Prueba Piloto Para La Implementación De Modelación Numérica Del Comportamiento Esfuerzo Deformación En Mampuestos Suelo Pet Mspet, Paula Andrea Sánchez Navas
Ingeniería Civil
Con el fin de incentivar y dar a conocer una nueva alternativa con materiales no convencionales, el presente trabajo de grado abordo el análisis preliminar de una modelación numérica teniendo en cuenta el comportamiento de una estructura a partir de mampostería MSPET con elementos finitos por medio de programas estructurales. Como bien se sabe la mampostería reside en la construcción por medio de la unión de elementos rígidos que en el caso de esta investigación se desarrolla a partir de un envase PET (plástico derivado del petróleo que no es biodegradable) relleno de cualquier tipo de suelo, refiriéndose a este, …
Non-Linear Analysis Of Steel Fiber Reinforced Concrete Hollow Columns Under Uniaxial Bending, Mohammed Huzaifa Ghori
Non-Linear Analysis Of Steel Fiber Reinforced Concrete Hollow Columns Under Uniaxial Bending, Mohammed Huzaifa Ghori
Civil Engineering Theses
This study investigates the performance of Steel Fiber Reinforced concrete hollow columns under axial compressive load and uniaxial bending with varying amounts of steel fiber using Finite Element Method of Analysis. The columns are of two groups, one with a 10% void and the other group has 20% void at the center. Each group’s specimens’ fiber content is varied in 0.5% increments from 0 to 1.5%. Also, the collapse load of the columns was obtained. Numerical results were compared with the available experiments. Two parametric studies were conducted by varying the amount of void percentages and steel fiber contents. In …
Comparison Study Between Fem And Sem For Wave Propagation Models Applied To Solids, Shaddy Roberto Castillo Ponton
Comparison Study Between Fem And Sem For Wave Propagation Models Applied To Solids, Shaddy Roberto Castillo Ponton
Open Access Theses & Dissertations
Wave propagation is a field whose application has spread across many disciplines. In the field of structural engineering, wave propagation methods have focused their attention specifically in the area of structural health monitoring and active control of vibrations and noise. Likewise, the development of new methods and their application have been successful in the area of material science with a special emphasis on the field of structural integrity evaluation of anisotropic and inhomogeneous structures (laminated composite structures). The current available analysis tools are inadequate to handle the modeling of complex structures. One-dimensional wave propagation problems in solids are still a …
Target Element Sizes For Finite Element Tidal Models From A Domain-Wide, Localized Truncation Error Analysis Incorporating Botto, Denwood Parrish
Target Element Sizes For Finite Element Tidal Models From A Domain-Wide, Localized Truncation Error Analysis Incorporating Botto, Denwood Parrish
Electronic Theses and Dissertations
A new methodology for the determination of target element sizes for the construction of finite element meshes applicable to the simulation of tidal flow in coastal and oceanic domains is developed and tested. The methodology is consistent with the discrete physics of tidal flow, and includes the effects of bottom stress. The method enables the estimation of the localized truncation error of the nonconservative momentum equations throughout a triangulated data set of water surface elevation and flow velocity. The method's domain-wide applicability is due in part to the formulation of a new localized truncation error estimator in terms of complex …
The Effect Of Tidal Inlets On Open Coast Storm Surge Hydrographs: A Case Study Of Hurricane Ivan (2004), Michael Salisbury
The Effect Of Tidal Inlets On Open Coast Storm Surge Hydrographs: A Case Study Of Hurricane Ivan (2004), Michael Salisbury
Electronic Theses and Dissertations
Florida's Department of Transportation requires design storm tide hydrographs for coastal waters surrounding tidal inlets along the coast of Florida. These hydrographs are used as open ocean boundary conditions for local bridge scour models. At present, very little information is available on the effect that tidal inlets have on these open coast storm tide hydrographs. Furthermore, current modeling practice enforces a single design hydrograph along the open coast boundary for bridge scour models. This thesis expands on these concepts and provides a more fundamental understanding on both of these modeling areas. A numerical parameter study is undertaken to elucidate 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 …
