Original Abstract

The paper focuses on the assessment of structures using the methods described in the new edition of the ČSN EN 1371 standard. An experiment will be conducted on cores taken from reinforced concrete columns under compressive loading up to the ultimate resistance. The concrete used to make the column should correspond to old concrete used in the second half of the 20th century. The column will be made with a deliberately created defect - such as stratification or bad compaction of the concrete. When the column is damaged, different degrees of damage to the concrete along its height occur. This can be detected by a thorough examination of cores through the ultrasonic and resonance methods.

Keywords
