Model Analysis for Identifying the Load-Bearing Capacity and Fire Resistance of the Reinforced Concrete Column

Abstract

In this paper a new technical solution in construction industry is presented, that relates in particular to testing compressed reinforced concrete elements - the building’s columns - for strength, stability and fire resistance, using scaled models. The subject matter is increasing the informative value, visual clarity and depth of experimental research of columns, using an economical technique of designing the geometric and force similarity of the reinforced concrete column’s scaled model for analyzing load-bearing capacity: strength, stability and fire resistance. The technical result is to identify the reinforced concrete column’s actual operation and its stress state from the beginning of the test and up to the stage of destruction; to evaluate the reinforced concrete column’s limit state according to its load-bearing capacity and fire resistance; to develop the analytical model for calculating the actual fire resistance limit; to save the labor costs for manufacturing the scaled test model of the real structure.
