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 ...

Multimodal Transit And A New Civic Architecture, Samuel Bruce Hill 2020 University of Massachusetts Amherst

Multimodal Transit And A New Civic Architecture, Samuel Bruce Hill

Masters Theses

We live in an age defined by the automobile and its infrastructure. This paradigm of movement has shaped how we live our lives, and the urban frameworks we inhabit. Cars as a form of transportation damage the environment and engender unsustainable lifestyles. They also create anti-social spaces with the infrastructure they require, and therefore their success is inverse to that of the pedestrian experience.

I seek to adapt this transit paradigm with a more flexible and resilient multimodal system. My work focuses on reinvigorating a rail line in central Massachusetts and designing a modular station system that can serve as ...


Understanding The Impact Of Room Acoustic Conditions On The Kurtosis Levels Of Various Noise Signals, William Spallino 2020 University of Nebraska - Lincoln

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.

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.

Analysis Of Burning Wood In The Transient State And The Application To Structural Design, Roberta Veliz, Kimberly Guzman 2020 California Polytechnic State University, San Luis Obispo

Analysis Of Burning Wood In The Transient State And The Application To Structural Design, Roberta Veliz, Kimberly Guzman

Architectural Engineering

Determining the extent of the contribution of exposed timber on compartment fire dynamics in open floor plans is a complex process. Designers traditionally used compartmentalization design methods which create spaces where flashover is likely, given the fuel load and ventilation conditions. However, due to the large geometric dimensions and spread of fuel, fires in open floor plans are more likely to remain as localized or traveling fires. As such, an understanding of not only ignition potential but also flame spread is critical to characterizing the contribution of exposed timber. An integral step in characterizing the potential contribution is through an ...
