Structural Reliability Studies on Pulverized Glass Powder Concrete Subjected to Bending Forces with Natural Aggregate

The shortage of housing and basic infrastructure in Nigeria is assuming increasing dimension with continuous rise in the price of construction materials. Cement is a major component in concrete production, its production however is accompanied by huge carbon dioxide emissions. This research presents the results of structural reliability analysis conducted on reinforced concrete beam subjected to bending forces produced with pulverized glass powder as partial replacement for cement with Natural aggregate (NA) as coarse aggregate. First order reliability method (FORM) was employed to determine the level of safety of the beam. The result of the sensitivity analysis showed that the pulverized glass powder beam with NA as coarse aggregate is structurally safe at a span of 3000 mm and depth of 600 mm with probabilities of failure of 1.00 × 10-3 and 1.04 × 10-3 respectively.
