title: Aeroelastic Testing of a standalone transmission tower with a height of 59.75m - Undamaged Case
title: in 186n-Downburst_Transmission_Tower

description: The transmission tower is a steel-lattice-type cat-head overhead tower commonly incorporated in 110 kV, 150 kV, 220 kV, and 500 kV transmission lines. It has a height of 59.75m (196ft) with a square-shaped base of 13m (42.65ft), comprising four legs. These legs are made of steel single-angle members (L5x5x5/16, “L”-shaped cross-section) presented in Zone 1. The outer shape of the tower is pyramidal-shaped up to the bottom of the cat-head top portion, with a slope of 8:1. The tower is designed to carry three parallel conductors in which two conductors are bundled on each cross-arm, and the third conductor is suspended at the mid-point of the top girder through the cat-head window. 
description: Transmission Line Systems (TLSs) play a pivotal role in modern society by serving as the primary infrastructure for delivering electricity from power plants to residential buildings, healthcare facilities, and industrial zones. The extensive network of electricity transmission towers and power lines spans approximately 640,000 miles across the United States, ensuring nationwide electricity distribution. However, the lengthy nature of these systems makes them vulnerable to extreme weather events such as hurricanes, tornadoes, and downbursts. Downbursts are intense, localized columns of rapidly descending cold air originating from thunderstorm clouds generating powerful lateral winds upon reaching the ground that can cause severe structural damage to TLSs. Of many differences between atmospheric boundary layer (ABL) and downburst winds, the highest wind speed in a downburst event occurs 50m to 100 m above the ground surface, intensifying the wind effects on most structures, particularly TLSs. Additionally, the spatiotemporal effect of downbursts tremendously alters the wind loading on lengthy TLSs, potentially leading to structural failures and disruptions in the electricity supply chain.
A grounding step was to design a scaled transmission tower-insulator-conductor system with a geometric scale of  1:50 in the vertical direction and a distorted scale of 1:150 in the horizontal direction. This design was made in three steps: (1) designing and constructing a damaged transmission tower, (2) designing and constructing an undamaged transmission tower, and (3) incorporating the undamaged transmission tower into a TLS comprising three transmission towers. In each step, the model was tested under ABL and downburst winds, except in step (1), where the model was only tested under downburst winds, as shown in Figure 1. We also included two special test cases to heighten the realism level by simulating non-uniform loading and conductor breakage cases. These testing cases were conducted at NSF NHERI Wall of Wind Experimental Facility (WOW EF).

title: Hazard Resilient Pipeline Research Panel (HRPRP) Report

description: This report presents a process and matrix for utilizing buried hazard resilient pipelines. They were developed by a group of researchers from the USA and Japan who worked to improve the understanding of hazard impacts on buried water pipelines. A wide range of natural hazards, many having increased intensity from climate change, are known to affect the performance of buried water pipelines and the ability of water systems to provide services. Hazards impose strains through different mechanisms (e.g., thermal, ground displacement) on pipelines that may lead to damage. Resilient pipelines are beneficial for managing the strains imposed by a wide range of events. The matrix lists hazards and their potential impacts on buried pipelines, service disruptions, and societal consequences. The matrix helps guide pipeline owners to identify, prioritize, and plan for the use of hazard resilient pipelines. The matrix and an associated process are proposed to be implemented into practice to identify the need for and application of hazard resilient pipeline.

title: Informally-Constructed houses under Typhoon
title: in Building Capacity for Safer Post-disaster Shelter: Leveraging Local Understanding and Advanced Engineering Assessments

description: There is an urgent need to improve community capacity to recover more effectively after disasters through safer design and construction practices. To do this, training programs need to foster an improved understanding of shelter design and construction to withstand future wind and earthquake events. This project analyzed perceptions of those working in the informal construction sector of housing safety in Puerto Rico (after 2017's Hurricane Maria and the 2019-2020 earthquake swarm) and homeowner’s perceptions of housing safety in Philippines (after 2013's Typhoon Haiyan and 2017's Ormoc earthquake) to: (1) assess local understanding of shelter safety in multiple hazards, including causal factors influencing this understanding, through a household survey in the Philippines and a survey to of builders in Puerto Rico (Venable et al. 2020; Goldwyn et al. 2021; Goldwyn et al. 2022); (2) assess the expected performance of various post-disaster shelter typologies to quantify safety during future earthquake and wind events using performance-based engineering methods (see citations associated with the data sets); (3) identify conflicts between perceived and assessed safety of shelter, and why these conflicts exist, by comparing engineering assessments with local perceptions (Venable et al. 2021 and Goldwyn et al. 2022); and (4) create and assess a communication design for organizations assisting with training for safer housing construction (Goldwyn et al. 2023).
description: Although organizations build housing in resource-limited contexts after typhoons and other disasters that is intended to be safer than what existed previously, the performance of these houses in future typhoons—and the factors influencing performance—are unknown. This study develops a component-level, performance-based wind engineering assessment framework and evaluates the wind performance of twelve semi-engineered post-disaster housing designs, representing thousands of houses that were constructed in the Philippines after Typhoon Yolanda. We found that roof panel loss likely occurs first for most designs, at wind speeds equivalent to a category 2 hurricane/signal 3 typhoon. Roof shape determines whether this loss is caused by failure at the panel-fastener interface or purlin-to-truss connection. However, houses with wooden frames and woven bamboo walls may also experience catastrophic racking failures at wind speeds equivalent to signal 2 or 3 typhoons, a situation exacerbated by strengthening the roof. Results also show that wind performance varied with roof shape, component spacing, panel thickness, eave length and connection between purlin and truss. Organizations can use these results to improve housing performance, taking specific care to increase wall capacity. This framework can be expanded to assess housing performance in other resource-limited contexts.

title: Research Experiences for Undergraduates (REU), NHERI 2023: Spatio-temporal Testing of Air-Permeable Building Cladding Systems

description: This DMR case study focused on spatio-temporal testing of air-permeable building cladding systems to assess their performance under dynamic wind pressures. The increasing damage caused by hurricanes has emphasized the need for robust building materials and designs. Recent failures, such as soffit and siding failures, have highlighted vulnerabilities in existing construction practices. Using a controlled laboratory testing device called a spatiotemporal pressure-loading actuator (SPLA) simulated wind pressure dynamics on roofing components during high wind events were tested. The data collected from this research can be reused for future development of new buildings, design of new discontinuous metal roofing (DMR), continuing the research left to be worked on, and also as a reference for similar research of projects in the near future. This project can be unique for the scope we were aiming for, which was how efficiently we could test DMR panels and get precise results with fewer error margins while maintaining efficiency and productivity. The audience can be a college student looking to start an internship and using this as inspiration while also helping the student understand what they can expect to learn; another type of audience can be a researcher looking for references on similar topics or testing which there is lots of information to gather from this research and the reference used on this research as well. A final audience this could be directed to would be a professor doing a research project with his graduate student as a reference to guide his student.

title: Six-month Post-tornado Repair Progress: Wave 2
title: in StEER - 28 MAY 2019 LINWOOD, KS EF4 TORNADO: FIELD ASSESSMENT STRUCTURAL TEAM 1 (FAST-1)

description: This mission achieved the human subject research protocols, data collection instruments, and data for the physical repair progress for homes along the tornado path six months after the 2019 EF4 Linwood, Kansas tornado. 144 residential buildings were assessed in Wave 2.
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.
