Industrialised Building Systems (IBS) involves offsite fabrication in a systematic and controlled environment. The aim of this research is to determine the structural performance of newly enhanced column corbel support for IBS industry application. However, there is no solid data to support the industry in producing safe and reliable IBS structure with newly enhanced prototype. Hence, the objectives of this research paper are to identify failure behaviour, flexural strength, maximum deflection and ductility of the IBS beam to column corbel connection. Scaled 1:5 IBS beams with column supports were prepared according to Buckingham and Similitude Theorem. Result contribution of five specimens were obtained from the flexural strength test. The scaled beam has maximum flexural resistance of 2.2 kNm and deflection of 7 mm. The projected flexural resistance for full scale beam is 1265.6 kNm with ultimate load deflection of 35 mm. Failure behaviours such as shear cracking, flexural cracking and concrete crushing have been identified. The average ductility of the specimen was 3.23 which is higher than 3.0 from PCI design handbook. The newly improved specimen has the load bearing improvement of 32%. Thus, this research has positive outcome that could improve the confident level of the industry user toward this product.
