Millions of tones of plastic waste are generated globally and only less than 10 per cent has been recycled. It is crucial to segregate and circulate plastic waste and repurposing it for countless other uses. There are many ways to repurpose and reuse these discarded plastics. One use that can be examined is the use of plastic as partial sand replacement in mortar. To contribute to this important and valid discourse, the research studies the mechanical and thermal properties of recycled HDPE mortar as an active way of integrating plastic waste into the construction industry to partially eliminate some of …

Over the last decades, plastic waste (PW) has increased exponentially and has become a serious threat to our planet, aquatic system and human health. Recycling or reusing PW in producing ecofriendly materials is an efficient solution to reduce plastic pollution and to minimize the depletion of raw materials as well. Previous studies have shown promising potentials of using PW in the construction sector, such as binder, aggregate, or substitute of cement and sand in concrete, brick or mortar. Laboratory results indicate that implementing plastic waste as aggregates in cement composites obtains higher thermal resistance and acoustical performance. However, a reduction …
How Can Visual Programing Be Used To Aid The Development Of A Structural Scheme Design Process Utilising Geometric Data Within An Architectural Revit Model?, Ed Carthy, Kieran Lakhera O'Shea
How Can Visual Programing Be Used To Aid The Development Of A Structural Scheme Design Process Utilising Geometric Data Within An Architectural Revit Model?, Ed Carthy, Kieran Lakhera O'Shea

The early-stage structural scheme design of a building is a complex task requiring the collection of multiple information categories such as geometry, loading and materials. The collection and review of this information is traditionally conducted in a 2D environment. This is inefficient, time-consuming, and tedious. This paper provides a review of how structural engineers’ understanding and implementation of BIM has evolved significantly in recent years, validated by extant literature in areas such as BIM automation, visual programming, and structural optimisation in the structural engineering sector. Structural engineers are growing more aware that BIM provides a vast repository of data to …

This course will examine modern public policymaking in the United States. We will examine the different forms that policy can take and how each branch of government can leave a lasting impact on policy. The course will investigate the environment in which policy in the U.S. is shaped and the key official and unofficial actors involved. The course will investigate how public policy issues are defined and earn a place on the policy agenda. The remainder of the course will focus on various criteria for evaluating policy: effectiveness, efficiency, equity, liberty, security, and resilience. The manner in which policy often …

A theoretical study of Glass Fiber Reinforced Polymer (GFRP) beams subjected to biaxial bending moments is presented with a focus on the influence of higher-order effects on maximum normal stresses. It is shown that the biaxial bending type of loading causes a dramatic increase in the maximum normal stress for a GFRP beam when induced torsional effects are included. The study demonstrates that the traditional first-order theory can grossly underestimate the maximum normal stress in a GFRP beam. Based on the numerical results presented using a higher-order theory which also accounts for induced warping normal stresses, the maximum normal stress …

2022 Fall Reports (Marshall, IL)
This class is designed to provide a basic working understanding of statistical methods which are commonly used in the social sciences, including public administration. Students will learn the mathematical logic behind the procedures by calculating statistical formulas. Students will also gain proficiency in completing statistical procedures using Microsoft Excel (the Statistical Package for the Social Sciences, or SPSS, may also be used).
Dissipated Hysteretic Energy Reconstruction For High-Resolution Seismic Monitoring Of Instrumented Buildings, Milad Roochi, Eric M. Hernández, David V. Rosowsky
Dissipated Hysteretic Energy Reconstruction For High-Resolution Seismic Monitoring Of Instrumented Buildings, Milad Roochi, Eric M. Hernández, David V. Rosowsky
Durham School of Architectural Engineering and Construction: Faculty Publications
This paper proposes a high-resolution seismic monitoring framework that employs dissipated energy as a feature for damage detection and localization in instrumented building structures. The the methodology consists of (1) implementing a nonlinear state observer to reconstruct the dynamic response at all degrees of freedom (DoF) of a structural model, (2) employing the reconstructed response to estimate element-by-element forces and displacements, and (3) using estimated displacement, forces, and constitutive laws to estimate elementlevel dissipated energy. The main advantages of the proposed energy-based approach are that i) the proposed feature is physically meaningful and correlates well with the level of cyclic …

Durham School of Architectural Engineering and Construction: Faculty Publications
This paper aims to integrate life-cycle analysis into civil infrastructure resilience modeling and decision-making in seismic-prone communities. To achieve this aim, the authors present a methodology for modeling seismic life-cycle resilience of interdependent buildings and lifeline systems and subsequently informing resilience decisions directly related to the maintenance and retrofit of interdependent infrastructure to enhance a community’s physical, social, and economic systems. The methodology consists of 1) community data collection, 2) seismic hazard analysis, 3) physical damage analysis, and 4) system-level functionality and restoration analysis, 5) socio-economic impact analysis, 6) life-cycle optimization and retrofit decisionmaking. The methodology begins by developing geospatial …
An Updated Analytical Method For Predicting The Bracing Behavior Of Z-Purlin Supported Standing Seam Diaphragm Systems, Michael W. Seek
An Updated Analytical Method For Predicting The Bracing Behavior Of Z-Purlin Supported Standing Seam Diaphragm Systems, Michael W. Seek
Engineering Technology Faculty Publications
Roof systems utilizing Z-purlins as a secondary member supporting a standing seam panel system are used extensively by the metal building industry. The Z-purlins rely on the diaphragm action in the standing seam panel system to provide lateral support and transfer forces to anchorages. The behavior of the standing seam system is highly nonlinear making prediction of the interaction between the Z-purlin and the standing seam system difficult. To better understand the behavior of the interaction between the purlins and the panel system, a series of non-linear shell finite element models were developed based on the test results of simple …
