ESTUDIO TEÓRICO-EXPERIMENTAL DEL DISEÑO DE CONEXIONES COLUMNA-ZAPATA CON ELEMENTOS PREFABRICADOS DE HORMIGÓN.

Abstract

The purpose of this theoretical-experimental work is to promote the construction of buildings in an industrialized way, which is to say that their structural elements are precast concrete. To do this, the advantages of this constructive methodology are first pointed out. Then the controversial problem based on the connections of the structural components due to the lack of regulations that support them in Ecuador was mentioned. So, to start the study of the connections connecting creating reliability in terms of security, this research work is based on the analysis of the column-foundation connection, choosing two types of connection called: "Connection with Projection Bars" and "Socket Foundation Connection”. Therefore, for an effective study, a theoretical and analytical analysis was first performed. Then a finite element model was made in SAP200, then an experimental trial was carried out by means of an extraction test at the Center of Structural Research (CEINVES); and finally, through the analysis of results, the formulas and design criteria are used to carry out these types of connections in an optimal and safe way.
