Análisis en laboratorio de los efectos en la resistencia a compresión y tracción de elementos estructurales de hormigón armado post afectación por altas temperaturas

Abstract

This study was focused on obtaining, through laboratory experimentation, the damage of compressive and tensile strength of reinforced concrete columns due to exposure to high temperatures in a laboratory oven based on the ISO 834 standard. The analysis was carried out with temperatures of 300°C, 600°C, 900°C, and extrapolation at 1200°C, for durations of one, two, and three hours in each case. The following elements were tested with those temperatures and times: complete columns of reinforced concrete, simple concrete cores and reinforcing steel rods extracted from columns.
