Nonlinear Modeling Of A Sustainable Material, Jorien Gill Baza

Master's Theses

This study developed a nonlinear constitutive model for a sustainable orthotropic material. Existing methods for constitutive models of wood were improved upon to include the nonlinear stress-strain response not only in the two orthogonal axes but at any orientation to the strong axis of the material. This method also simplifies the nonlinear stress-strain relationships into bilinear stress-strain curves which can be valuable in hand calculations as well as finite-element analyses. The effectiveness of the proposed constitutive model is demonstrated by comparing bilinear stress-strain predictions to experimental data.

An Investigation Of The Influence Of Diaphragm Flexibility On Building Design Through A Comparison Of Forced Vibration Testing And Computational Analysis, Blake Alan Roskelley

Master's Theses

An assessment of the validity of idealizing a concrete diaphragm as rigid was performed through the modal analysis of three existing buildings. Modal analysis was performed both by physical experimentation and computational analysis. Experimental determination of the mode shapes shows that two of the three buildings’ diaphragms exhibited flexible behavior. The experimental results were compared to computational analysis results and were shown to be similar, confirming that that the two building diaphragms are not rigid. As a standard, diaphragms with aspect ratios less than three are permitted to be idealized as rigid per ASCE 7-05. To determine the effect of …

Transformation Of Industrial Space, Xin Jia

Masters Theses

By the 1970s the international markets had begun to change and the region’s industries were becoming less competitive. Mines began to close. Factories that had operated night and day fell silent. Their gates closed and they became “brownfield” sites in need of restoration.

For the over past 20 years, city planners regenerated these derelict industrial lands in different ways especially focus on renaturalizing them. Less attention is being paid to them as active and strategic roles in contemporary affairs. Today, people’s thinking about this issue demands more the character of sentimental stimulus- for either the re-creation or preservation of past …

“The City Implant is an urban design project that can be used to strengthen an existing center or create a new one. It is a spatial and programmatic upgrade that gives an area the status of a center or increases the density of an existing center. Rather than intervening in undeveloped land, a City Implant should be a transformer of empty land and even under-exploited traffic junctions. A City Implant should describe the quality of centrality itself.” Alex Wall “Boomtown v. Regiocity: Thinking and designing or the Networked City Region.” (Almy, 286)

[Dis]Lodge; A Transformation Of The Ski Lodge In Response To Function And Site, Jacob E. Schneck

Honors Capstone Projects - All

Over the past century skiing has experienced remarkable growth in popularity, equipment and technique. From 1946 to the present the number of ski resorts in North America with operating lifts has grown from 15 to over 600. During this time skiing has developed from a means of winter travel into a sport that combines paramilitary precision and control with leisure. Driven by economic interests and the superficial imitation of European alpine architecture the contemporary ski lodge model has failed to meaningfully address these changes and has failed to address function and context in terms of both its formal organization and …

Identification Of Physical Changes To A Steel Frame, Daniel Eric Means

Master's Theses

The thesis utilized physical testing and computer modeling to determine the feasibility of identifying a change to the mass or stiffness of a steel frame. Physical testing was performed using an accelerometer, linear shaker, and arbitrary function generator. Two methods of laboratory testing were developed: ambient vibration testing (AVT) and forced vibration testing (FVT). AVT was able to preliminarily identify the natural frequencies and mode shapes of the frame. FVT was able to precisely identify four distinct natural frequencies, mode shapes, and damping ratios. The baseline frame then underwent two physical changes: the addition of mass to its roof, and …

A Study Of The Economical Feasibility Of Installing Heating, Ventilation, And Air-Conditioning Condensate Recovery System, Rafid M. Kully

Theses

The objective of this study is to establish a guide line or an analytical frame work to predetermine the economic benefits associated with the installation of Heating, Ventilation, and Air-Conditioning (HVAC) condensate recovery systems to capture the air-handler’s condensate water and use it as makeup water for the cooling tower. Some factors should be considered such as; the location, building operation, amount of outside air required, type of energy recovery system, and indoor conditions setup. Experimental data was used from Emory University in Georgia, where a condensate recovery system was installed and the condensate water from four air-handler units at …
