Ítem Acceso Abierto Análisis comparativo del comportamiento y costos de los sistemas constructivos pórticos resistentes a momento y muros de corte en hormigón armado(Universidad Católica de Cuenca., 2018) Mora Cabrera, Juan Carlos; Gamón Torres, Roberto; 0302400783; ., .This degree work is based on a comparative analysis of the building systems walls and a moment resisting porch, considering drifts of floor, torsion and direct and indirect costs. This work has 5 chapters which are: In chapter I objectives, justification, methodology, hypothesis, art history and study generalities are presented, which are fundamental for its developing. In chapter II the design bases, regulations and to codes to use, the analysis of live and dead loads (weights) their combinations, the parameters used for the static equivalent analysis (design spectrum, basal cutting, vibration period, etc.) are described. In chapter III the building geometry is presented, an analysis and structural design of the reinforce concrete 6-stoty buildings were made using the wall and moment resisting porch systems was performed supporting on an equivalent static analysis applied according to the Ecuadorian Construction Rule NEC-15 and ACI 318-14 Code for the design of stairs, beams, columns, concrete slabs, section walls, footings. Using the Etabs software for simulation focusing on its structural behavior. On base of the results, the inelastic drift and the torsion system of constructive moment resisting porch was compared with construction system of section walls. On chapter IV on based of the results of design a costs study was developed, and applied to the type of structures, where the economic aspect was compared considering the direct and indirect costs and the others which come from the damages and reparation. In chapter V conclusions and recommendations are detailed, it emphasizes that the section wall system in comparison with the constructive moment resisting porch system provides the reduction of floor drift and torsion. Also, the section wall system has less cost by damages and reparation, but the cutting wall system has an increase of 2,43%, but this percentage is not relevant keeping in mind the security that provides. It is advisable continue comparing these structural systems using buildings with elevation variation and level, to use the section wall system in seismic zones with high acceleration.
