Masters Theses

Sustainability is quickly becoming a “buzz word” in today’s environmentally conscious world from political leaders to building professionals to design experts to consumers as they rethink their impact on current healthy, efficient indoor/outdoor environments as well as long term benefits to future generations.

This paper seeks to investigate ways to increase the structural engineer’s influence over the sustainability of the building industry by using integrated design teams. It explores current practices within the building industry, in particular the housing industry and the ways in which the integrated design team differs from most current practices. It strives to ...


Failure Literacy In Structural Engineering, Norbert J. Delatte 2010 Cleveland State University

Failure Literacy In Structural Engineering, Norbert J. Delatte

Civil and Environmental Engineering Faculty Publications

The history of the development of practice in many engineering disciplines is, in large part, the story of failures, both imminent and actual, and of the changes to designs, standards and procedures made as the result of timely interventions or forensic analyses. All engineers, and more particularly structural engineers, should be failure literate. Failure literacy means knowing about the critical historical failure cases that have shaped the profession: not merely the surface technical details, but the environment, the communications difficulties and the procedural issues. In the US, an intensive effort has been under way for nearly a decade to promote ...

Scale Model Shake Table Testing Of Underground Structures In Soft Clay, Victor A. Crosariol 2010 California Polytechnic State University - San Luis Obispo

Scale Model Shake Table Testing Of Underground Structures In Soft Clay, Victor A. Crosariol

Master's Theses and Project Reports

Underground structures perform an important role in transportation systems in many seismically active regions around the world, but empirical data regarding the seismic behavior of these structures is limited. This research works towards filling that empirical gap through the use of scale model shake table testing. Underground seismic soil-structure interaction (USSSI) effects were investigated for a stiff rectangular tunnel cross-section embedded within soft clay. San Francisco Young Bay Mud was used as a prototype soil for developing a scale model soil mixture consisting of kaolinite, bentonite, class C fly ash, and water. A single cell Bay Area Rapid Transit (BART ...

Nonlinear Finite Elements Modeling Of Hybrid Reinforced Concrete Beams, Akram Shaker Mahmood 2010 University of Anbar, Iraq

Nonlinear Finite Elements Modeling Of Hybrid Reinforced Concrete Beams, Akram Shaker Mahmood

Akram Shaker Mahmood

This paper presents results from a nonlinear finite element analysis of a hybrid reinforced concrete rectangular section beams. The concept of hybrid R.C. concrete structures was applied in many designers for using in constructions of bridge superstructure. Although using the steel reinforcements are often modeled as a linear-elastic material until failure, the linear finite element analysis could not predict the behavior of the R.C. concrete beams model up to its failure. The materials, loadings, section properties with boundary conditions are taken from reference [Ref.3]. Results from material tests and loading tests of beams model indicated that the ...


Minimum Spiral Reinforcement Requirements And Lateral Displacement Limits For Prestressed Concrete Piles In High Seismic Regions, Ann-Marie Fanous, Sri Sritharan, Muhanned Suleiman, Jin-Wei Huang, Arul K. Arulmoli 2010 Iowa State University

Minimum Spiral Reinforcement Requirements And Lateral Displacement Limits For Prestressed Concrete Piles In High Seismic Regions, Ann-Marie Fanous, Sri Sritharan, Muhanned Suleiman, Jin-Wei Huang, Arul K. Arulmoli

Reports and White Papers

Several code-based equations exist today for design of the minimum transverse reinforcement required in the potential plastic hinge region of prestressed concrete piles. However, the reinforcement requirements of these equations differ drastically in some cases by as much as a factor of three. Furthermore, there is no expectation for the ductility capacity of prestressed pile sections in seismic regions, nor do the code-based equations allow the designer to account for a desired ductility when determining the minimum confinement reinforcement in prestressed concrete piles. For this reason, a rational study presented in this report was undertaken to develop an equation that ...

Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy 2010 Dublin Institute of Technology

Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy

Articles

Ireland is committed to limiting its greenhouse gas (GHG) emissions to 113% of 1990 levels over the period 2008-12 and to 84% of 2005 levels by 2020 under the Kyoto Agreement and the EU’s ’20 20’ by 2020 respectively. National policies have targeted many industry sectors but have failed to directly tackle GHG emissions associated with construction activity. This paper estimates energy and GHG emissions intensities of the Irish construction sector and subsectors and estimates its contribution to Irish national emissions. This information is used to identify and assess the impacts of policy measures which would result in a ...

Simulation Of Traffic Loading On Highway Bridges, Bernard Enright 2010 Dublin Institute of Technology

Simulation Of Traffic Loading On Highway Bridges, Bernard Enright

Other resources

This work is based on weigh-in-motion measurements for approximately three million trucks obtained from sites in five European countries. Techniques have been developed, supported by photographic evidence, for filtering the measurements to identify and remove unreliable values, and for the classification of extremely heavy vehicles. The collected measurements have been used as the basis for building and calibrating a Monte Carlo simulation model for bridge loading. Two-lane traffic is simulated – either two lanes in the same direction or one lane in each direction. The model allows for vehicles that are both heavier and have more axles than in the measured ...

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The superstructure and instrumentation designs of a three-span bridge are presented in this report. The three spans include a precast box-girder bridge, a precast deck on steel girder and a precast deck on concrete girder. They were designed to compare the performance of various bridge decks reinforced with fiber reinforced polymers (FRP) through field instrumentations. A wireless monitoring system was designed to facilitate the collection of field data after the completion of bridge construction. The collected data will allow the study of FRP bars and stay-in-place FRP grid systems.


Identification Of Physical Changes To A Steel Frame, Daniel Eric Means 2010 California Polytechnic State University - San Luis Obispo

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

Master's Theses and Project Reports

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 ...


Development Of Innovative Load Transfer Mechanism To Reduce Hurricane-Induced Failures In New And Existing Residential Construction, Sheikh Saad Ahmed 2010 Florida International University

Development Of Innovative Load Transfer Mechanism To Reduce Hurricane-Induced Failures In New And Existing Residential Construction, Sheikh Saad Ahmed

FIU Electronic Theses and Dissertations

Implicit in current design practice of minimum uplift capacity, is the assumption that the connection's capacity is proportional to the number of fasteners per connection joint. This assumption may overestimate the capacity of joints by a factor of two or more and maybe the cause of connection failures in extreme wind events. The current research serves to modify the current practice by proposing a realistic relationship between the number of fasteners and the capacity of the joint. The research is also aimed at further development of non-intrusive continuous load path (CLP) connection system using Glass Fiber Reinforced Polymer (GFRP ...


Damage Detection In Wind Turbine Blades Using Time-Frequency Analysis Of Vibration Signals, Breiffni Fitzgerald 2010 Dublin Institute of Technology

Damage Detection In Wind Turbine Blades Using Time-Frequency Analysis Of Vibration Signals, Breiffni Fitzgerald

Breiffni Fitzgerald

The dynamic behaviour of modern multi-Megawatt wind turbines has become an important design consideration. One of the major aspects related to the reliability of operation of the turbines concerns the safe and adequate performance of the blades. The aim of this paper is to develop a time-frequency based algorithm to detect damage in wind turbine blades from blade vibration signals. It is important that damage to blades is detected before they fail or cause the turbine to fail. A wind turbine model was developed for this paper. The parameters considered were the rotational speed of the blades and the stiffness ...


Historic Bridge Evaluation Using Finite Element Techniques, Helena M. Charron 2010 University of Massachusetts Amherst

Historic Bridge Evaluation Using Finite Element Techniques, Helena M. Charron

Masters Theses 1911 - February 2014

The present study examined the application of modern, computer-based analysis methods to two existing historic bridges in Massachusetts. The first bridge featured in this study is the Woronoco Bridge, a reinforced concrete open spandrel arch bridge that was constructed in 1923. It was hoped that a computer-based, parametric study of this bridge would prove it to be deck-stiffened, similar to select bridges of Swiss engineer Robert Maillart. However, the results do not support that there was any intent to reduce bending in the arch as a result of increasing the stiffness of the bridge deck. Instead, the Woronoco Bridge appears ...


Material Characterization And Structural Response Of Historic Truss Bridges, Sean L. Kelton 2010 University of Massachusetts Amherst

Material Characterization And Structural Response Of Historic Truss Bridges, Sean L. Kelton

Masters Theses 1911 - February 2014

Historic truss bridges are examined in this thesis through material characterization of wrought iron and structural evaluation of an early 20th century pony truss bridge. The mechanical properties of wrought iron from six 19th century truss bridges were evaluated through mechanical testing that includes hardness and tension tests. The main findings of this work are: 1) That hardness is a poor predictor of yield and ultimate stress but has some ability in screening iron for iron with low ductility, 2) there is a statistically significant difference in the distribution of yield and ultimate stresses between material samples from different bridges ...
