Comportamiento estructural de nudos con losas TT de sección constante y de sección variable, con luces de 6, 8, 10 y 12 metros

Abstract

The use of precast concrete elements in the construction of buildings as constructive system in Cuenca has been poor. Prefabricated elements have advantages such as reduce the time of assemblage and cost, improve quality and safety of structures. Different constructive technologies have been developed through prefabrication, but local application requires feasibility studies. However, it’s use is considered positive and convenient. Examples of favorable results in Cuenca are the underground parking at the Parque de La Madre and the School of Engineering of Universidad de Cuenca in Balzay. Even so, there is uncertainty in the structural behavior of connections between precast elements, making it necessary to address the structural analysis of TT slabs nodes. TT slabs of uniform cross section produce deficient nodes, causing discontinuity in the structure. In contrast, TT slabs of variable cross section produce rigid nodes and continuity. The purpose is determining the structural behavior of connections between the prefabricated elements, using software such as SAP2000, where the TT slabs will be modeled in varying cross section and length from 6m to 12m. This will provide information on the structural conditions that allow the application of TT slab variable section in construction. The results will contribute to a solution for the progress of construction in Cuenca and Ecuador, particularly for cases of connections Beam - TT Slab and Wall - TT Slab. Are left further researches involving other types of sections to ensure structural continuity.
