FRP BOND STRENGTH DEGRADATION: AN EXPERIMENTAL STUDY USING PULL-OFF TESTING

by

CLARISSE MACHADO MIKAMI

Advisor: Dr. Hwai-Chung Wu

Major: Civil Engineering

Degree: Master of Science

Fiber reinforced polymer (FRP) is an advanced composite material that has been employed efficiently to rehabilitate deteriorated concrete structures. Environmental factors, however, affect the durability performance of FRP. As bond at the interfacial region between FRP and concrete is essential to the overall integrity of the system, the focus of this thesis is on bond deterioration due to hot weathering conditions.

In this study, an experimental program was developed to investigate the …

ABSTRACT

RELIABILITY AND EFFECT OF PARTIALLY RESTRAINED WOOD SHEAR WALLS

JOHN J. GRUBER

Advisor: Dr. Gongkang Fu

Major: Civil Engineering

Degree: Doctor or Philosophy

The prescriptive design of the most widely used residential building code in the United States, the IRC, allows the use of partially restrained wood shear walls to resist wind and seismic loads. Wind load is the most common controlling lateral design load for these structures. In contrast, the complimenting building code, the IBC, requires either a restraining dead load or a mechanical hold down device to resist overturning. To prescribe a safe structure, …

Timing Of Residential Electric Loads To Reduce Air Emissions From Power Generation, Michelle Marinich Rogers

Wayne State University Theses

Over the course of a day, power utilities must respond to changing demand by dispatching or shedding output from different generators. Each generator is associated with a unique profile of air emissions, based on the type of fuel consumed, installed pollution controls, and the generator's efficiency. The aim of this study is to determine whether shifting electric demand to times when cleaner generation sources are available would result in overall emissions reduction.

Dynamic wholesale pricing in the electric power market, specifically the Locational Marginal Price (LMP), provides a means to estimate the marginal generator fuel type. This knowledge was used …

Reliability Model For Ductile Hybrid Frp Rebar Using Randomly Dispersed Chopped Fibers, Bashar Ramzi Behnam

Wayne State University Dissertations

RELIABILITY MODEL FOR DUCTILE HYBRID FRP REBAR USING RANDOMLY DISPERSED CHOPPED FIBERS

Fiber reinforced polymer composites or simply FRP composites have become more attractive to civil engineers in the last two decades due to their unique mechanical properties. However, there are many obstacles such as low elasticity modulus, non-ductile behavior, high cost of the fibers, high manufacturing costs, and absence of rigorous characterization of the uncertainties of the mechanical properties that restrict the use of these composites. However, when FRP composites are used to develop reinforcing rebars in concrete structural members to replace the conventional steel, a huge benefit can …

There are more than nine million construction workers in the US. Roofers and steel workers are the highest risk construction trades according to BLS, and fall from elevation accounts for a large percentage of fatalities and injuries among the construction trades.

In this study, 2114 OSHA accident case reports involving roofers and steel workers were …
