In this study, the full seismic functionality and recovery process of a six-story hospital, located in Memphis, TN, is quantified and assessed using a comprehensive 3-D finite element …

Investigation Of Grout - A Comparison Of Standard Grout Mix To Self-Consolidating Grout Mix, Rachel Garcia Chandler

Architectural Engineering

Masonry is a major structural material for low rise buildings, however the design of masonry buildings is rarely taught as a formal course at most universities. As part of the educational experience and to become familiar with the specifications and testing procedures for grouted masonry, a student run experiment on varying the water to cement ratio of masonry grout was conducted. The purpose is to report on the effects of changing the water-to-cement (W/C) ratios in a standard grout mix. The typical W/C ratio is approximately 0.80:1.00. In order to show the effects of increasing water in a grout mix, …

Topology And Form Finding Via Genetic Algorithms, Michael Goldenberg, Nick Coburn

Architectural Engineering

The following presents an approach to early applications of the Galapagos program as a means to optimize structural forms. The process was conducted with Rhino’s Grasshopper program, the structural analysis plug-in, Karamba, and the genetic algorithm solver, Galapagos. This topological form finding process was based on flexible parameters that modified brace and column locations, and diaphragm size and positions.

This process worked by having Galapagos modify a parametric model which had initial randomly generated variables for the genomes. After structural analysis, Galapagos was tasked with changing the form in order to minimize overall displacement of the structure. Being an evolutionary …

Axial Testing Of Makeshift Buckling Restrained Braces, Daniel T. Item, Corey Huang

Architectural Engineering

The testing of lateral force resisting systems is a concept that is very open to discussion and optimization. We seek to find the bounds of different materials as they act in a buckling restrained brace system in hopes of providing new methods of design for future structural engineering communities. By balancing budget, customization, and material availability we are able to determine what factors may benefit, or lack to benefit, the system at hand.

On The Inference Of The State Of Turbulence And Mixing Efficiency In Stably Stratified Flows, Amrapalli Garanaik, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Scaling arguments are presented to quantify the widely used diapycnal (irreversible) mixing coefficient Γ = ∈PE/∈ in stratified flows as a function of the turbulent Froude number Fr = ∈/Nk. Here, N is the buoyancy frequency, k is the turbulent kinetic energy, ∈ is the rate of dissipation of turbulent kinetic energy and ∈PE is the rate of dissipation of turbulent potential energy. We show that for Fr≫1, Γ ∝ Fr^-2, for Fr∼ O (1), Γ ∝ Fr^-1 and for Fr ≪ 1, Γ ∝ Fr⁰. These scaling results are tested using high-resolution direct numerical …

Resurrecting A Fallen Angel: Architecture Remediating Pollution In Mexico City, Karen Rios

Bachelor of Architecture Theses - 5th Year

Mexico City's population of over twenty-one million inhabitants makes it the second largest city in the world. Consequently, air pollution levels in the capital are outrageous.

The following proposal is not an attempt at fixing the city's pollution issues but, rather, presenting an innovative solution to be adopted throughout the city. The thesis aims at solving the contamination crisis' physical and psychological aspects.

That is, a combination of architectural intervention and community involvement will help slow down the rising pollution levels in a once beautiful city. Perhaps starting at a micro scale and spreading throughout the city.

Application Of Effective Noise Control Strategies In Speech Perception Testing Rooms, Samuel H. Underwood

Theses/Capstones/Creative Projects

This project examines experimental methodologies, common test practices, and identifies relevant acoustic metrics to determine effective noise control parameters and strategies for implementation in a new speech perception testing room in Lincoln, Nebraska. The nature of speech perception testing demands that the experiment facility be as quiet and non-disruptive as possible to ensure that auditory stimuli is not interfered with. Influences of ambient acoustic conditions, like background noise and reverberation time, interfere with speech perception testing by introducing new variables that are often difficult to account for if left uncontrolled. A room-in-room chamber (sound booth) is often a best-case practice …

Masters

Natural ventilation is one of the prime form givers in environmentally responsive architecture – in its detail and its architecturally charged form of stacks and voids. It facilitates our understanding of a response to natural systems – not just in how it responds visually to warm and cool air but also in the adaptive approach to thermal comfort. The purpose of this research is to investigate the impacts and implications of natural ventilation strategies for different typologies of public and commercial buildings. This is with the aim of attempting to define a vocabulary of ventilation techniques and details that are …

Automated Generation Of Daily Evacuation Paths In 4d Bim, Kyungki Kim, Yong-Cheol Lee

Durham School of Architectural Engineering and Construction: Faculty Publications

Spatial movements of workers and equipment should be carefully planned according to project plans. In particular, it is crucial for workers’ safety to prepare emergency evacuation paths according to changing construction site configurations and construction progress. However, creating evacuation paths for all crews for each day can be an extremely labor-intensive task if it is done manually. Consequently, in most construction projects, evacuation plans are not provided to managers and crews throughout the entire construction. Even state-of-the-art technologies do not suggest ways to generate evacuation paths according to changing progresses presented in 4-Dimensional Building Information Model (4D BIM). This research …

Tilt-Up Concrete Wall Anchorage Design: A Trial And Error Process, John W. Lawson, David L. Mccormick

Architectural Engineering

Concrete tilt-up buildings are a common subset of a class of building referred to as rigid-wall-flexible-diaphragm (RWFD) structures. Common diaphragm types are plywood, oriented strand board, or metal deck. Masonry wall buildings with flexible diaphragms are also examples of RWFD buildings. Tilt-ups have performed poorly in past earthquakes, with the primary weakness being the anchorage between walls and roof. In the seismically active western United States, design was governed primarily by the Uniform Building Code (UBC) until the advent of the International Building Code (IBC). Before the 1973 UBC, it was common practice by design engineers to use the nailing …
