Abstract

This research examines the behavior of Self Compacting Concrete beams reinforced withround hollow steel pipes on fc' 25 MPa concrete which aims to determine the effect of both types ofreinforcement characteristics on flexural capacity, deflection, and crack patterns in self-compactingconcrete beams reinforced with round hollow steel pipes size 1.8 x 16 x 1000 mm and plain steelreinforcement ∅10 which is used as longitudinal reinforcement. The specimen of a reinforced concretebeam with a dimension was 12 cm x 18 cm x 100 cm used 2 types of longitudinal reinforcement. BTHbeams use longitudinal reinforcement from round hollow pipe steel reinforcement measuring 1.8 x 16x 1000 mm and BTK beams use longitudinal reinforcement from steel reinforcement plain ∅10 whilethe stirrup reinforcement used steel reinforcement ∅6. Based on the research results, the averageflexural capacity of BTK beams is 16.50 MPa and the average flexural capacity of BTH beams is16.41 MPa. The test results of the maximum deflection of the BTK beam are 9.83 mm and the averagemaximum deflection of the BTH beam is 7.84 mm. The flexural capacity between the two types ofbeams does not have a significant difference. The maximum deflection that occurs from the BTKbeam and the BTH beam does not have a significant difference. The crack pattern of all beamspecimens is categorized as a flexural crack.
