title: Parametric Study of Earthquake Motions
title: in Simulations of Seismic Displacement of a Clay Slope using LS-Dyna

description: LS-Dyna finite element analyses of a clay slope subjected to 105 different earthquake motions
description: This project includes LS-Dyna finite element models, input motions, and outputs from a study of the earthquake-induced permanent displacement of a clay slope.  The permanent displacements computed from 105 earthquake motions are used to develop slope-specific displacement prediction models. Different prediction models are developed that utilize different ground motion intensity measures.  The results from this study are further analyzed in Cho and Rathje  (2020, https://doi.org/10.1016/j.soildyn.2020.106367) and used to compute probabilistic displacement hazard curves for a site in Northern California.

title: Follow the Money: Using Content Analysis to Understand Disaster Spending

description: Recovery from and mitigation for disasters is not uniform across events or communities. Although there can be commonalities across disasters in terms of recurrent disaster funding streams, financing for disaster management varies by community and hazard event. This poster explores various funding streams and how planning documents such as hazard mitigation, recovery, capital improvement, and comprehensive plans can have codes created for mixed methods of qualitative and quantitative analysis. The typology of codes can represent policies, themes, funding awards, time frame, and track recovery costs, investments, and funding sources through time. This poster applies this method to the case study of Galveston, TX, after 2008 Hurricane Ike to track federal disaster spending on infrastructure, utilities, and facilities. The ultimate aim of this research is to track funding sources and spending and develop a standardized coding process and methodology to facilitate comparisons across different communities, hazards, mitigation, and recovery priorities to identify best practices and broader trends of how recovery resources are utilized in disaster management. Actions, policies, and improvements can be identified to help set a protocol for other cities to follow.

title: Hurricane Dorian Survey Southeast U.S.
title: in RAPID: Investigating Media Dependencies, Mitigation Behavior, and Information Processing in the Time Leading Up to Hurricane Dorian

description: An online survey targeted1,000 residents of coastal areas of Florida, Georgia, South Carolina, and North Carolina in order to assess the key variables of interest. Participants were asked about the relative importance of varying media, sources of first alerts, perceptions of information adequacy, mitigation efforts and damage to their homes, coping strategies, and emotional responses. They were also evaluated in terms of their tendency toward rumination and their trait need for cognition. The aim is to investigate whether particular media dependencies are related to successful mitigation outcomes, and whether or not these outcomes are moderated by individual level information processing characteristics.

title: Learning from Hurricane Harvey: Analyzing Contributions from the Social Science Extreme Events Research (SSEER) Network

description: This project uses data from the Social Science Extreme Events Research (SSEER) network (N=1,230) and examines the characteristics of social scientists who study hurricanes. Hurricane Harvey is utilized as a case study because it stands as one of the most costly disasters in U.S. history and is one of the most often studied events in the SSEER database with about 12% of SSEER members who reported studying this event. This, therefore, presents a special opportunity to explore a primary interest in emerging researchers (students and others new to the field), since they will be at the forefront of disaster research, preparedness, and mitigation efforts in the future. Discovering similarities and differences between researchers of the same event can foster new understandings: What knowledge, skills, and training create the pipeline that leads social science researchers to study extreme events? What role do popular disaster events like hurricanes play in the development of emerging researchers? And what kinds of researchers were most likely to study Hurricane Harvey?

title: Phase 3: Veneer Laminated Timber (VLT) Coupled Self-Centering Rocking Wall (SCRW) with U-Shaped Flexural Plates (UFP)
title: in Emmerson Lab Launch Initiative (ELLI): Cyclic Loading of a Three-Story Building with Lateral Force Resisting Systems (LFRS) using Mass Timber Products and Steel Energy Dissipators

description: This project tests innovative lateral force resisting systems (LFRSs) comprised of newer mass timber products and steel energy dissipation mechanisms. These LFRSs represent a suite of resilient design techniques that can localize damage in special hardware designed to dissipate energy during an earthquake or similar disturbance. The end product is a building that is potentially more resilient to natural disasters than conventional construction. The three-story building in the project is tested in multiple phases, each phase utilizing a different LFRS in terms of design and materials. The experimental data benefit structural engineers, product manufacturers, and building code developers in academic and professional communities. The data can be reused to quantify and compare the structural performance of the LFRS types tested.
description: A lateral force resisting system (LFRS) comprised of two coupled four foot wide Veneer Laminated Timber (VLT) panels with U-shaped Flexural Plates (UFPs) and vertical post-tensioning was attached to the building frame and tested following a cyclic quasi-static loading protocol up to 4% roof drift ratio.

title: Data Report on Household Impact and Recovery Assessment: A longitudinal Investigation after the 2019 EF4 Linwood, Kansas Tornado
title: in StEER - 28 MAY 2019 LINWOOD, KS EF4 TORNADO: FIELD ASSESSMENT STRUCTURAL TEAM 1 (FAST-1)

description: On May 28, 2019, a destructive EF4 tornado struck north-eastern Kansas, resulting in severe damage in Leavenworth County and surrounding areas. The tornado travelled 31.8 miles in 55 minutes and had a maximum width of one mile. There were 18 injuries but no fatalities. The Structural Extreme Events Reconnaissance (StEER) funded a quick response field study, referred to here as Wave 1, to document post-tornado damage to building structures along the tornado path. The Wave 1 survey documented initial building damage, aerial imagery of the tornado path and provides an essential baseline for subsequent impact and recovery studies. A second and third wave of data collection were funded by PI Sutley’s fellowship funding from the National Academies of Science, Engineering, and Medicine Gulf Research Program, and were executed six months and twelve months after the tornado, respectively. The Wave 2 and 3 teams consisted of structural engineering professors and students, behavioral economics professor and students, and public administration and urban planning students from the University of Kansas. Goals for Wave 2 and Wave 3 were to: (1) document risk perception, sheltering behavior, impact, and recovery experience of households during and since the May 2019 tornado, and (2) document the repair progress for homes along the tornado path six and twelve months after a major tornado in rural Kansas. This project achieves collected data from Waves 1, 2, and 3. This collection also archives survey instruments and Institutional Review Board protocol approved by the University of Kansas IRB office for Waves 2 and 3.
description: This report describes the data collection process, and the survey data collected. The data in this publication comes from the second and third waves of data collection after the sixth month and one-year mark of the tornado, respectively. The data consists of the physical structure repair progress photographs and the household repair survey.

title: NSF #1537788: Enabling Next Generation Hybridized Wood Buildings for Resilient and Sustainable Construction

description: In this project, the seismic behavior and optimization of a hybridized self-centering wood system termed a CLT-LiFS that uses unbonded post-tensioning tendons, cross-laminated timber (CLT) rocking walls and light-frame wood systems (LiFS) were investigated to enable the design of tall wood buildings that are sustainable and resilient. In this system, the CLT panel anchored with unbonded post-tensioning are optimally combined with the light-wood frame system to exploit the beneficial features of each. While the unbonded post-tensioning in the CLT will self-center the system, the connections in the light-frame wood will provide the necessary energy dissipation. The studies on CLT-LiFS have shown their very good seismic performance with limit structural damage.

title: Precast Concrete Wall Tests - Grouted sleeve connections
title: in University of Auckland: Precast Concrete Wall Tests - Grouted Connections

description: During the 2010/2011 Canterbury (New Zealand) earthquakes damage was observed to grouted connections used for precast concrete wall panels. A series of experimental tests were subsequently performed to investigate the in-plane seismic behaviour of precast concrete walls with grouted connections. Testing comprised of nine reversed cyclic in-plane tests of full-scale precast concrete wall panels. Seven walls used grouted metal duct connections at the wall-to-foundation joint, with test variables considering panel geometry, axial load, and panel reinforcement.  An additional two walls were tested with grouted sleeve wall-to-foundation connections with both a single and double layer of panel reinforcement.  Test data from these nine precast wall tests is published including wall design, test setup and procedures, clean sensor data, and photos.
description: During the 2010/2011 Canterbury (New Zealand) earthquakes damage was observed to grouted connections used for precast concrete wall panels. A series of experimental tests were subsequently performed to investigate the in-plane seismic behaviour of precast concrete walls with grouted connections.  The two full-scale wall panels with grout sleeve wall-to-foundation connections were subjected to reversed cyclic in-plane demands. Wall failure was characterized by a combination of connection reinforcement pulling-out from the grout sleeve connector and reinforcement fracture. Test data could be used to evaluate the seismic performance of precast concrete walls to develop seismic assessment or design procedures.

title: Shake Table Tests of a Coupled Primary Structure-Floor Isolation System
title: in Experimental Study of the Seismic Performance of a Dual-mode Floor Isolation System

description: A small-scale rolling-pendulum (RP) isolation system with gap restrainers was tested under swept-sine surveys (chirp) of varying amplitude. These tests were used to characterize the properties of the experimental small-scale floor isolation system (FIS) that was subsequently installed in a small-scale three-story primary structure (PS). The PS-FIS system was tested under four historic ground motions through shake table testing. These tests were used to assess the coupling between the FIS and the PS. Additionally, cyclic load-displacement tests were run to characterize the response of the shock absorbers used in the FIS. All the data from these experiments have been processed to quantify the performance and characteristics of the PS-FIS and its components, as documented in the data report and in Bin (2021).
description: Floor isolation systems (FISs) are used to mitigate earthquake-induced damage to sensitive building contents and equipment. Traditionally, the isolated floor and the primary building structure (PS) are analyzed independently, assuming the PS response is uncoupled from the FIS response. Dynamic coupling may be non-negligible when nonlinearities are present under large deflections at strong disturbance levels. This study investigates a multi-functional FIS that functions primarily as an isolator (i.e., attenuating total acceleration sustained by the isolated equipment) at low-to-moderate disturbance levels, and then passively adapt under strong disturbances to function as a nonlinear (vibro-impact) dynamic vibration absorbers to protect the PS (i.e., reducing inter-story drifts). The FIS, therefore, functions as a dual-model vibration isolator/absorber system, with displacement-dependent response adaptation. A scale experimental model—consisting of a three-story frame and an isolated mass—is used to demonstrate and evaluate the design methodology via shake table tests. The properties of the 3D-printed rolling pendulum (RP) bearing, the seismic gap, and the impact mechanism are optimized to achieve the desired dual-mode performance. A suite of four ground motions with varying spectral qualities are used, and their amplitudes are scaled to represent various hazards—from service level earthquake (SLE), to design basis earthquake (DBE), and even maximum considered earthquake (MCE). The performance of the multi-functional FIS is established through shake table tests, and the FIS and its components are characterized through sine sweep tests and load-deflection tests. The experimental data can be used by others to validate models of RP bearings, tune mechanistic models for similar shock absorbers, and evaluate computer vision algorithms for inter-story drift measurements utilizing cameras located within the building.

title: Turkey-Syria Earthquake Impact Estimates from Near-real-time Crowdsourced and Remote Sensing Data

description: The research published in this report utilizes near-real-time data collected from social media platforms and remote sensing data sources to estimate seismic impacts in the 2023 M7.8 and M7.5 Turkey-Syria earthquake, including (1) infrastructure damage, (2) human mobility, and (3) human casualties. More specifically, we provide spatial estimates of building damage probability, communication network outages, evolving reports of casualties in Turkey and Syria, as well as how population density and human movement changed after the devastation. The information may help government and aid agencies as well as first responders better plan their rescuing and recovering activities, and provide research communities with high-quality data to better understand how disaster impacts evolve and how people respond in finer-grained temporal resolution.
