The influence of continuing reinforcement on the load capacity of a RC beam previously exposed to high temperatures

Abstract

The paper describes the RC beam model development and the influence exerted by the main longitudinal reinforcement overlapping and transverse reinforcement (ties) on the bearing capacity of a RC load bearing structure for several cases of load, with an emphasis on the influence of high temperatures. Several RC beam models are made and relevant calculations and results are presented, which show the influence of the reinforcement method on the bearing capacity of structures, i.e. of the main-reinforcement continuing as related to the one-part reinforcement, as well as the influence of transverse reinforcement (ties).
