Análisis de estado de la estructura existente del Centro de Investigación de la Vivienda – CIV y diseño estructural de la ampliación del muro de reacción e infraestructura del CIV

Abstract

The Housing Research Center (CIV for its acronym in Spanish) belongs to the National Polytechnic School (EPN for its acronym in Spanish), it is located in the city of Quito, and it is characterized in the country by the existence of a reaction system composed of a reaction slab and walls in shape of “L”.

The present investigation allowed to know the current state of the existing structure of CIV are basing the analysis of the structural elements on different regulations such as NEC-15, ASCE41-17 and ACI318s-14. Together computational software was used for its review, where the mechanical characteristics of the materials placed in the mathematical model were obtained through experimental tests based on the ASTM standard.

The results obtained show that the current capacity of the structure is bigger than the demand, additionally for the reaction system the maximum loads that can be assigned in different locations that are presented.

Based on the verification of the existing structure and with the static and modal spectral analysis, the design of the expansion of the reaction wall with a maximum capacity of 50 [t] and of the CIV infrastructure with an approximate area of 400 [m²] is proposed, that allow obtained the resulting structural plans, along with a referential budget.
