Discrete Rigid Block Analysis To Assess Settlement Induced Damage In Unreinforced Masonry Façades, Ryan Ehresman, Nathan Taylor, Bora Pulatsu, Ece Erdogmus

Durham School of Architectural Engineering and Construction: Faculty Publications

In this study, a system of discontinuous rigid blocks is employed to simulate the possible damage mechanisms in unreinforced masonry (URM) façades and load-bearing frame systems subjected to settlement using the discrete element method (DEM). First, the employed modeling strategy is validated utilizing the available experimental results presented in the literature. Once there is a good agreement between the computational models and experimental findings, a sensitivity analysis is performed to quantify the influence of the input parameters defined in the DEM-based numerical model. Finally, the proposed modeling strategy is further utilized to assess the damage pattern that may develop in …

This series began with the mission of questioning practices and education in the built environment that are integrated in formal instruction. The goal is to utilize an alternative method of education where participants (students, faculty, staff, and administrators) recognize how their discipline shapes and supports systems of oppression, while giving them tools to combat it. …

Large-Scale Timber Shear Wall Experimentation In An Undergraduate Design Course, Taylor Christian Cardinale, Michael James Deigert, Anahid Behrouzi, John W. Lawson

Architectural Engineering

Despite the widespread use of light-frame timber construction in residential building, wood design courses are typically offered to graduate students and focus on member-level calculations for gravity and lateral systems per the National Design Specification (NDS) for Wood Construction. In years prior, the 10-week advanced undergraduate class described in this paper exposed students through a system-level perspective through a group design project of a multistory, mixed-use wood building located in a seismic region. A significant course modification in Fall 2020 involved the two class sections constructing and testing large-scale wood shear walls representing a one-story segment of a wall present …

Random Packing Material In Disinfection Contactors: Effects On Baffling And Energy Loss, Jessica L. Baker, Subhas K. Venayagamoorthy, Susan K. De Long

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study investigates the potential improvement in the hydraulic disinfection efficiency and the possible energy loss as a result of the presence of random packing material (RPM) in a laboratory-scale chlorine contactor. Tracer tests were conducted on a 55-gal drum tank filled with RPM in varying amounts in different configurations to measure the efficiency of each setup in terms of baffling factor (BF). The bulk pressure drop was measured to determine the energy loss for each configuration. The results of this study show that securing RPM near the inlet, in any amount, improves the BF by 300% to more than …

Achieving Domestic Internationalization And Global Competence Through On-Campus Activities And Globally Responsive Education, Sanjay Tewari, Peng Zhang, Yuan Zhuang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The impacts of the COVID-19 pandemic on students and educators are well known. However, there is a paucity of literature available on its impact on educational institutions in the context of their abilities to develop global competence in the middle of an ongoing pandemic. The virtual communication and remote delivery of educational content have been a popular trend for many universities to adapt to the pandemic challenges and re-think their internationalization strategies.

The limited travel opportunities because of the pandemic have highlighted a big need for the domestic internationalization mechanism at educational institutions. In this paper, the authors discuss how …

A Comparison Between Ultrasonic Guidedwave Leakage And Half-Cell Potential Methods In Detection Of Corrosion In Reinforced Concrete Decks, Ahmad Shoaib Amiri, Ece Erdogmus, Dana Richter-Egger

Durham School of Architectural Engineering and Construction: Faculty Publications

This article presents the advantages and limitations of a recently developed Ultrasonic Guided Wave Leakage (UGWL) method in comparison to the well-known Half-Cell Potential (HCP) method in their ability to detect corrosion in reinforced concrete (RC) bridge decks. This research also establishes a correlation between UGWL data and chloride content in concrete RC slabs. Concrete slabs submerged in a 10% NaCl solution were monitored using both methods over a period of six months. The chloride content from the three cores (0.84, 0.55, and 0.18%) extracted from the slab after the 6-month long process all exceeded the chloride threshold values suggested …

Early-Age Strength Of Co2 Cured Alkali-Activated Blast Furnace Slag Pastes, Yubin Jun, Seong Ho Han, Jae Hong Kim

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The effect of CO₂ curing including pre-conditioning on alkali-activated slags, activated by different alkaline activators (NaOH, Na₂SiO₃, and KOH solution), is studied. While dry pre-conditioning before the CO₂ curing increases the strengths of all mixtures, the effect of pre-conditioning time is dependent on the alkali activator used to produce samples. The CO₃-bearing reaction product in samples also depends on the alkali activator. Gaylussite, pirssonite, hydrotalcite, and calcite are observed in the NaOH activator, and calcite, hydrotalcite, and C₄AcH₁₁ are detected in the NaOH and Na₂SiO₃ (9:1) …
