Comportamiento estructural de edificios regulares utilizando losas alivianadas y postensadas

Abstract

Ecuador is located within the so-called Pacific Ring of Fire, so its seismic activity is high and it is exposed to recurring seismic events, to such an extent that these telluric movements are perceived with intensity in several provinces. Here the importance of the implementation of relatively new alternative methods that are consistent with the different needs and are adapted in the constructions of the country, to safeguard structural and human safety. Among the new structural technologies, the use of post-tensioning in slabs stands out. For this reason, this article aims to evaluate the structural behavior of regular buildings using lightened and post-tensioned slabs, in order to carry out a comparative analysis between the structural responses. For this, the study of four structural models subjected to a static analysis and spectral modal analysis was carried out. Based on the results obtained, they show that the implementation of post-tensioned slabs in regular buildings generates a 0.51% reduction in floor drifts by spectral modal analysis; a 2.04% and 7.52% reduction in the self-weight of the structure and a 15.28% reduction in the height between floors due to the absence of cambered beams, benefiting the structure with the implementation of two floors.
