Below-Grade Structural Flexibility Study For Seismic-Resistant, Self-Centering, Concentrically- Braced Frames, Derek A.J. Hauff Jan 2016

Below-Grade Structural Flexibility Study For Seismic-Resistant, Self-Centering, Concentrically- Braced Frames, Derek A.J. Hauff

Honors Research Projects

Self-centering, concentrically braced frames (SC-CBFs) are seismic-resistant lateral-load resisting systems for buildings that increase the lateral drift capacity in comparison to conventional CBFs. Two different substructures were examined on a six-story and a ten-story building to see which below grade structure was more efficient and how the flexibility from the addition of a basement compares to previous research of SC-CBFs structures without basements.

The study was completed in phases: modeling of forces in SAP2000, sizing of structural members, coding of structure into the modeling program Open System for Earthquake Engineering Simulation (OpenSees), and comparison of the output data.

Tropical Cyclone Wind Hazard Assessment For Southeast Part Of Coastal Region Of China, Sihan Li

Electronic Thesis and Dissertation Repository

Tropical cyclone (TC) or typhoon wind hazard and risk are significant for China. The return period value of the maximum typhoon wind speed is used to characterize the typhoon wind hazard and assign wind load in building design code. Since the historical surface observations of typhoon wind speed are often scarce and of short period, the typhoon wind hazard assessment is often carried out using the wind field model and TC track model. For a few major cities in the coastal region of mainland China, simple or approximated wind field models and a circular subregion method (CSM) have been used ...

Math Is Not A Spectator Sport: Student-Driven Problem Solving In The Classroom, Allen O'Hara Aug 2015

Math Is Not A Spectator Sport: Student-Driven Problem Solving In The Classroom, Allen O'Hara

Teaching Innovation Projects

One of the most important overlooked components in mathematics education is ensuring that students understand the logic and proof process. This workshop addresses this gap in pedagogy by introducing university math lecturers to two strategies for teaching the experimental nature of math results. The first strategy (problem-solving methods) involves describing the reasoning behind mathematical proofs (i.e., a series of logical statements establishing a conclusion from given premises), and the second strategy (student-driven problem solving) puts undergraduate students in charge of solution development using guided discussion and collaboration. While the first method teaches the tools of proof and allows the ...

Stochastic Stability And Uncertainty Quantification Of Ring-Based Vibratory Gyroscopes, Soroush Arghavan Aug 2015

Stochastic Stability And Uncertainty Quantification Of Ring-Based Vibratory Gyroscopes, Soroush Arghavan

Electronic Thesis and Dissertation Repository

Effect of stochastic fluctuations in angular velocity on the stability of two DOF ring-type MEMS gyroscopes is investigated. The governing Stochastic Differential Equations are discretized using the higher-order Milstein scheme in order to numerically predict the system response assuming the fluctuations to be white noise. Simulations via Euler scheme as well as a measure of Largest Lyapunov Exponents are employed for validation purposes due to lack of similar analytical or experimental data. The stability investigation predicts that the threshold fluctuation intensity increases nonlinearly with damping ratio. Under typical gyroscope operating conditions, nominal input angular velocity magnitude and mass mismatch appear ...

Calcium looping (CaL) is a recent technology for carbon capture from coal fired power plants which consumes less energy than other approaches such as oxy-fuel. In the first part of this thesis, a system level model is developed in ASPEN PLUS to calculate the energy penalty of introducing Calcium looping in a coal fired power plant. Several simplifications and assumptions are made to model the Calcium looping process. The relationship between the energy penalty due to CaL and carbon capture efficiency is used to validate the process model for both pre-combustion CaL and post-combustion CaL; it agrees well with the ...


Spontaneous Firing Of Sensory Neurons Modulates The Gain In The Downstream Circuit Of A Simple Olfactory System, Matthew O'Neill Aug 2015

Spontaneous Firing Of Sensory Neurons Modulates The Gain In The Downstream Circuit Of A Simple Olfactory System, Matthew O'Neill

Engineering and Applied Science Theses & Dissertations

In locusts and other insects, odorants are transduced into electrical signal by the olfactory receptor neurons and transmitted to central circuits for further processing. Previous studies have shown that exogenous variables (e.g., flow rates, humidity, temperature, odor mixtures, etc.) can influence the responses of the sensory neurons and therefore modulate the central circuits. However, how the sensory neuron activity is manipulated to achieve adaptive gain control in the following circuit is yet to be understood. It is possible that the magnitude of the stimulus-evoked response in the receptor neurons, their spontaneous activity, or both of these factors can change ...
