Shear Behavior Of Reinforced Concrete Shallow Beams With Lightweight Infill, Ahmed Mohamed Tahwia, Mohamed El Saied El-Zoughiby, Mohammed Hany Hassan

Mansoura Engineering Journal

This paper presents the effect on the shear behavior of reinforced concrete shallow beams due to infilling by using the Autoclaved Aerated Concrete (AAC) as a lightweight material to decrease the weight of the beams. Three reinforced concrete beams were fabricated in the lab to study the effect of infilling the beams with AAC blocks. The first beam is a solid or reference beam, SB01. The second beam was in filled by four AAC blocks having 100mm thick ribs, SB02. The last beam was also in filled but with eight AAC blocks having 40mm thick ribs, SB03. Based on the …

Homogenous Flow Performance Of Steel Fiber-Reinforced Self-Consolidating Concrete For Repair Applications: Developing A New Empirical Set-Up, Naimeh Nouri, Masoud Hosseinpoor, Ammar Yahia, Kamal Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, a new empirical Square-Box test was employed to evaluate the homogeneous flow performance of fiber-reinforced self-consolidating concrete (FR-SCC) under confined-flow conditions that are typical of repair applications. The Square-Box set-up consisted of a closed-circuit box, providing 2.4-m flow distance and a closed-surface cross section of 100-mm width and 200-mm height, equipped with 0 and 4 rows of reinforcing bar grids with 45-mm clear spacing. The flow performance was assessed in terms of dynamic stability and passing ability. The investigated mixtures were considered as diphasic suspensions of fiber-coarse aggregate (F-A > 5 mm) in suspending mortars containing particles finer …

Nashville Trail Of Tears Museum, Emily Schiedemeyer

[Archive] Belmont University Research Symposium (BURS)

Architecture is the manifestation of artistic expression which can serve as both a storytelling device and a mechanism to evoke an intentional emotional reaction of its occupants. The Nashville Trail of Tears Memorial is intended to reflect the story of the Cherokee nation and give visitors the opportunity to consider the horrific journeys taken. The Trail of Tears was the route taken by many Native Americans following the forced displacement and ethnic cleansing of their lands, leaving many dead and families separated. Native to the southern part of the Appalachian chain, the Cherokee tribe is the group of people that …

The Museum As Object Of Display: Experiencing The Ashmolean, Jack Z. Chen

Armstrong Undergraduate Journal of History

Conventionally, museums are most often considered as a series of objects displayed, but I argue that the museum itself should be seen, first and foremost, as the object on display. The Ashmolean Museum in Oxford, built at the high tide of British Imperialism, is a very interesting case study. Interested in its engagement with its own past, I do not seek to investigate the actions it takes as an institution, for instance, as regards to the politics of repatriation. Instead, I want to explore the whole experience it facilitates as an object in its own right.

This experience begins with …

Synergistic Effect Of Shrinkage Mitigating Materials On Rheological Properties Of Flowable And Thixotropic Cement Paste, Kamran Aghaee, Ricarda Sposito, Kamal Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study investigates the effect of individual and combined additions of CaO-based expansive agent (EA), shrinkage reducing admixture (SRA), and super absorbent polymer (SAP) on key characteristics of flowable cement paste mixtures proportioned with a water-to-cement ratio of 0.40. Of special interest is the effectiveness of these admixtures to mitigate shrinkage of cementitious materials for 3D printing. Static and dynamic yield stress, plastic and apparent viscosities, and thixotropy were evaluated at 20-min intervals up to 90 min. Compressive strength development and autogenous shrinkage were also determined. A factorial design approach was developed to evaluate the synergetic effects of the shrinkage …

Spiral Deployment Of Optical Fiber Sensors For Distributed Strain Measurement In Seven-Wire Twisted Steel Cables, Post-Tensioned Against Precast Concrete Bars, Yanping Zhu, Genda Chen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

On-time monitoring and condition assessments of steel cables provide mission-critical data for informed decision making, ensuring the structural safety of post-tensioned concrete structures. This study aimed to develop a spiral deployment scheme of distributed fiber optic sensors (DFOS) and to monitor/assess the post-tensioned force in seven-wire twisted steel cables, based on the pulse-pre-pump Brillouin optical time domain analysis. Each DFOS was placed in a spiral shape between two surface wires of a steel cable and glued to the steel cable by epoxy. Image observations were conducted to investigate the entireness and bonding condition between the optical fiber and the steel …

The Future Of Architecture: Measuring The Sustainability Of Paradigm Shifting Architectural Interventions, Jake M. Cohen

Independent Study Project (ISP) Collection

Sustainable development in the built environment seems paradoxical given that the architecture, construction, and buildings sector is one of most polluting, wasteful, and inefficient industries. Despite this notion, the role of the architect is evolving and their influence on design is expanding beyond ideas for physical structures and into designing interactions between the built environment and components such as policy, material usage, sustainability, and urban regeneration. Architects that are able to implement paradigm shifting design ideas that improve the environmental, social, and economic dimensions of sustainability can be catalytic for systemic change and act as a vehicle to move away …

How Spirituality Intensifies Sustainability: A Case Study Of Ananda Valley In Northern Portugal, Mia Handler

Independent Study Project (ISP) Collection

The religious affiliations of citizens in the West are currently shifting away from the fundamentalist, traditional structures of the past towards more alternative spiritualities. Furthermore, as a result of the climate crisis, ecovillages are becoming increasingly popular. Ecovillages are intentional, “sustainable” communities that seek to reduce consumption, live in harmony with nature, and create strong social bonds. They are characterized by varying levels of spiritual involvement (Greenberg, 2014, p. 274). As such, the objective of this paper is to study the relationship between spirituality and environmentally-friendly practices and attitudes, using the ecovillage Ananda Valley – an Ananda Marga Master Unit …

Characterizing And Modeling The Coupled Hydro-Mechanical Cyclic Behavior Of Unsaturated Soils Using Constant Water Content Oedometer And Direct Shear Tests, Beshoy Riad, Xiong Zhang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Most transportation infrastructures are constructed on compacted soils that are typically unsaturated above the groundwater table. The soils are subjected to cyclic traffic loadings and seasonal wetting–drying cycles. Although problems associated with unsaturated soils are ubiquitous in the US, coupled hydro-mechanical analysis is rarely included in the design/analysis of transportation geosystems. This can be attributed to two main reasons: (a) there are no simple devices/methods which can be used to rapidly characterize stress–strain behavior for unsaturated soils, and (b) there is a lack of a constitutive model to study coupled hydro-mechanical cyclic behavior for unsaturated soils in a consistent way. …

Benefits And Drawbacks Of Using Multiple Shrinkage Mitigating Strategies On Performance Of Fiber-Reinforced Mortar, Kamran Aghaee, Kamal Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Shrinkage mitigating strategies have been successfully used to prevent concrete cracking. Numerous studies have demonstrated the efficiency of shrinkage mitigating materials (SMM), such as expansive agent (EA), shrinkage reducing admixture (SRA), and superabsorbent polymer (SAP) on reducing shrinkage and cracking; however, few studies have addressed the limitations of using these materials. In addition, the mechanism of negative effect on microstructure and mechanical properties when these materials are used at high contents or in combinations is not well defined. This study investigates the effect of CaO-based EA, SRA, and SAP on compressive strength development, fiber pull-out strength, and shrinkage of fiber-reinforced …

A Novel Iron Phosphate Cement Derived From Copper Smelting Slag And Its Early Age Hydration Mechanism, Yunlong Luo, Xintao Zhou, Zhongqiu Luo, Hongyan Ma, Yu Wei, Qin Liu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Copper slag (CS), a by-product of copper smelting, is normally stockpiled, leading to wastes of resource and space as well as environment pollution. It has not been massively reutilized as a supplementary cementitious material in Portland cement due to its low reactivity. In the present study, CS is for the first time utilized as the base component to prepare an iron phosphate cement (IPC) by reacting with ammonium dihydrogen phosphate (ADP) at room temperature. The influence of the raw materials mass ratio (CS/ADP) on the microstructure and performance of IPC pastes are investigated. It is found that the compressive strength …
