Influencia de la pendiente de la cartela en los extremos cerrados de Losas TT de 8, 10,12, 14, 16 metros de luz

Abstract

Prefabricated floor slabs section TT have proven to be "rational" in the production of buildings roofs and floors. In Cuenca, they occur in the prefabrication plant, Construcciones RFV, in Guayaquil, in the company MAVISA. In both cases, this prefabricated slab cross-section, whose supports would be an articulated scheme. The structural designer, director of this thesis, introduced the closed-end solution in Slabs TT in the design of the parking of Mother’s park. Two graduation thesis of this faculty show the advantage of the closed solution against open-ended. For this reason, this paper will examine the slope influence of the gusset of the end zones in the structural behavior of slabs for different lengths. Its scientific basis indicates a high practical and influence felt in the construction technology. The objective: determine the influence of the slope of the gusset at the ends of slabs TT, with range of values that maximizes stiffness in nodes. With the analysis of structural models and programs like SAP 2000, among others. Determining expected: optimum slopes of the gusset in the closed ends of the double T slabs and the optimum range of said slope for better structural behavior. The design and construction of these structures should use the optimum slope range found in this thesis, maximizing the rigidity of these unions.
