Failure Mode Identifications Of Rc Beams Externally Strengthened With, Chris O'Riordan-Adjah
Failure Mode Identifications Of Rc Beams Externally Strengthened With, Chris O'Riordan-Adjah
Electronic Theses and Dissertations
The application of carbon reinforced-fiber polymers (CFRP) to structures is a new development that is still under intense research. However, the rehabilitation or retrofit of damage reinforced concrete members by the external bonding of CFRP is becoming increasingly popular in the construction industry. The objective of the tests presented in this thesis is to study different CFRP designs on the reinforced concrete beams and compare their failure modes. The main goal is to determine the CFRP design on the reinforced concrete beams that result in a progressive and gradual failure mode with enough warning before final failure. Different CFRP designs …
Effects Of The Soil Properties On The Maximum Dry Density Obtained Fro, Andres Arvelo
Effects Of The Soil Properties On The Maximum Dry Density Obtained Fro, Andres Arvelo
Electronic Theses and Dissertations
In the construction of highways, airports, and other structures, the compaction of soils is needed to improve its strength. In 1933 Proctor developed a laboratory compaction test to determine the maximum dry density of compacted soils, which can be used for specifications of field compaction. The Compaction of soils is influenced by many factors, the most common are the moisture content, the soil type and the applied compaction energy. The objective of this research is the analysis of the maximum dry density values based on the soil classification and characterization. The method of choice in the determination of the maximum …
Detection And Evaluation Of Exisiting Pavement System With Brick Base, Karishma Desai
Detection And Evaluation Of Exisiting Pavement System With Brick Base, Karishma Desai
Electronic Theses and Dissertations
At the turn of the century, the City of Orlando initiated the "Neighborhood Horizon Program." This program involved local citizens to help improve their community resources by engaging in a process of planning where the problems associated with the communities were identified. Many residents favored to bring back the brick roads that were overlaid with asphalt concrete to provided better transportation in the mid 1900s. With majority of the neighborhood streets already bricked, removing asphalt ensured safety, served as a technique for slowing traffic, and added to the historical integrity. Since there were no official documentations available that stated the …
Two Dimensional Linear Finite Element Analysis Of Post-Tensioned Beams, Rodolfo Hutchinson
Two Dimensional Linear Finite Element Analysis Of Post-Tensioned Beams, Rodolfo Hutchinson
Electronic Theses and Dissertations
The objective of this research project was to create a Finite Element Routine for the Linear Analysis of Post-Tensioned beams using the program CALFEM® [20] developed at the division of Structural Mechanics in Lund University, Sweden. The program CALFEM and our own made files were written in MATLAB, an easy to learn and user-friendly computer language. The approach used in this thesis for analyzing the composite beam consists in embedding the steel tendons at the exact location where they intersect the concrete parent elements, without moving the concrete parent element nodes. The steel tendons are represented as one dimensional bar …
Modeling Crash Frequencies At Signalized Intersections In Central Flor, Smitha Kowdla
Modeling Crash Frequencies At Signalized Intersections In Central Flor, Smitha Kowdla
Electronic Theses and Dissertations
A high percentage of highway crashes in the United States occur at intersections. These crashes result in property damage, lost productivity, injury, and even death. Identifying intersections associated with high crash rate is very important to minimize future crashes. The purpose of this study is to develop efficient means to evaluate intersections, which may require safety improvements. The area covered by the analysis in this thesis includes Orange and Seminole Counties and the City of Orlando. The aforementioned counties and city thus represent Central Florida. Each County/City provided data that consisted of signalized intersection drawings that were either in the …

Slope Stability Analysis Of Class I Landfills With Co Disposal Of Bios, Mrutyunjay Vajirkar
Electronic Theses and Dissertations
Land filling provides a major, safe, and economical disposal route for biosolids and sludges. With an expanding world, the demand for larger and higher capacity landfills is rapidly increasing. Proper analysis and design on such fills have pushed the boundaries of geotechnical engineering practice, in terms of proper identification and assessment of strength and deformation characteristics of waste materials. The engineering properties of Municipal Solid Waste (MSW) with co-disposal of biosolids and sludges with regards to moisture characteristics and geotechnical stability are of utmost importance. Significant changes in the composition and characteristics of landfill may take place with the addition …
