Análisis comparativo estructural-económico según el código NEC2011 entre sistemas constructivos de muros portantes de hormigón armado con alma de poliestireno y muros de enchape con malla electrosoldada, en una estructura de 4 pisos.

Abstract

The present project describes, evaluates and compares the constructive system of a building of supporting walls with polystyrene core facing the same building with veneer walls using welded mesh. The premises described in the comparative process and its modeling begin with the same technical variables as four story high buildings, 2,52m between stories dimension and an approximate area of 225m2. The technical variables for the modeling of supporting walls with polystyrene core are a 2,5mm mesh every 6,5cm; while for the veneer walls was used a 4mm mesh every 15cm, with a 3cm mortar coating on each one of the faces of the wall. Using the same technical principles for the between stories slabs in the polystyrene core system, a 5cm thickness is established for compression and 3cm for traction, and for the veneer walls system a solid slab of 12cm high. Is possible to conclude in the study that the supporting walls with polystyrene core are lower costly, lower execution time and less structural weight, which allows to consider an applicable system for vulnerable zones in the social, economical and seismical areas of our country.
