A Comparison Between Ultrasonic Guided Wave Leakage And Half-Cell Potential Methods In Detection Of Corrosion In Reinforced Concrete Structures, Ahmad Shoaib Amiri Aug 2020

A Comparison Between Ultrasonic Guided Wave Leakage And Half-Cell Potential Methods In Detection Of Corrosion In Reinforced Concrete Structures, Ahmad Shoaib Amiri

Architectural Engineering -- Dissertations and Student Research

Corrosion of reinforcing steel bars (rebar) in reinforced concrete decks can lead to serious structural issues in bridges. Ultrasonic Testing (UT) methods provide small wavelengths that can be used for early detection of several types of deterioration. The recently-developed Ultrasonic Guided Wave Leakage (UGWL) Method utilizes steel as the waveguide and measures the energy leaked into the surrounding concrete. Previous studies completed at University of Nebraska-Lincoln demonstrated that the measurements of the leaked energy using receivers from the concrete surface can successfully identify early stages of various flaws such as corrosion, delamination, and cracking. In this method, the longitudinal waves ...

Understanding The Impact Of Room Acoustic Conditions On The Kurtosis Levels Of Various Noise Signals, William Spallino Jul 2020

Understanding The Impact Of Room Acoustic Conditions On The Kurtosis Levels Of Various Noise Signals, William Spallino

Architectural Engineering -- Dissertations and Student Research

Impulsive noise can be common in certain occupational and recreational settings, such as manufacturing plants, construction sites, and firing ranges. While many regulations and guidelines for noise exposure exist, their mathematical basis is stronger for continuous noise, and concerns have been raised about the possibility that impulsive noise may be more harmful to people’s hearing than those metrics would let on. Much work has been done on establishing metrics that accurately assess the severity and hearing risk associated with impulsive noise, but the effects of room acoustic conditions on those metrics have been heretofore understudied.

This study calculated room ...

Implementing Bluebeam Software In Architectural Engineering Design Courses, Michael James Deigert, Anahid A. Behrouzi, Pamalee A. Brady

Architectural Engineering

A critical aspect of structural engineering education is helping students develop effective electronic graphical communication skills to convey their design solutions. Many undergraduate civil and architectural engineering programs address this at the document creation stage by teaching Autodesk AutoCAD or Revit to create 2-D or 3-D structural design files. However, students tend to have limited exposure to commercial software for document management and markup that allows for coordination between the engineer, architect, and contractor teams. Bluebeam Revu is one such software that has emerged as an industry standard for annotation and markup of engineering design documents.

Evaluation Of The Dynamic Behavior Of Steel Staircases With Concrete Filled Pan Treads, Tyler Sondag May 2020

Evaluation Of The Dynamic Behavior Of Steel Staircases With Concrete Filled Pan Treads, Tyler Sondag

Architectural Engineering -- Dissertations and Student Research

Vibration serviceability of staircases has been a growing challenge for structural engineers due to changing materials and structural forms. In order to prevent or correct serviceability problems due to structural vibrations, structural engineers should be able to predict the dynamic performance of a staircase structure. However, there are few technical guides available for designing steel staircases, and the ones that do exist are often limited in their applications. Currently, there is a lack of research on staircases that are less prone to vibrations, such as staircases with concrete filled pans that are composed of face and wall stringers. Therefore, the ...

Attracting and developing the next-generation workforce is not without its challenges; however, students are often deficient in technical skills and generally have negative perceptions about manufacturing and construction. As a result, new education and training models have been developed to provide instruction at all levels of the educational system, with a focus on both traditional students and non-traditional students, including ethnic minorities, women ...


Investigating Multidimensional Characteristics Of Noise Signals With Tones From Building Mechanical Systems And Their Effects On Annoyance, Joonhee Lee, Lily M. Wang Jan 2020

Investigating Multidimensional Characteristics Of Noise Signals With Tones From Building Mechanical Systems And Their Effects On Annoyance, Joonhee Lee, Lily M. Wang

Architectural Engineering -- Faculty Publications

This paper investigates multidimensional characteristics of tonal noise from heating, ventilation, and air-conditioning systems, besides loudness and tonality, to improve prediction of annoyance. Two studies were conducted: multidimensional scaling (MDS) analysis to determine what other perceptual signal characteristics are important and perceptual weight analysis (PWA) to understand the impact of multiple tones in a signal. In the MDS study, paired comparison tasks were conducted to gather similarity and annoyance data. Results show that the latent perceptual dimensions are related to the signal’s tonality, loudness, sharpness, and roughness. Including metrics for these perceptions, except roughness, improves the performance of earlier ...

An Investigation Into Current Procurement Strategies That Promote Collaboration Through Early Contractor Involvement With Regards To Their Suitability For Irish Public Work Projects, Barry Mcauley, Frederic Lefebvre

Conference papers

Previous research has established that multi-disciplinary collaboration will benefit a construction project throughout its lifecycle. While Lean Construction, Building Information Modelling (BIM), and Integrated Project Delivery (IPD) can all be viewed as separate processes which add independent value to a project, they are more effective when used in partnership with each other. In order to ensure the high levels of collaboration expected for these processes to work in unison, the early involvement of the Contractor is paramount. Early contractor involvement within the design process can ensure a more focused integrated project team, improvement of both constructability and cost certainty, as ...

Conference papers

The construction industry consumes up to 50% of mineral resources excavated from nature, generates about 33% of CO2 present in the atmosphere and is responsible for 40% of total global energy through both construction and operation of buildings. The realisation that current pervasive construction practices now face globalization, sustainability, and environmental concerns, as well as ever-changing legislation requirements and new skills needed for the information age has resulted in technologies such as Building Information Modelling (BIM) becoming a key enabler in navigating these barriers. To assist in overcoming these barriers, a number of funding initiatives have been put in place ...


Bim In Ireland 2019: A Study Of Bim Maturity And Diffusion In Ireland, Barry Mcauley, Alan Hore, Roger West Sep 2019

Bim In Ireland 2019: A Study Of Bim Maturity And Diffusion In Ireland, Barry Mcauley, Alan Hore, Roger West

Conference papers

In 2017, the BIM Innovation Capability Programme team applied five macro BIM maturity conceptual models to capture the capability of the Irish construction industry and assess its BIM maturity. The results found that while Ireland is mature for modelling processes, it is less developed with regards to collaboration processes and policies. Ireland also ranked poorly when it came to regulatory frameworks, measurements and benchmarks compared to a number of countries which also applied the same conceptual models. At the time, the findings highlighted that Ireland’s diffusion dynamic was middle out, meaning that larger organisations or industry associations were pushing ...

The WEF report highlighted actions that companies, industry organisations and governments are advised to implement to accelerate BIM adoption and better capitalise on delivering better project outcomes. According the authors of the report BIM is seen as the centrepiece of the construction industry’s digital transformation, however they acknowledged that BIM adoption globally remain slow. Anecdotal experience would suggest that BIM usage in Ireland is also very low and that a similar initiative or an adaptation ...


Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang Sep 2019

Quantification Of Heat Flows Through Building Entrance Doors On A Winter Day, Daeho Kang

Publications and Research

The current methods for the prediction of the heat flow through building entrance doors have been used for years while involved with a certain degree of uncertainty. This paper describes an experimental method that accurately quantified such heat flow. The experiment monitored local environmental parameters in a college building on a cold winter day. The results of the experiment demonstrated that the experimental method is viable to accurately estimate the heat flow throughout the entrance doors and the presence of a vestibule moderated heat losses from the conditioned area. The results will be used for validating the existing methods.

This study is intended to evaluate the capability of a spray PDEC system for space cooling. It comprises four simulation scenarios to see the system response and influence of indoor thermal environment when a spray PDEC system is adopted as a primary cooling system in two different climates. The simulation results show that a spray PDEC system causes a substantial variation in the indoor thermal environment ...


Feasibility Of A Fiber Reinforced Polymer Retrofit For Non-Ductile Concrete Walls, Rory S. De Sevilla, Jerry Hue Truong Luong, Anahid A. Behrouzi, Peter T. Laursen, Mike J. Deigert Aug 2019

Feasibility Of A Fiber Reinforced Polymer Retrofit For Non-Ductile Concrete Walls, Rory S. De Sevilla, Jerry Hue Truong Luong, Anahid A. Behrouzi, Peter T. Laursen, Mike J. Deigert

Architectural Engineering

A significant number of pre-1980’s non-ductile reinforced concrete (RC) structures in California have been identified as deficient, many of which utilize RC shear wall systems to resist earthquake lateral forces. These non-ductile wall systems are typically lightly reinforced and lack adequate boundary element detailing. Engineers suspect these walls to susceptible to brittle, compression-controlled failure modes due to damage from concrete crushing and bar buckling. As a result, one approach designers are taking is to seek fiber reinforced polymer (FRP) retrofit solutions that improve the compression capacity of high-stressed wall end zone regions based on effectiveness of these approaches with ...
