Bicp Global Bim Study - Lessons For Ireland’S Bim Programme, Barry Mcauley, Alan Hore, Roger West

Reports

The Construction IT Alliance (CitA) has been promoting the benefits of digitisation in the construction and engineering industry in Ireland since its formation back in 2002. Whilst the Alliance has always strived to ensure that its members are exposed to a wide spectrum of contemporary digital tools and processes, the concept of Building Information Modelling (BIM) has dominated the focus of its activities over the past five years.

BIM can be described as a digital tool that facilitates everybody to better understand a building or structure through the use of a digital model which draws on a range of data ...


Bim Assisted Design Process Automation For Pre-Engineered Buildings (Peb), Mohammad Delavar 2017 The University of Western Ontario

Bim Assisted Design Process Automation For Pre-Engineered Buildings (Peb), Mohammad Delavar

Electronic Thesis and Dissertation Repository

The effective adoption and implementation of Building Information Modeling (BIM) is still challenging for the construction industry. However, studies and reports show a significant increase in the rate of BIM implementation and adoption in mainstream construction activities over the last five years. In contrast, Pre-Engineered Building (PEB) construction, a specialized construction system which provides a very efficient approach for construction of primarily industrial buildings, has not seen the same uptake in BIM implementation and adoption. The thesis reviews the benefits and the main applications of BIM for the PEB industry as well as challenges of its practical implementation. To facilitate ...


Seismic Behavior Of Concrete Frames With Jacketed Columns, Jose Alvarez 2017 University of Massachusetts - Amherst

Seismic Behavior Of Concrete Frames With Jacketed Columns, Jose Alvarez

Doctoral Dissertations May 2014 - current

Research on jacketed reinforced concrete (RC) columns is well established and growing. The existing studies describe the ability of jackets to rehabilitate RC columns for seismic demands. The system in the studies has proven to upgrade both strength and ductility of their unretrofitted counterparts, concentrated on repairs of deficiencies, currently in columns designed with old code provisions. These deficiencies include: low shear strength, insufficient core confinement, and short lap-splices, in particular within the plastic hinge zone. Columns with these deficiencies usually have brittle failures and cannot develop displacement ductility ( ) greater than 2. Research results on columns retrofitted with jackets have ...


Numerical Computation Of Transient Response Of 2d Wedge Impact, Naresh Kumar Koyyapu 2016 University of New Orleans

Numerical Computation Of Transient Response Of 2d Wedge Impact, Naresh Kumar Koyyapu

University of New Orleans Theses and Dissertations

The diverse applications of advanced marine craft ascribed to their high speed and technological advancements has led to the use of stronger and lighter metals in such crafts. High speed, in effect also increases slamming loads as higher speed increases frequency of wave encounter while operating in waves. The present study is limited to wedge impact models. Fundamentally, the study is thus about two-dimensional (2D) wedge impact in water. In an attempt to predict the structural response to impact hydrodynamic force, a beam element based finite element (FE) computer program is written and the results of the code are presented ...


Investigation Of Grouted Dowel Connection For Precast Concrete Wall Construction, Douglas J. Provost-Smith 2016 The University of Western Ontario

Investigation Of Grouted Dowel Connection For Precast Concrete Wall Construction, Douglas J. Provost-Smith

Electronic Thesis and Dissertation Repository

The grouted dowel connection is a simple and cost-effective connection used in many precast concrete structural systems. The required dowel length is currently designed as a regular bar in reinforced concrete, which underestimates the bond strength, thus resulting in excessive connection lengths. Furthermore, precast wall construction continues throughout cold weather, where in-situ heating of the grout used in the grouted dowel connections is usually conducted for short periods of time. Hence, early-age exposure to subfreezing conditions may affect the quality of the grout and subsequently the bond strength of the connection, which can compromise structural integrity.

In this thesis, full-scale ...

In-Plane Loading Of Brick Veneer Over Wood Shear Walls, Elias Anis Toubia, James M. Lintz 2016 University of Dayton

In-Plane Loading Of Brick Veneer Over Wood Shear Walls, Elias Anis Toubia, James M. Lintz

Elias Toubia

In the design of wood stud walls with brick veneer, current design building codes specify that the wood stud wall should resist all in-plane and out-of-plane loads (IBC 2009). For out-of-plane loads, this assumption is entirely justified as the brittle brick veneer will crack and lose its capacity to resist bending. For in-plane loads, the brick veneer is significantly stiffer than the wood shear wall, and the veneer is unlikely to crack before the wood shear wall reaches its allowable capacity. The assumption that the wood shear wall resists the entire load is based on the further assumption that the ...

The first milestone is conducting, for the first time, a test on an aero-elastic model of a multi-span transmission system under reduced–scale simulated downbursts. The first objective of ...


Condition Factor Calibration For Load And Resistance Factor Rating Of Steel Girder Bridges, Pranav M. Shakya 2016 University of Nebraska - Lincoln

Condition Factor Calibration For Load And Resistance Factor Rating Of Steel Girder Bridges, Pranav M. Shakya

Civil Engineering Theses, Dissertations, and Student Research

The Load and Resistance Factor Rating (LRFR) is a reliability-based rating procedure complementary to the Load and Resistance Factor Design (LRFD). The intent of LRFR is to provide consistent reliability for all bridges regardless of in-situ condition. The primary difference between design and rating is the uncertain severity and location of deterioration, including the potential future loss of strength for an element already evidencing deterioration. Ostensibly, these uncertainties are accounted for by applying an additional strength reduction factor: the condition factor, ϕc. Currently, condition factors are nominally correlated to the condition of the member, which can be Good, Fair ...


Microstructural Analysis Of Thermoelastic Response, Nonlinear Creep, And Pervasive Cracking In Heterogeneous Materials, Alden C. Cook 2016 University of Maine

Microstructural Analysis Of Thermoelastic Response, Nonlinear Creep, And Pervasive Cracking In Heterogeneous Materials, Alden C. Cook

Electronic Theses and Dissertations

This dissertation is concerned with the development of robust numerical solution procedures for the generalized micromechanical analysis of linear and nonlinear constitutive behavior in heterogeneous materials. Although the methods developed are applicable in many engineering, geological, and materials science fields, three main areas are explored in this work. First, a numerical methodology is presented for the thermomechanical analysis of heterogeneous materials with a special focus on real polycrystalline microstructures obtained using electron backscatter diffraction techniques. Asymptotic expansion homogenization and finite element analysis are employed for micromechanical analysis of polycrystalline materials. Effective thermoelastic properties of polycrystalline materials are determined and compared ...


Relaxation In Bolted Assemblies, Samuel Augustus Moeller 2016 Rowan University

Relaxation In Bolted Assemblies, Samuel Augustus Moeller

Theses and Dissertations

The purposes of this investigation were to (a) extend previously developed elastic spring models for bolt assemblies to include simulating creep loss in the bolt and the threads and (b) to present an approach in which appropriate spring stiffness in the model are determined rationally. Previous efforts at modeling tension in bolts have been limited in that they were not readily applicable to analyses of realistic bolted connections. The simulated load distributions on the shank and the threads in a single-bolt assembly showed good comparison to the gathered experimental data as did the simulated, time dependent creep loss in the ...


Chloride Contamination Remediation On Steel Bridges, Bobby W. Meade, Christopher Goff, Sudhir Palle, Theodore Hopwood II 2016 University of Kentucky

Chloride Contamination Remediation On Steel Bridges, Bobby W. Meade, Christopher Goff, Sudhir Palle, Theodore Hopwood Ii

Kentucky Transportation Center Research Report

Researchers evaluated 32 steel surface preparation methods to determine how effectively they remove chloride from corroded chloride-contaminated steel panels. Wet methods proved more effective than dry methods. The three most effective wet methods injected mineral slag abrasives in a water stream and resulted in less than 1% chlorides remaining. Most dry surface preparation methods left significantly more chloride contamination after surface preparation. The three most effective dry methods used multiple blast cleaning cycles. These methods approached the effectiveness of the best wet methods, with 1.6 to 2.0% chlorides remaining. The least effective surface preparation was a single abrasive ...

Extending Use Of Simple For Dead Load And Continuous For Live Load (Sdcl) Steel Bridge System To Seismic Areas, Ramin Taghinezhadbilondy 2016 Florida International University

Extending Use Of Simple For Dead Load And Continuous For Live Load (Sdcl) Steel Bridge System To Seismic Areas, Ramin Taghinezhadbilondy

FIU Electronic Theses and Dissertations

The steel bridge system referred to as Simple for Dead load and Continuous for Live load (SDCL) has gained popularity in non-seismic areas of the country. Accordingly, it results in many advantages including enhanced service life and lower inspection and maintenance costs as compared to conventional steel systems. To-date, no research studies have been carried out to evaluate the behavior of the SDCL steel bridge system in seismic areas. The main objective of this research was to extend the application of SDCL to seismic areas.

The concept of the SDCL system was developed at the University of Nebraska-Lincoln and a ...


Restoring Capacity In Compromised Glued Laminated Beams, Cole Moller 2016 Montana Tech

Restoring Capacity In Compromised Glued Laminated Beams, Cole Moller

Graduate Theses & Non-Theses

After structural fires are extinguished, presuming the structure is not a total loss, structural wood members can be inspected for residual properties. Through this research, we explored alternative methods aimed at keeping structurally compromised wood member’s in service when they would otherwise warrant replacement. For this study, we used 24F-V8 DF/DF glued laminated beams that had been loaded to their max capacity; both non-fire damaged and fire damaged. In situations where physical and mechanical changes occur, and the beam warrants individual replacement, a new restoration procedure could be used to salvage the member. Salvaging the member could mean ...


Efficient Domain Decomposition Algorithms And Applications In Transportation And Structural Engineering, Paul W. Johnson III 2016 Old Dominion University

Efficient Domain Decomposition Algorithms And Applications In Transportation And Structural Engineering, Paul W. Johnson Iii

Civil & Environmental Engineering Theses & Dissertations

Domain decomposition is a divide-and-conquer strategy. In the first part of this dissertation, a new/simple/efficient domain decomposition partitioning algorithm is proposed to break a large domain into smaller sub-domains, in such a way as to minimize the number of system boundary nodes and to balance the work load for each sub-domain. This new domain decomposition algorithm is based on the network’s shortest path solution. Numerical results indicate that the new Shortest Distance Decomposition Algorithm outperformed the most widely used METIS algorithm in 21 out of 27 tested (transportation) examples. In the second part of this dissertation, another ...

The concept of Lean Construction has been introduced successfully into the Construction Industry to increase efficiency and profit by elimination of non-value adding activities or ‘Waste’. Lean Construction is an adaptation of Lean manufacturing principles and is the future of the Construction Industry in developing as well as developed countries. There has been much study and documentation conducted on ‘Lean Construction’ in USA. Even though people have started practicing Lean in India, there is lack of documented information available about it. Professionals within the Industry could already be minimizing ‘Waste’ and/or following Lean principles without the knowledge of the ...


Enhancing The Seismic Performance Of Steel Structures Utilizing Superelastic Shape Memory Alloys, Papia Sultana 2016 The University of Western Ontario

Enhancing The Seismic Performance Of Steel Structures Utilizing Superelastic Shape Memory Alloys, Papia Sultana

Electronic Thesis and Dissertation Repository

Although conventional earthquake-resisting structural systems provide the life safety level during earthquakes, they experience significant structural damage when exposed to strong ground shaking that render structural retrofitting as uneconomical. Superelastic shape memory alloys (SMAs) can be used in steel structures to reduce the residual deformations due to their recentering capability, which can facilitate post-seismic retrofitting. The primary aim of this thesis is to enhance the seismic performance of both regular and modular steel structures using an optimum amount of superelastic SMAs material in terms of maximum inter-storey drift, residual drift, and damage scheme.

First, a simplified method based on pushover ...
