Comparación económica al diseñar edificios de hormigón armado de 7 y 14 pisos, con la NEC-11 y el CEC-2000

Abstract

Considering that few years ago, Ecuadorian Construction Code (CEC-2000) has been studied to be modified and updated, a preliminary version in 2011 called Ecuadorian Construction Standard (NEC-11) was made; this version was finally approved with some modifications in 2015. It arises to compare the results obtained by applying the above two standards. For the analysis two heights of buildings were chosen: seven-story building and fourteen-story building. Each one has two alternative structural configuration, they are implanted in soil type S2 based on CEC and soil type C and D based on NEC. Buildings are designed according to earthquake-resistant philosophy presented in each one of the applied standards. Once designed the 12 alternative proposals, drawings volumes and quantities of materials required for each one of them are determined based on structural plans. Then, a unit price analysis is performed and the final cost for each structure is estimated. Finally, a comparison of structural behavior and economic variation that is the result of designing with reinforced concrete based on the current standard
