Modular Composite Sandwich Structures For Thermal And Structural Retrofitting Of Existing Buildings, Marc Al Ghazal
Modular Composite Sandwich Structures For Thermal And Structural Retrofitting Of Existing Buildings, Marc Al Ghazal
Masters Theses
Around 40% of global energy consumption and 30% of worldwide carbon dioxide (CO2) emissions are attributed to buildings. Most of this consumption is dedicated to ensuring thermal comfort. The goal of this research was to develop and field validate retrofit solutions to improve the energy efficiency of buildings. Exterior cladding panels were designed and tested to ensure adequate thermal and structural performance. Sandwich panels (glass fibers reinforced polymer (GFRP) skins and polymeric foam cores) were fabricated using the vacuum assisted resin transfer molding (VARTM) process. Extruded polystyrene (XPS) and polyurethane (PU) foams were compared as core materials through a series …
The Current State Of Practice Of Building Information Modeling, Kevin P. Brooks
The Current State Of Practice Of Building Information Modeling, Kevin P. Brooks
Masters Theses
Building Information Modeling (BIM) has become extremely prominent in the construction industry in the past twenty years. It serves as a digital repository that can, when used to its fullest potential, combine all aspects of designing, building, and managing a structure in one place, alongside all the data produced in those processes. The construction industry has to date struggled to increase productivity alongside similar fields, such as the manufacturing industry, though the construction industry generally has far more stakeholders on one project than the manufacturing industry. Further, building designs are becoming more complex while project schedules are becoming tighter. As …

Verifying Automated Prestressed Concrete Design Software For Mdot Bridge Design Standards, Hussein Kadhim Abood Khalaf
Masters Theses
The design and analysis of bridges is a very critical and time consuming process. The automation of bridges design can save us time and effort, but the designer must have enough background with structural design of bridges in order to be able to analyze and understand the output of the automated design. This research shows the design and analysis of the superstructure of the US-27 Interchange Bridge at M-57 in Gratiot County of Washington Township, Michigan. The main purpose of this research is to establish a comprehensive design example following AAHTO LRFD Bridge Design Specifications and Michigan Bridge Design Manual. …

Developing Standard Procedures For Structural Aspects Of Slide-In Bridges In Accelerated Bridge Construction (Abc), Ozan Utku Ridvanoglu
Masters Theses
Slide-in bridge construction (SIBC) is a special method especially used to replace an existing bridge with the minimum duration road closure. In this method, new bridge superstructure is built next to the existing one and it is slid to its final position after demolishing the existing one. Applied implementations of SIBC show that several complications are experienced during bridge slide related with surface interaction. There is a need to evaluate the structural components of SIBC to develop suggestions. In this research, structural components of SIBC were investigated. The research dealt with completed SIBC implementations and numerical modelling of the slide …
Durability Of Lightweight Concrete For Bridge Decks, Andrew Mccullough Wagner
Durability Of Lightweight Concrete For Bridge Decks, Andrew Mccullough Wagner
Masters Theses
As concrete durability becomes a higher priority for departments of transportation’s acceptability of concrete for bridge decks, consideration of resistance to the penetration of chloride ions has become a key consideration in defining durability. For years the “Rapid Chloride Ion Penetration (RCP) test has been the accepted standard to measure penetrability of concrete to chloride ions. With the movement to use chloride ion penetrability as a part of acceptance criteria for a concrete mix, use of the newer and easier Surface Resistivity (SR) test as an alternative to the slower, more complicated “Rapid Chloride Ion” test became a desirable option. …
Efficacy Of A Ternary Blend In Improving Bridge Deck Concrete Durability In Tennessee, Robert Clark Nidiffer
Efficacy Of A Ternary Blend In Improving Bridge Deck Concrete Durability In Tennessee, Robert Clark Nidiffer
Masters Theses
A study related to the durability of bridge deck concrete in the state of Tennessee has been ongoing at the University of Tennessee (UT) for the past decade. The most recent phase of this research was begun in the fall of 2009 with a focus on developing assessment criteria and methodology to assess the durability of bridge deck concrete in the state of Tennessee. The methodology that was used to assess the durability of Tennessee bridge deck concrete was to determine the concrete’s resistance to chloride ion penetration by way of two test methods, the Surface Resistivity (SR) test and …
