Photogrammetry-Based Method For Measuring Volume Changes Of Soil Specimens During Critical Phases Of Triaxial Testing, Sara Fayek, Xiong Zhang, Pingxin Xia
Photogrammetry-Based Method For Measuring Volume Changes Of Soil Specimens During Critical Phases Of Triaxial Testing, Sara Fayek, Xiong Zhang, Pingxin Xia
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Triaxial tests has been routinely used to measure the stress–strain relationship for geomaterials. During triaxial testing, many sources of errors that cannot be completely avoided but are often ignored or approximated using empirical equations. This paper presents a systematic investigation of soil volume change, volume strain nonuniformity, and cross-sectional calculation along the specimen during triaxial testing using a photogrammetry-based method. Consolidated drained triaxial tests were performed in which two parallel measurements were taken: (1) relative volume using the conventional triaxial testing and (2) absolute volume using the photogrammetry-based method. The difference in the observed volume and void ratio measurements between …
Linear Waltz With Nature: A Self-Supporting Infrastructure In Nature, Shangkun Zhong
Linear Waltz With Nature: A Self-Supporting Infrastructure In Nature, Shangkun Zhong
Architecture Senior Theses
This project aims to create a sustainable system that addresses waste management issues in urban areas by examining the functionality of recycling infrastructures and how they can be integrated. The system will absorb waste and convert it into renewable energy to support a field station in Tibet, where self-sustainability is critical, due to the remote location. Architects often demonstrate their understanding of sustainability through various means such as integration, passive/energy-saving, and natural architecture. This thesis argues that a sustainable system such as CopenHill, can exemplify the combination of green-manifested design and recycle content as a sustainable cycle that supports human-nature …
Evaluation Of Thermal And Rheological Properties Of Phase Change Material-Incorporated Asphalt Mastic With Porous Fillers, Farshad Saberi Kerahroudi, Yizhuang David Wang, Jenny Liu
Evaluation Of Thermal And Rheological Properties Of Phase Change Material-Incorporated Asphalt Mastic With Porous Fillers, Farshad Saberi Kerahroudi, Yizhuang David Wang, Jenny Liu
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Incorporating phase change material (PCM) into paving materials can regulate the pavement temperature, improve the pavement durability, and mitigate the heat-island effects. In this research, porous fillers were used as the PCM carrier, and the thermal and rheological behaviors of the asphalt mastic with the PCM were evaluated. Two different carrier materials (diatomite and expanded perlite) and four types of PCMs were used in the study. The candidate filler, PCM, and proper blending ratios were determined based on the results of scanning electron microscope image analysis, the filter paper test, and the temperature sweep test. The thermal and rheological behaviors …
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
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. …
Life Cycle Cost Analysis Of High Friction Surface Treatment Applications, Eslam Deef-Allah, Korrenn Broaddus, Magdy Abdelrahman
Life Cycle Cost Analysis Of High Friction Surface Treatment Applications, Eslam Deef-Allah, Korrenn Broaddus, Magdy Abdelrahman
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Life cycle cost analyses for high friction surface treatment (HFST) applications were executed relying on a Microsoft Excel program developed by the researchers. Calcined bauxite (CB), five CB alternatives, and epoxy binder were utilized in the HFST applications. The aggregates' performances were evaluated through the aggregate image measurement system (AIMS) before and after Micro-Deval polishing. The performance of the HFST applications was evaluated by the dynamic friction tester (DFT) and British pendulum (BP). The major purpose of this program was to present a rational method for converting different input data (project and material specifics) to comparable output data (net present …
Innie/Outie | Renegotiating Figure And Structure, Maxwell Rosner
Innie/Outie | Renegotiating Figure And Structure, Maxwell Rosner
Architecture Senior Theses
This thesis contends that in order to sustain its claim to be socially progressive and accessible enterprise, the discipline of architecture must resist the divorce of figure and structure.
Innie/Outie considers Architecture as a simultaneously typological and teleological proposition. Architects exploit typology as a means of classifying, diagramming, and ultimately flattening and iconicizing ideas about Architecture so as to place them within a broader cultural context, thereby making them intellectually accessible to their audiences. By contrast, architects from the advent of Modernism onwards have displayed a critical preoccupation with the discipline’s teleological potential, the creation of form that follows function …
Two Lands, One System | Redefining The Border Crossing, Matthew Trulli
Two Lands, One System | Redefining The Border Crossing, Matthew Trulli
Architecture Senior Theses
The Israeli and Palestinian populations each have their own distinct infrastructural system, which operates independently and fails to connect the people in this region. This thesis contends that if a two-state solution is implemented under the guidelines of the 2003 Geneva Accord, new connections can stitch the populations of Israel and Palestine together through a reimagined border system.
These divisive infrastructural networks, which are a result of tense relationships, have also sparked increased violence throughout the region, particularly in Jerusalem. The French Hill, located north of the Old City in Jerusalem, is positioned at a critical point in the infrastructural …
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …
