dc.description.abstract | Este trabajo presenta un resumen de los resultados obtenidos de la investigación realizada durante los estudios de doctorado. Inicialmente la propuestra del trabajo de grado consistía en la obtención de la "Matriz de rigidez y vector de carga de una viga de Timoshenko de dos capas" (ver Capítulo 5), sin embargo se ha adjuntado a este documento otros capítulos que se encuentran intimamente relacionados y que fueron también fruto del trabajo de investigación. Los capítulos 1 y 2 presentan la formulación teórica y la verificación con ejemplos, respectivamente, de la matriz de rigidez y el vector de carga de una viga pretensada incluyendo los efectos de largo plazo. El capítulo 3 presenta el análisis de segundo orden de una viga columna sobre fundación elástica con deflección inicial y conexiones semirrigidas. Los capítulos 4, 5 y 6 presentan el análisis de una viga de Timoshenko de dos capas. En el capítulo 4 se presenta la formulación para un sólo elemento, en el capítulo 5 se presenta la derivación de la matriz de rigidez y se hace la verificación con aplicaciones al diseño de vigas mixtas de acero y concreto. Finalemnte en el capitulo 6 se usa la formulación desarrollada en el capítulo 5 para realizar el análisis de nudos adhesivados. Los capitulos 3 al 6 cuentan con el identificador único y permanente para las publicaciones electrónicas (DOI) en el encabezado de cada capítulo para una fácil referencia. |
dc.description.abstract | Initially, the proposal of the degree work consisted of obtaining the "Stiffness matrix and loading vector of a two-layer Timoshenko beam" (see Chapter 5 and 6), however it has been attached to this document other chapters that are closely related and that were also the result of the research work of these years. Chapters 1 and 2 present the theoretical formulation and verification with examples, respectively, of the stiffness matrix and load vector of a prestressed beam including long-term effects. Chapter 3 presents the second order analysis of a column beam on elastic foundation with initial deflection and semi-rigid connections. Chapters 4, 5 and 6 present the analysis of a two-layer Tymoshenko beam. In chapter 4 the formulation for a single element is presented, in chapter 5 the bypass of the stiffness matrix is presented and verification is made with applications to the design of mixed steel and concrete beams. Finally in chapter 6 the formulation developed in chapter 5 is used to perform the analysis of adhesive joints. Chapters 3 through 6 have the unique and permanent Digital Object Identifier (DOI) in the heading of each chapter for easy reference. |
