Assessment Of Small-Scale Anisotropy In Stably Stratified Turbulent Flows Using Direct Numerical Simulations, Amrapalli Garanaik, Subhas Karan Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, the validity of the widely used Kolmogorov hypothesis of local isotropy of dissipative scales in stably stratified turbulent flows is investigated using high-resolution direct numerical simulations. Departure from isotropy is investigated for the first time in terms of the turbulent Froude number defined as Fr = ϵ/(NEk), where N is the buoyancy frequency, Ek is the turbulent kinetic energy, and ϵ is the rate of dissipation of turbulent kinetic energy. It is shown that for both ϵ and the rate of scalar (density) dissipation, ϵρ, the small-scale statistics are nearly isotropic in the weakly stratified turbulent regime …

Clt Shearwall Dovetail Connection, Alexander Eduardo Esser, August Messano

Architectural Engineering

As cross-laminated timber has become an increasingly popular construction material, its use as a shear wall element has also demanded attention. Primary obstructions to the use of CLT shear walls have been the lack of an economic connection type that does not compromise the structural integrity and has the robustness that CLT shear wall panels deserve. Dovetail connections provide a great option for the connection of CLT shear walls. With more experimentation, the optimal dovetail geometry can be further developed. The small-scale testing done in conjunction with this report proved that very deep pins and tails will result in bearing …

Evaluation Of Hospital Soundscapes To Improve Patient And Staff Experience, Jay Bliefnick

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Hospital soundscapes can be difficult environments to assess acoustically due to the continuous activity within units. Routinely, patients perceive these soundscapes poorly when rating their hospital experience on HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) surveys administered after discharge. In addition, hospital staff can be negatively impacted by the acoustical environments in which they work, affecting both performance and job satisfaction. This doctoral research addressed these issues across three phases by collecting acoustical measurements within three individual hospitals, comparing results with provided patient and staff survey information, and conducting laboratory tests of hospital noise perception. In the first …

The Evaluation Of Current Wall-To-Roof Anchorage Force Provisions For Single-Story Concrete And Masonry Buildings With Lightweight Flexible Diaphragms, John Lawson, Maria Koliou, Andre Filiatrault, Dominic Kelly

Architectural Engineering

Along the seismically active west coast of the United States (US), heavy concrete and masonry walled buildings with lightweight wood or steel flexible roof diaphragms are commonplace and have grown in size over the years. The current force levels found in ASCE’s Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE 7-16) for designing the out-of-plane wall anchorage system in these buildings is the result from a series of California earthquakes, causing a series of structural failures and subsequently revisions to the Uniform Building Code (UBC). This trial-and-error approach is the basis for current wall anchorage code …

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.

Architectural Engineering

ABET has revised the criteria 3 (Student Outcomes) and 5 (Curriculum) of the general criteria. These changes have made it through the rigorous approval process and will be effective for the 2019-20 academic year. This paper analyzes the differences between the existing criteria and the proposed changes. Through a specific detailed example, the paper illustrates how an existing assessment system can seamlessly be adjusted for the new criteria. Most of the embedded indicators and direct measures of attainment can still be used. The results simply need to be organized differently.

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 …

Seismic Performance Of Slender C-Shaped Walls Subjected To Unii- And Bi-Directional Loading, Anahid A. Behrouzi, A. Mock, D. Lehman, L. Lowes, D. Kuchma

Architectural Engineering

Reinforced concrete structural walls are common as the primary lateral load resisting system in modern mid- and high-rise buildings constructed in seismic regions, yet few research programs have investigated the seismic performance of modern, slender walls with nonplanar cross-sectional geometries. Three large-scale, C-shaped wall specimens, designed per ACI 318-08, were tested under uni- and bi-directional loading at the University of Illinois at Urbana-Champaign (UIUC). This paper presents experimental results including the cyclic load-deformation response and measured versus nominal flexural/shear strengths as well as a description of damage sequence. Final failure occurs due to a flexure-tension failure of boundary elements where …

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, …
