action decision-making, and evacuation logistics at the individual level. In the meantime, the project captures the operation states of disaster warning operations in Maui under the loss of cell and electric power services. Failures at each system are documented, as well as the cascading effect among inter-connected infrastructure systems. The research outcomes expand the existing body of scientific knowledge on warning and evacuation while advancing the understanding of informal networks and decision-making in the absence of official guidance.

title: Best Practices for Publishing Reproducible Simulation Datasets in DesignSafe

description: A working group of simulation researchers and data curators convened to create guidelines for publishing simulation datasets in DesignSafe. The guidelines reflect the modeling community needs and are informed by the experience of the working group members and the larger DesignSafe expert cohort. These best practices focus on attaining published datasets with precise descriptions of the simulations’ design, complete publication of inputs and if possible, of all outputs, and references or access to the research software/code involved in the simulation. Tying these pieces together requires documentation to understand the research motivation, origin, processing, and functions of the simulation dataset in line with FAIR principles. In crafting these best practices, we specifically considered the characteristics of simulations conducted within the natural hazards space, as well as the data model that drives the interactive simulation curation and publication pipeline and the simulation and analysis tools available in Tools and Applications in DesignSafe. And yet, these best practices can also be used by simulation researchers in any domain to curate and publish simulation data in any repository. In this first version the report does not address Machine Learning /surrogate models. This is a working document that will evolve as we observe how best practices are implemented, and gain experience from new publications and community feedback. We expect researchers publishing simulations in DesignSafe to follow the guidelines, which are reinforced in the curation and publication pipeline.

title: Risk Communication in an Age of Misinformation: Emergency Manager and Household Perspectives Pre- and Post-Disaster

description: The goal of this study is to produce risk communication strategies that align household preferences with emergency management practices before and after a hazard event in today’s era of misinformation. We will collaborate with EM professionals responsible for risk communication – local emergency managers and public information officers – across the study area to co-produce an updated risk communication guide. The study area encompasses communities within the 18 counties, from Orange to Cameron County, along the entire Texas coast. Information collected in the study area from EM professionals as well as the public and the media will be used to evaluate how household information use, preferences, attitudes (e.g., trust), and needs align with EM risk communication practices. Survey experiments will test the effectiveness of various risk messaging across different information channels, including social media, and on compliance with protective action recommendations. This will provide an evidence base to update and refine EM risk communication strategies so that the best language and channels are used to convey risk messages while building trust in EM communications and debunking misinformation.

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: An open access human-induced load dataset

description: Vibration serviceability and safety problems due to human-induced loads are becoming more and more significant for designing light structures such as long-span floors, pedestrian bridges and cantilever stands. Experimental records are very important for understanding dynamic properties of the loads and for developing reliable mathematical load model.  This project provides 3518 records of human-induced loads, mainly including walking, jumping and bouncing loads of individual and crowd. Researchers and engineers can use the database to better solve practical problems by time history analysis. It’s also expected that the database can foster collaboration among researchers and deeper the understanding of the mechanisms of human-induced loads.

title: StEER - 15 December 2019 Earthquake in the Philippines: Event Briefing

description: On December 15, 2019, at approximately 2:11 pm local time, a magnitude 6.8 earthquake, with a depth of 22.4 km, struck 6 km south of Magsaysay, Philippines. It was the fourth big earthquake (magnitude > 6.4) to hit the region within the past two months. The four big earthquakes have collectively resulted in at least a dozen shaking-related fatalities, over 150 injuries, building collapses and significant damage in the region. Such frequent occurrence of large intensity earthquakes is a very rare case and likely had impacts on the performance of the structures in the December 15th earthquake. The objectives of this event briefing are to: 1) provide details of the earthquake hazard, 2) describe damage to buildings and disruption to the community in terms of fatalities, injuries and economic losses, and 3) identify key lessons learned. Information provided herein was gathered from various websites, news channels, USGS and the Philippine Institute of Volcanology and Seismology. Therefore, this briefing does not include insights from detailed field investigations.

title: Efficient seismic fragility functions through sequential selection

description: Fragility functions enable the assessment of a structural system for a given hazard scenario. Specifically, the fragility function provides the probability of an undesirable structural state conditioned on the occurrence of a specific hazard level. Multiple sources of uncertainty are present when estimating fragility functions, e.g., record-to-record variation, uncertain material and geometric properties, model assumptions, and limited data to characterize the hazard. The objective of this study is to develop a methodology that will accelerate the process of fragility function estimation under limitations in computational resources and data. The approach used in the methodology is as follows. The stochastic map between hazard level and structural response is first constructed using Bayesian inference for a finite number of simulations. The Bayesian approach enables the quantification of the epistemic uncertainty due to a limited number of simulations. This epistemic uncertainty is exploited to sequentially select subsequent simulations that accelerate learning based on up to two different earthquake intensity measures, peak ground velocity and spectral velocity. The methodology is applied to a benchmark model of a twenty-story nonlinear building. Simulations are performed using a set of synthetic ground motions obtained from scenario earthquakes  in California. Through this case study the methodology developed here is demonstrated. Additionally, the case study highlights the ability of the methodology to achieve lower levels of epistemic uncertainty than traditional techniques using the same number of simulations. This approach is expected to enable more efficient fragility function determination.

title: Shake table tests on one-story reinforced masonry wall systems
title: in Collapse Simulation of Shear-Dominated Reinforced Masonry Wall Systems

description: Two full-scale, single-story, fully grouted, reinforced masonry wall specimens were tested to the verge of collapse. Each specimen had two T-walls as the seismic force-resisting elements and a stiff roof diaphragm. The second specimen had six additional planar walls perpendicular to the direction of shaking. The two specimens reached maximum roof drift ratios of 17% and 13%, without collapsing. The results can be used to assess the accuracy of the shear strength formula in TMS 402/602. The test data are also useful for calibrating and validating computational models.
description: Seismic design codes have to ensure that buildings have a low probability of collapse in the event of a severe earthquake. To develop such standards, the ability to assess the collapse margin ratios of building systems designed according to given specifications is of critical importance. Under severe seismic forces, reinforced masonry (RM) wall structures may develop complicated nonlinear behavior involving interaction between steel and masonry. Furthermore, the interaction of structural walls with other elements in a building system could lead to nonlinear behavior and collapse mechanisms that were not anticipated in design, including behavior dominated by diagonal shear cracks. The ability of analytical models to capture these mechanisms and interactions is crucial for an accurate assessment of the collapse potential of a building. The main aim of this project is to obtain necessary experimental data to understand the behavior of RM wall structures to the point of collapse, and to use the data to advance and validate refined as well as simplified analytical modeling methods. 
In this project, experimental and numerical studies will be carried out to quantify: (1) the influence of wall flanges on the shear strength and ductility of RM walls; (2) the influence of the coupling forces introduced by horizontal diaphragms in a building on the strength and deformation capability of the structural system; and (3) the influence of non-seismic load carrying walls and columns on the drift capacity and collapse resistance. 
For the experimental study, two full-scale one-story RM wall systems are going to be tested to collapse on the outdoor shake table at the UC San Diego NHERI site.

title: Sliding Glass Doors
title: in Lab Tests with Wireless Sensor Network (WSN) system  for the characterization of strong wind loads on non-structural components

description: This is a full-scale experiment that employed a flat roof box with WSNS installed on four different surfaces.  The main purpose of this test, unrelated to the results presented here, was to evaluate the performance of a storm shield device (unrelated to this project).  The results presented here are concerned with the pressures on sliding glass doors during wind events. The WSNS sensors with aerodynamic casings were attached with Dual LockTM and the SCV patches were hot glued to the surfaces of the glass sliding panes. All sliding doors had glass panels. The sampling rate was 10 Hz and pressure data was measured for different wind speeds 13, 18, 22, and 27 m/s (30, 40, 50, and 60 mph) and two angles (0°, 315°). The duration of measurement for every test condition was 120 seconds. The right-side glass panels on surfaces 1 and 3 are recessed behind the left side panel. The flat roof box had a total height of 3.1 m (125 in). The overall analysis yielded results consistent with the ASCE 7 standard.
description: The goal is to better understand the interaction of hurricane and other strong wind events with non-structural components of residential structures. The objectives are: 1) to develop a new generation of a wireless pressure monitoring system; 2) to deploy the system in large to full-scale tests at the Wall of Wind (WoW); 3) to measure wind pressures on different non-structural components, for different wind speeds and directions;  4) to analyze field and laboratory data to validate and improve current wind loads recommendations and models for pressure distributions on building components.

title: Computing Spectral Acceleration at a Period for traditionally damped SDF system with Fractional Response (Sar-Tnα)
title: in Fractional Order Intensity Measure for High-Confidence Probabilistic Seismic Demand Modeling of Structures

description: Main File for computing Spectral acceleration at a period for traditionally damped SDF system with fractional response (Sar-Tnα)
description: In performance-based earthquake engineering, probabilistic seismic demand models of structures are essential components that provide probabilistic estimates of earthquake-induced demands as a function of a variable(s) called the ground motion intensity measure (IM). Uncertainties in these models are often dependent on the IM used. In other words, an appropriate IM for response prediction play a pivotal role toward reliable probabilistic seismic demand modeling of structures and subsequently, risk and resilience quantification. To this end, a series of novel fractional order (FO) IMs are proposed to release the constraints of traditional integer order IMs such as peak ground acceleration (PGA), velocity (PGV), and displacement (PGD), etc., to yield improved demand models. The developed FO IMs include peak ground response (PGRα), cumulative absolute response (CARα) and its modified version (CAR5α), spectral acceleration at a period of interest for a fractionally damped single degree of freedom (SDF) system (Sad-Tnα) and for a conventional SDF system with fractional response (Sar-Tnα), spectrum intensity for a fractionally damped SDF system (SIdα), as well as for a conventional SDF system with fractional response (SIrα). Superiorities of the developed FO IMs to the traditional IMs are successfully demonstrated using a coupled soil-bridge models considering liquefaction and laterally spreading effects. This demonstration motivates further investigation of these FO IMs for different types of structures or infrastructure systems where introduction of fractional order intensity measures may similarly help to improve performance predictions. Accordingly, seismic risk estimates founded upon the use of these novel IMs have the potential to enhance the confidence and accuracy in future studies.
