title: Establishing a Social Research Infrastructure for Hazards and Disaster Studies - Quebec Canada

description: This project aims to comprehensively map existing hazards and disaster educational programs and resources in the post-secondary institutions in Quebec, Canada. Dataset was collected from the official websites of 135 colleges and 18 universities. The dataset includes: (1) description of the college or university, (2) website and address, (3) courses that focus on risks, hazards, and disasters, and (4) academic programs that address risks, hazards, and disasters. The original data also indicate faculty members who have expertise in conducting hazard and disaster research. However, faculty members’ data (e.g., names, email addresses, and office telephone numbers) cannot be shared publicly due to privacy and ethical concerns. This dataset can be used to compare and illustrate the differences in the current level of hazards-and-disasters-specific-post-secondary educational resources, which in turn, can encourage academic institutions and educators to address the existing gaps and explore possible solutions. The dataset can also be used by current and future students in identifying potential hazards and disaster programs and courses.

title: in NHERI@UTexas Proof-of-Capability Testing Workshop: In-Situ Liquefaction Tests of Columbia-River Sand and Silt Deposits

description: Natural Hazards Engineering Research Infrastructure Equipment Facility at the University of Texas at Austin (NHERI@UTexas) hosted a two-day workshop (June 23th  and June 24th, 2016) on in-situ liquefaction testing at Portland, OR.  The workshop started at 3 pm on June 23th at the Residence Inn by Marriott Portland Airport with presentations from Professors Kenneth H. Stokoe, II and Brady R. Cox from NHERI@UTexas and Professor Armin W. Stuedlein from Oregon State University.  The lectures provide an overview of our NHERI@UTexas equipment, explore research opportunities and challenges, discuss specific details toward developing proposals for the NSF Engineering for Natural Hazards (ENH) program, and the geology of the Willamette and Columbia River Valleys. A field demonstration of an in-situ, proof-of-capability liquefaction test was held in the morning of June 24th at the Port of Longview at Longview, WA. One of the large-mobile-hydraulic NHERI@UTexas shakers, named T-Rex, was utilized to generate dynamic horizontal loading on the ground surface, while the subsurface response of silty soils were monitored with push-in vibration and pore pressure sensors. The objective of the workshop was to showcase the capability of NHERI@UTexas equipment in situ the liquefaction susceptibility of naturally-occurring silty soils in the Willamette and Columbia River Valleys. The site is located immediately north of the Columbia River at the Port of Longview.
description: Geotechnical site investigations at the project site include: (1) ten Cone Penetration Test (CPT) soundings to identify site layering and to develop two, perpendicular site cross-sections, (2) two direct-push crosshole seismic tests to develop constrained compression wave velocity (VP) and shear wave velocity (VS) depth profiles, and (3) two large-scale, in-situ shaking tests with the vibroseis T-Rex to evaluate the relationships between cyclic shear strain and the generation of excess pore water pressure of the natural soils.

title: in Elevated Collapse Risk Based on Decaying Aftershock Hazard and Damaged Building Fragilities

description: This paper proposes a framework to support post-earthquake building safety and reoccupancy decisions by quantifying the change in building collapse risk following a mainshock earthquake event. This risk may be exacerbated by both an increase in seismic hazard due to aftershock activity and a reduction in building collapse resistance due to structural damage. To address these factors, the framework is based on a hazard that includes (a) both the steady state and the aftershock occurrence rates, i.e., the elevated hazard that accounts for the dependence on the mainshock magnitude and the aftershock rate that decays over time, and (b) revised collapse fragility functions that account for structural damage sustained during the
mainshock. The framework is capable of addressing region-specific questions such as: (1) What are the mainshock magnitudes for which aftershocks pose a life-safety concern? (2) How long does it take for the elevated risk due to aftershocks to
dissipate? and (3) What gaps in current knowledge deserve further attention from the earthquake engineering and seismology communities? The framework addresses these questions for a 20-story building in San Francisco, assuming three different,
hypothetical mainshock events of magnitudes 7; 7:5; and 8MW on the San Andreas fault. This is followed by a parametric study that considers a range of buildings and provides a graphical representation of the elevated risk to inform building evaluation (tagging) decisions, based on the intact building’s collapse capacity, the amount of structural damage, and the length of time after the mainshock.
description: These simulations support the calculations in the companion paper that proposes a framework to support post-earthquake building safety and reoccupancy decisions by quantifying the change in building collapse risk following a mainshock earthquake event.

title: Wall Boundary Element Test #9
title: in NEESR: Seismic Performance of Conventional and Innovative Special Structural Walls

description: Uniaxial test of a reinforced concrete wall boundary element #9
description: The project explored design and performance limits for structural walls, considering both conventional wall construction practices and innovative construction practices. A principal finding of recent earthquakes (in 2010 and 2011) and laboratory tests from 200 to 2010 is that wall performance is limited by stability and ductility capacity of the flexural compression zone. Given this critical issue, a series of studies on conventional walls and boundary elements constructed with innovative materials (HPFRCC) to establish performance limits for flexural compression failures in reinforced concrete structural walls. Tests were designed to acquire knowledge, improve construction practices, and advance simulation tools. The primary research outcomes include: 

(1)	Completing  tests of eight ordinary boundary element (OBE) prisms at UCLA. The test specimens were detailed according to ACI 318-11 21.9.6.5 with the goal of assessing failure modes and strain capacities as influenced by concrete cover, configuration of transverse reinforcement, and spacing of transverse reinforcement. Based on the tests, a relationship used to assess buckling of longitudinal reinforcement was extended to wall boundaries with typical OBE detailing. 
(2)	Completing tests on 13 special boundary element (SBE) prisms at UC Berkeley. The tests investigated the role of boundary element detailing and wall thickness. The tests indicated that the strain capacity of relatively (< 12 inches) walls with ACI 318 code compliant SBE detailing was less than one percent and that improved detailing or high-performance, fiber-reinforced concrete did not improve the strain capacity significantly. 
(3)	Conducted tests on seven, approximately one-half scale wall panels represented the base of roughly 8 to 10 story walls in a moderately tall building.  The primary test variables were the configuration and quantity of boundary transverse reinforcement, the depth of the neutral axis, and the wall thickness. The test provided essential data to develop a new, displacement-based model for predicting the drift capacity of structural walls with SBE. 
(4)	Developing code change proposals that were approved for ACI 318-14 and additional code change proposals that have been approved for inclusion in ACI 318-19. 
(5)	Creating and documenting a detailed dataset that was uploaded to DesignSafe-ci Data Depot that can be used for future reserarch.

title: Optimization Model
title: in Design Models for Building Structures with Controlled Rocking Steel Braced Frames

description: Structural control systems are regarded as momentous technologies boosting the development of smart structures and have been the center of attention for improving the safety against natural hazards in recent decades. Among different structural control configurations, Controlled Rocking Steel Brace Frames (CRSBFs) are of the modern systems recently proposed to be used in building structures. CRSBFs are known for their effective energy dissipation and self-centering features. Post Tensioned (PT) strands and shear fuses are the distinct features respectively providing the self-centering and energy dissipation mechanisms in a CRSBF. In this project, an optimal performance-based control co-design framework for CRSBFs is developed. The framework is evaluated using the example of a 6-stroy 3D building structure. The Neural Dynamic (ND) model of Adeli and Park is utilized for the design optimization problem. The objective function is comprised of two normalized terms to account for the main frame weight and the overall cross-sectional area of the PT strands. The minimization of the objective function is then subjected to several constraints based on design code requirements. To evaluate the seismic performance, nonlinear time history analyses are carried out considering the collapse prevention performance level and maximum considered earthquake level. The design optimization model as well as the structural simulation scripts are provided. The numerical outputs for the optimization and structural models are also included.
description: In this model, the design variables of the CRSBF are optimized and the variation of the design variables and objective function is recorded.

title: Defining Appropriate Fragility Functions for Oregon Lifelines

description: This project contains the research report on fragility function database developed for Oregon lifelines (transportation systems, electric power systems, water and wastewater systems) for hazards specific to Oregon (earthquake, tsunami, landslide, liquefaction, winter storm, etc.). The research study was solicited by the Cascadia Lifelines Program (CLiP, https://cascadia.oregonstate.edu/), which is a  research cooperative of Oregon- based lifeline providers.  Objectives of the study included the following: (i) identify available and missing fragility functions suitable for Oregon lifelines, (ii) evaluate the quality of the collected fragility functions, and (iii) provide recommendations where refinement is needed for future fragility function development studies. Based on an extensive literature review and expert solicitation, a fragility function database was structured using a hierarchy of infrastructure systems (electric power systems, water and wastewater systems, and transportation systems), hazards (earthquake, tsunami, etc.), and fragility function attributes (fragility development method, probabilistic distribution, damage states, and other relevant metadata like infrastructure description, regional applicability, and source reference). The resulting database includes fragility functions from publicly available sources, such as HAZUS (FEMA 2010), INCORE (van de Lindt, 2019), SYNER-G (SYNER-G, 2013), the Portland Bureau of Environmental Science (BES, 2018), and other published literature. The database and related web-based user interface may prove useful to Lifeline Engineering  researchers and utility managers to assess risk and make informed decision about their facilities.

title: Data collection of damage to Puerto Rico's infrastructure due to Hurricane Maria and the 2019-2020 earthquakes
title: in RAPID: Multi-Hazard Damage to Puerto Rico’s Infrastructure - Investigation of the Interaction of Hurricane and Earthquakes

description: This project aims to identify the compounding impacts of 2017 Hurricane Maria and the 2020 Earthquake series.  Traditionally, post-disaster damage assessment activities focus on one hazard and overlook the potentially destructive cascading effects of multiple hazards on structures and infrastructure. This project provides data resulting from field reconnaissance emphasizing multi-hazard effects and interactions. The data set includes geotagged pictures, Lidar scans, 360 degree videos and images, UAS videos and images from a first wave of field investigation. Infrastructure surveyed includes port facilities, buildings (particularly historical structures), and bridge infrastructure. This data can be used to understand how the impacts of Hurricane Maria, along with infrastructure aging and delayed recovery or repair activities, may have influenced the damage level and failure modes observed during the earthquake sequence.
description: The aim of this reconnaissance activity was to investigate the potential interaction of two separate extreme events that affected the island of Puerto Rico. The first event was Hurricane Maria in 2017, and the second was a series of earthquakes that occurred in late 2019 and early 2020. The focus of the data collection remained on regions, structures, and elements that experienced the impacts of both events. Therefore, the focus of the reconnaissance was on the south side of the island. The data collection methods included a damage assessment survey, multiple image types, UAS image and video, and Lidar scan data.

title: 2022 Hurricane Ian predictive and post-storm survey instruments
title: in Public longitudinal panel surveys collected during and after hazardous weather threats: Hurricanes

description: These two survey instruments were developed and used to collect longitudinal panel survey data (i.e., repeated surveys of the same people) for Hurricane Ian in 2022. The predictive waves survey instrument was rapidly deployed and fielded three times over the course of a few days as the hurricane was threatening and approaching landfall. Each wave was fielded for approximately 24 to 31 hours with a 20- to 24-hour interval in between. The post-storm wave survey instrument was fielded one time after the hurricane dissipated. It was fielded 14 days after the final predictive survey wave, and it was fielded for 11 days.
description: These are novel datasets of longitudinal panel survey data (i.e., repeated surveys of the same people) when a hurricane is threatening and approaching landfall in the mainland U.S. and after the hurricane has dissipated. Three survey waves were collected pre-landfall when the hurricane was threatening (the threat / predictive phase), and one survey wave was collected post-storm (post landfall or dissipation). The three waves of data collected during the predictive phase measured what forecast and other risk information respondents were getting, respondents' risk perceptions, and respondents' protective behavioral responses, all pertaining to the hurricane risks at that time. The data collected during the post-storm wave correspondingly measured what forecast and other risk information was most useful and what people's actual experiences were with the hurricane. Such rapidly deployed, event-based, repeated-measure data for hurricanes are novel. This project includes datasets for the following hurricane events: Hurricanes Laura and Marco in 2020, Hurricane Henri in 2021, and Hurricane Ian in 2022.
