The Influence Of National Culture On Effectiveness Of Safety Trainings During Postdisaster Reconstruction, Behzad Esmaeili, Kevin Grosskopf, Amy Javernick-Will Jan 2014

The Influence Of National Culture On Effectiveness Of Safety Trainings During Postdisaster Reconstruction, Behzad Esmaeili, Kevin Grosskopf, Amy Javernick-Will

Durham School of Architectural Engineering and Construction: Faculty Publications

Non-English speaking workers constitute a disproportionately high number of workers involved in postdisaster reconstruction. Additionally, the rate of fatality among these workers is higher than the industry average. Research shows this population is more prone to unsafe behaviors in the working environment, conceivably because many of these workers are sent into the field prior to any formalized training. Recent studies show that the native culture of construction workers can impact risk-taking behavior. While numerous researchers have attempted to develop training materials for Hispanic workers, the number of studies that consider the impact of native culture on safety behavior is minimal. …

Shallow Flat Soffit Precast Concrete Floor System, George Morcous, Maher Tadros Jan 2014

Shallow Flat Soffit Precast Concrete Floor System, George Morcous, Maher Tadros

Durham School of Architectural Engineering and Construction: Faculty Publications

A precast concrete floor system that eliminates the need for column corbels and beam ledges while being very shallow. The main advantages of the present system include a span to-depth ratio of 30, a flat soffit, economy, consistency with prevailing erection techniques, and fire and corrosion protection. The present system consists of continuous precast columns, prestressed rectangular beams, hollow-core planks, and cast-in-place composite topping. Testing results have indicated that a 12 inch deep flat soffit precast floor system has adequate capacity to carry gravity loads (including 100 psf live load) in a 30 ft x 30 ft bay size. Testing …

Thermophysical And Mechanical Properties Of Hardened Cement Paste With Microencapsulated Phase Change Materials For Energy Storage, Hongzhi Cui, Wenyu Liao, Shazim Ali Memon, Biqin Dong, Waiching Tang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this research, structural-functional integrated cement-based materials were prepared by employing cement paste and a microencapsulated phase change material (MPCM) manufactured using urea-formaldehyde resin as the shell and paraffin as the core material. The encapsulation ratio of the MPCM could reach up to 91.21 wt%. Thermal energy storage cement pastes (TESCPs) incorporated with different MPCM contents (5%, 10%, 15%, 20% and 25% by weight of cement) were developed, and their thermal and mechanical properties were studied. The results showed that the total energy storage capacity of the hardened cement specimens with MPCM increased by up to 3.9-times compared with that …

Civic Deliberative Dialogue And The Topic Of Race: Exploring The Lived Experience Of Everyday Citizens And Their Encounters With Tension And Conflict, Jacquelyn Yvonne Mccray Jan 2014

Civic Deliberative Dialogue And The Topic Of Race: Exploring The Lived Experience Of Everyday Citizens And Their Encounters With Tension And Conflict, Jacquelyn Yvonne Mccray

Antioch University Full-Text Dissertations & Theses

The research explored the interactions and experiences of participants and facilitators in civic deliberative dialogue and how they worked through tension and conflict. The dissertation question asked: What is the lived experience of participants and facilitators of civic deliberative dialogue and how do group members collectively move beyond tensions and disagreements that surface during dialogue processes? The study analyzed the joint influences of tension and disagreement within the context of seven deliberative dialogues convened on the topics of race, race relations and racism. Grounded theory methodology was used to analyze qualitative research data collected from participant volunteers and facilitators. A …

Evaluating The Benefits Of And Barriers To Building With Structural Insulated Panels, Alison E. Moynihan Jan 2014

Evaluating The Benefits Of And Barriers To Building With Structural Insulated Panels, Alison E. Moynihan

Student Showcase

Changing climate and increasing costs of energy are putting pressure on the building industry to adapt to higher performance building systems. One technology that can improve building performance is structural insulated panel (SIP) construction. The purpose of my practicum is to evaluate the possible benefits of SIPs and to identify obstacles to SIPs gaining a larger portion of the building industry. Using the information from practicum I intend to evaluate current design tools and suggest my own tools. The benefits of SIPs are lower thermal bridging and air infiltration leading to lower operating costs and minimal material usage. Findings include …

Stock Aggregation Model And Virtual Archetype For Large Scale Retrofit Modelling Of Local Authority Housing In Ireland, James Pittam, Paul D. O’Sullivan, Garrett O’Sullivan Jan 2014

Stock Aggregation Model And Virtual Archetype For Large Scale Retrofit Modelling Of Local Authority Housing In Ireland, James Pittam, Paul D. O’Sullivan, Garrett O’Sullivan

Conference Papers

Developing representative archetypes using a bottom up approach for stock modelling is an excellent tool for evaluating the overall performance of the building stock; however it requires detailed analysis of the various building types. Currently there is no detailed housing data base for Local Authority housing in Cork City, Ireland that catalogues the housing stocks geometric properties and thermal characteristics for each typology. This study details a methodology to catalogue the LAH stock and build a detailed housing data base. The GIS web based mapping application Google Street View is used to identify 20 house typologies across 36 LAH developments; …

Behavior Of I-Section Gfrp Beam Including Retrofitting For Damage Effects, Mamadou Konate, Zia Razzaq Jan 2014

Behavior Of I-Section Gfrp Beam Including Retrofitting For Damage Effects, Mamadou Konate, Zia Razzaq

Civil & Environmental Engineering Faculty Publications

This paper presents the outcome of a study of an I-section Glass Fiber Reinforced Polymer (GFRP) beam including retrofitting for damage effects. A total of three beam tests were conducted in the following sequence: GFRP beam with no retrofitting and a single mid-span web brace; the partially damaged (cracked) beam with GFRP plates used for retrofitting; and the retrofitted beam re-tested with the lateral brace at the top flange level. Both cracking and lateral-torsional buckling behavior is studied and experimental load-deflection relationships recorded. Using the mechanical properties of GFRP based on the experimental data, theoretical predictions are made for the …

Preserving The Historic Garden Suburb: Case Studies From London And New York, Jeffrey A. Kroessler Jan 2014

Preserving The Historic Garden Suburb: Case Studies From London And New York, Jeffrey A. Kroessler

Publications and Research

The garden city or garden suburb was a response to the social and environmental ills of cities at the turn of the twentieth century. Letchworth Garden City, Hampstead Garden Suburb, and Welwyn Garden City were built outside London in the early 1900s, and each remains a highly desirable place of residence today. From the start, each was tightly regulated, and remains so a century later. By protecting the appearance and enhancing property values, the strict application of historic preservation principles contribute to the long-term sustainability of each place. Similar garden suburbs were built in the borough of Queens in New …

Inclusionary Eminent Domain, Gerald S. Dickinson Jan 2014

Inclusionary Eminent Domain, Gerald S. Dickinson

Articles

This Article proposes a paradigm shift in takings law, namely “inclusionary eminent domain.” This new normative concept provides a framework that molds eminent domain takings and economic redevelopment into an inclusionary land assembly model equipped with multiple tools to help guide municipalities, private developers and communities construct or preserve affordable housing developments. The tools to achieve this include Community Benefit Agreements (“CBAs”), Land Assembly Districts (“LADs”), Community Development Corporations (“CDCs”), Land Banks (“LABs”), Community Land Trusts (“CLTs”) and Neighborhood Improvement Districts (“NIDs”). The origin of the concept derives from the zoning law context, where exclusionary zoning in the suburbs excluded …
