Abstract
A comparison between two models of buildings with the same architectural characteristics is presented to evaluate the economic advantages which are obtained by using a system of postensioned slabs, under all provisions and requirements that are established in the different codes and construction standards (ACI 318-14, NEC 2015 & PTI). The building to be compared is composed as a dual system of special moment frame in combination with special structural walls that together conforms the lateral force resistant system.
Also, the economic comparison was made for insulated reinforced concrete slabs and a typical plant with different spans showing graphically through curves and bars the savings in material quantities that can be achieved through the use of the post-tensioned system, thus showing an efficient and economical alternative for its application in the construction industry.
