title: Long-term moisture content monitoring of nail-laminated timber bridge deck using Electrical Resistance (ER) method
title: in On-site monitoring of the moisture content of bridge decks made of nail-laminated timbers

description: This study summarizes the moisture content (MC) monitoring results of two nail-laminated timber (NLT) bridge decks in New Brunswick, Canada. The MC monitoring systems were installed in the NLT decks of two newly-built bridges, Clark Mill Pond and Shikatehawk No.5, in New Brunswick, recording the MC through Electrical Resistance (ER) method. The calibration test was conducted to correlate ER values recorded in Ohm with MC in percentage. It was found that the MC values varied from 9.9% to 18.2% and 12.8% to 19.7% for bridge Clark Mill Pond over 239 days and for bridge Shikatehawk No.5 over 189 days, respectively. Based upon these MC monitoring data, the NLT decks could likely not be prone to rotting caused by biotic attack during the monitoring period.
description: A commercially available system made by Scanntronik Mugrauer GmbH (Germany) was used for this study. The on-site monitoring system consists two independent parts: a battery powered moisture meter with eight channels, namely Material Moisture Gigamodule, and a battery powered temperature sensor with two external channels to measure temperature and one internal temperature sensor for air temperature, namely Thermofox Universal. The pins that connected to the moisture meter are Teﬂon-insulated electrodes made by GANN (Germany) with two lengths, 15mm and 25mm, which enable the measurement of moisture content at speciﬁc depths. The system recorded the MC through Electrical Resistance (ER) method. The calibration test was conducted to correlate ER values recorded in Ohm with MC in percentage.

title: Interview guide for RAPID: Understanding Evacuation, Sheltering, and Reentry Decisions During the Dual Threat of Hurricane and the COVID-19 Pandemic
title: in RAPID: Understanding Evacuation, Sheltering, and Reentry Decisions During the Dual Threat of Hurricane and the COVID-19 Pandemic

description: This Grant for Rapid Response Research (RAPID) project documents emergency mangers' evacuation decisions and their sheltering considerations during Hurricane Laura as individuals cope with the COVID-19 pandemic. It is important for the scientific community, policymakers, and emergency managers to understand how the simultaneous threats of a hurricane and a pandemic affect individual and household decisions about protecting themselves during these events. The findings from this project will help emergency managers and policymakers develop appropriate public health and population protection strategies to help communities be prepared for future events. With a better understating of the determinants of hurricane and pandemic protective actions (e.g. evacuation, social distancing, sheltering) compliance, emergency managers can develop better evacuation plans and warning messages to help reduce the impact of both the pandemic and hurricane, as well as to advance national health and welfare.

Here, we provide our interview guide for future replication work.

title: in RAPID: Performance of Reinforced Concrete Structures with Externally Bonded Fiber Reinforced Polymer Composite Retrofits in the 2018 Anchorage, Alaska Earthquake

description: Externally bonded fiber reinforced polymer (EBFRP) composites can be used to seismically retrofit structures in a simple and economical manner. However, lack of documented evidence of their performance during an earthquake still limits their widespread adoption. In this project, the effects of the November 30, 2018, earthquake (magnitude 7.0) in Anchorage, Alaska, on the performance of EBFRP composite retrofits in reinforced concrete buildings, were studied. This study, for the first time, provides information on the performance of EBFRP retrofitted structures in an earthquake that occurred in the United States. 
The main objective of this project is to collect perishable data on EBFRP response during the 2018 Alaskan earthquake to improve understanding of the performance of EBFRP-retrofitted structures. The data collection activities in Anchorage, Alaska, coordinated with the National Institute of Standards and Technology (NIST), included the following: (1) photographic documentation of damage to EBFRP retrofit systems (e.g., delamination, rupture, and environmental degradation), and (2) identification of in-situ characteristics of the EBFRP utilizing non-destructive (e.g., acoustic sounding and infrared thermography) and semi-destructive (e.g., bond pull-off test) methods. Where permissible, small samples of EBFRP were collected for chemical and thermal analysis to determine the extent of environmental degradation in EBFRP.
description: EBFRP samples collected in Anchorage, AK were used for Differential Scanning Calorimetry (DSC)  tests at Center for Composite Materials, University of Delaware. Glass transition temperature was evaluated per ASTM E1356. Glass transition temperatures of interior and exterior samples were compared to investigate the effect of different ambient conditions on thermal properties. Acquired data are an evidence of aging effect on thermal properties of EBFRP.

title: Computing Spectral Acceleration at a Period for Fractionally Damped SDF system (Sad-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 fractionally damped single-degree-of-freedom (SDF) system (Sad-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.

title: Wall Panel Test 1
title: in NEESR: Seismic Performance of Conventional and Innovative Special Structural Walls

description: Reversed-cyclic pseudo static test of reinforced concrete wall panel representing plastic hinge region of a wall
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: Characterization Tests of Rolling Pendulum Isolation Bearings with Different Surface Treatments
title: in Characterization of Rolling Pendulum Isolation Bearings

description: Rolling-pendulum (RP) isolation bearings with different surface treatments were tested under quasi-static, harmonic, and simulated earthquake-induced motions. These tests were used to characterize the behavior of the RP bearings, including the gravitational restoring force and the rolling resistance associated with the elastomeric coatings of different thicknesses. The experimental data from analog sensors and cameras is archived here, as documented in the data report.
description: Rolling pendulum (RP) isolation bearings are commonly used in seismic isolation systems for the protection of sensitive building contents. We conducted a study at the Natural Hazards Engineering Research Institute (NHERI) Experimental Facility (EF) at Lehigh University, which involved experimental tests of full-scale RP isolation bearings with different surface treatment thicknesses. The specific goals of the study were to characterize the RP bearings and to assess their performance for use in a floor isolation system (FIS) considering coupling with (i) rigid or flexible equipment mounted on the FIS and (ii) the building in which the FIS is installed. The complete study includes: (1) Characterization tests of the RP isolation bearings; (2) Real-time hybrid simulation (RTHS) tests of the RP isolation bearings incorporating (a) FIS-equipment interactions and (b) building-FIS interactions. This data publication corresponds to the characterization tests. The RTHS tests will be published in the coming months as a hybrid simulation and linked to this publication. All the details regarding the experiment and the data organization and naming are in the Data Report. Additional information on the study, along with details on the data processing and validation, is available in Related Work (Covarrubias Vargas, 2021; Covarrubias Vargas et al., 2022). The experimental data published here can be used by others to validate mathematical models of RP bearings or evaluate computer vision algorithms for displacement measurement.
