A Framework For Estimating Immediate Interdependent Functionality Reduction Of A Steel Hospital Following A Seismic Event, Emad M. Hassan, Hussam Mahmoud

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Functionality of an infrastructure is its ability to provide its intended services. Maintaining an acceptable level of infrastructure functionality, particularly for critical infrastructure, following an extreme event is vital for effective community recovery. Estimating functionality depends on proper quantification of losses, which requires accurate assessment of infrastructure damage. The damage is presented in the form of fragility functions that are generally developed using nonlinear finite element analysis. To date, no study has been conducted to assess the effect of modeling approach on seismic fragilities of an infrastructure, the associated losses, and functionality reduction. In addition, existing frameworks for estimating functionality …

Revisiting Earthquake Lessons: Wall Anchorage To Flexible Diaphragms, John W. Lawson

Architectural Engineering

In the 1971 San Fernando earthquake, large numbers of concrete tilt-up warehouse buildings had partial roof collapses as perimeter walls separated from the roof. The culprit was a design flaw that relied upon wood ledgers in cross-grain tension/bending for anchorage of the wall to the roof diaphragm. In the 1984 Morgan Hill and 1989 Loma Prieta earthquakes, instrumented tilt-up buildings indicated that past code-level anchorage forces were too low; and in the 1994 Northridge earthquake it was observed that anchorage systems had insufficient ductility and overstrength to resist the high force demands.

Molecular Dynamics Simulation Study On The Possible Factors Affecting Stability Of Ods Steel, M. Mustafa Azeem, Zhongyu Li, Qingyu Wang, Abid Hussian

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Oxide-dispersed-strengthened (ODS) steel has excellent mechanical, thermodynamic and radiation resistant properties, which makes it an important candidate material for high-Temperature reactors applications. Radiation stability of oxide is very important to study at the atomic level. In present case molecular dynamics (MD) simulation is used to study stabilities of Y₂O₃ particles in ODS steel as a function of particle sizes. The size dependence is obvious for particle sizes larger than 2.8 nm. Furthermore, the stabilities depend on charges of Y and O atoms.

Deep Learning For Automated Image Classification Of Seismic Damage To Built Infrastructure, B. Patterson, G. Leone, Maria Pantoja, Anahid A. Behrouzi

Architectural Engineering

The amount of structural damage image data produced in the aftermath of an earthquake can be staggering. It is challenging for a few human volunteers to efficiently filter and tag these images with meaningful damage information. The proposed solution is to automate post-earthquake reconnaissance image tagging activities by training a computer algorithm to classify each occurrence of damage per building material and structural member type. The approach is based on deep learning (DL), a subset of machine learning loosely based on the operation of a biologic neural system, which aims to learn and extract accurate representations from large data sets. …

Photo Tagging Tool For Rapid And Detailed Post-Earthquake Structural Damage Identification, Anahid A. Behrouzi, Maria Pantoja

Architectural Engineering

A significant task in earthquake reconnaissance is to conduct rapid and accurate assessments of damage to built infrastructure. This can be accomplished, in part, by analyzing the large volumes of high-resolution image data collected after a seismic event. However, detailed image tagging remains a task for trained human volunteers, which is both time-intensive and error prone. The authors developed a software tool to simplify and standardize the process of assigning damage and structure pairs to sub-regions of images. The goal of the tool is to facilitate the tagging of thousands of images from historic and recent earthquakes to train a …

Software Toolset To Enable Image Classification Of Earthquake Damage To Above-Ground Infrastructure, Anahid A. Behrouzi, Maria Pantoja

Architectural Engineering

A critical task after a significant earthquake is determining the extent of damage to infrastructure networks. The decision-making process to dispatch emergency, repair, and in-field reconnaissance teams depends on whether road/railways and bridges are passible. Another concern is the rapid identification and resolution of physical disruptions to large-volume gas and water pipeline systems. After large seismic events, citizens, amateur photographers, and journalists now post thousands of photographs to formal/social media platforms. In the past, these images would have had to be reviewed by trained volunteers or expert engineers to evaluate whether: road/rail ways were significantly impacted by ground fracture, heaving, …
