Assessment of ultimate bearing capacity of RC sections affected by mineral oil

Bearing capacity of RC sections subjected to bending and eccentric compression and being under the influence of oil is evaluated. Two states of oiling up are considered: non-oiling up state and oiling up state after 12 months of subjecting the RC section to oil influence. Ultimate bearing capacity of reinforced sections influenced by mineral oils is evaluated numerically based on the diagrams of the limit state interaction. The analysis is carried out for rectangular section with tension and compression reinforcement. In the case of oiling up state, the bearing capacity of a section decreases compared with that being in non-oiling state.
