Estado Del Arte De La Conexión Del Transporte Público Aeropuerto Ciudad, Jesús Anibal Pardo Rodriguez

Ingeniería Civil

El aeropuerto es uno de los centros de movimiento de pasajeros más importantes en una ciudad, generando así una conexión para transportar a las personas desde la terminal aérea al centro metropolitano. Para que esta unión sea posible, es necesaria una infraestructura organizada de los medios de transporte público, ya que son estos hacen posibles los desplazamientos. El desarrollo de las ciudades ha sido una constante con el paso del tiempo, uno de los indicadores de este es el aeropuerto con el que están dotados, estos empezaron siendo pequeños aeroparques que se han convertido en grandes terminales en la actualidad. …

Evaluation Of Redundancy Of Twin Steel Box-Girder Bridges, Huy V. Pham

FIU Electronic Theses and Dissertations

Based on the definition given in the AASHTO LRFD Bridge Design Specifications, twin steel box-girder bridges are classified as bridges with fracture critical members (FCMs), in which a failure of a tension member is expected to lead to a collapse of the bridge. However, a number of such bridges with either a partial or full-depth crack in one girder have been reported and are still providing service without collapsing. The main objective of this research project is to understand the behavior of twin steel box-girder bridges and to develop methods for evaluating their redundancy level in the event of the …

Reflecting Societal Values In Designing Flood Risk Management Strategies, Mark Adamson, John O'Sullivan, Zeinab Bedri

Conference papers

In 2006, the Office of Public Works (OPW) began the National Catchment-based Flood Risk Assessment and Management (CFRAM) Programme through a series of pilot studies. A Multi-Criteria Analysis (MCA) Framework was developed through the pilot studies that integrated a number of objectives related to a wide range of potential impacts and benefits into the core of process of appraising and selecting suitable flood risk management measures for a given area or location, and then for prioritising national investments for different schemes and projects. This MCA Framework, that provides a systematic process of developing a non-monetised but numerical indicator of benefit …

Evaluation Of Slope Stability Quantifying The Effect Of Vegetation, Roberto José Marín, Juan Pablo Osorio

Conference papers

The present study evaluates the shallow landslides susceptibility triggered by rainfall by means of multiple numerical simulations. The simulations integrate a transient rainfall infiltration model with an infinite slope stability model, both of them developed for unsaturated soils in a basin scale. TRIGRS’ infiltration model is used to calculate pore water pressure. The geotechnical model includes the evaluation of two parameters related to vegetation: root reinforcement and tree surcharge due to the weight of the vegetation. These simulations were carried out using multiple values of these parameters so that their behavior is analyzed for the topographic conditions of the watershed …

High-Affinity Phosphate-Binding Protein (Pbp) For Phosphorous Recovery: Proof Of Concept Using Recombinant Escherichia Coli, Yu Yang, Wendy Ballent, Brooke Mayer

Civil and Environmental Engineering Faculty Research and Publications

Phosphorus (P) is a critical, non-renewable nutrient; yet excess discharges can lead to eutrophication and deterioration of water quality. Thus, P removal from water must be coupled with P recovery to achieve sustainable P management. P-specific proteins provide a novel, promising approach to recover P from water. Bacterial phosphate-binding proteins (PBPs) are able to effectively remove phosphate, achieving extremely low levels in water (i.e. 0.015 mg-P L⁻¹). A prerequisite of using PBP for P recovery, however, is not only removal, but also controlled P release, which has not yet been reported. Phosphate release using recombinant PBP-expressing Escherichia coli …

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 to keep …

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 new/simple and highly …

Dynamic Elasto-Plastic Behavior Of Steel Building Sub-Assemblage Including Cfrp Retrofitting Under Impact Load, Ali Mohammed Salih Aloosi

Civil & Environmental Engineering Theses & Dissertations

This dissertation presents the outcome of a theoretical and experimental study of the dynamic as well as the quasi-static elasto-plastic behavior of a steel building sub-assemblage including carbon fiber reinforced polymer (CFRP) retrofitting. The steel sub-assemblage consists of a beam-column attached to a pair of beams at its top end while its bottom end is fixed. An apparatus is constructed and used for conducting a series of experiments by applying a lateral impact load on the beam-column in the presence or absence of a static axial load. An innovative procedure for determining the shape of the forcing function caused by …

Changing Trends In Wave Heights In The U.S. Mid-Atlantic Region, Hillary Lane

Civil & Environmental Engineering Theses & Dissertations

The pace and effects of climate change are an area of constant focus for coastal engineers as evolving patterns in the atmosphere worldwide affect the oceans and coasts on a regional and global scale. Surface waves respond to changing wind patterns both locally and from propagating swell, and the difficulty in predicting future wind patterns is well-established. Expectations that climate change will result in more frequent and intense coastal storms and consequently greater wave heights in the North Atlantic are still unrealized, and recent forecasts from a variety of atmosphere-ocean coupled global climate models instead predict decreasing wave heights through …

Numerical Studies For Improving Fracture Toughness Resistance Curve Testing Using Single-Edge (Notched) Tension Specimens, Yifan Huang

Electronic Thesis and Dissertation Repository

The fracture toughness resistance curve, i.e. the J-integral resistance curve (J-R curve) or the crack tip opening displacement resistance (CTOD-R) curves, is widely used in the integrity assessment and strain-based design of energy pipelines with respect to planar defects (i.e. cracks). This thesis deals with issues related to the experimental determination of the J(CTOD)-R curves using the newly-developed single-edge (notched) tension (SE(T)) specimens. In the first study, the plastic geometry factor, i.e. the η_pl factor, used to evaluate J in a J-R curve test based on …

Innovating Two-Stage Concrete With Improved Rheological, Mechanical And Durability Properties, Manal F. Najjar

Electronic Thesis and Dissertation Repository

Two-stage concrete (TSC), also known as preplaced aggregate concrete, is a special type of concrete that is produced using a unique procedure which differs from that of conventional concrete. TSC is distinguished by its high coarse aggregate content and exceptional placement technique, whereby aggregates are first pre-placed in the mold then injected with a special grout. The preplacement of aggregates saves substantial energy since only the grout needs mechanical mixing; the grout is self-leveling and needs no vibration and no mechanical compaction. However, TSC applications are still limited despite substantial advancement of modern concrete technology. Therefore, there is a need …
