Description

The project focuses on the strengthening of structural elements, specifically a column in a building being transformed from its current P+1 structure, used for residential purposes, into a new P+2 structure intended to serve as a bookstore and storage space. The analysis begins with the assessment of the current structure in two key aspects: the capacity of the existing column dimensions to accommodate new loads (ductility factor) and the verification of the concrete class through non-destructive testing. After completing the inspection of the current structure, two options are proposed for the central column of the building: concrete retrofitting by increasing the column dimensions using higher-class concrete and a second method applying steel jacketing. Both methods are calculated based on the empirical formulas of EUROCODE 8, and the procedures for applying concrete column retrofitting and steel jacketing are explained in detail. After describing the procedures, the two methods are compared, focusing on the increase in actual dimensions relative to the space occupied by the new column, thus highlighting its impact on the overall structure
