This paper presents the reliability assessment of a reinforced concrete column subjected to Axial loading.
Locally available natural aggregate (NA) was used in concrete production, the results of preliminary tests
revealed the aggregate was adequate for concrete production. A typical column cross section of 230 × 240 ×
3000mm was adopted and probabilistically assessed. First Order Reliability Method (FORM) was employed to
estimate the implied probabilities of failures. The results of the sensitivity analysis showed that the reinforced
concrete column is structurally safe at length, breadth and depth of 3200, 240 and 230 mm with Probability of
Failures of 1.14 ×10-3, 8.45 × 10-4and 8.45 × 10-4 respectively.
