Structural performance on beam with diferent size and spacing of link

Abstract

This report conducted the experimental studies to know the performance on beam with different size and spacing of link. The objective of this research is to design beam and reinforcement required for beam using British Standard, to determine the flexural strength of the beam with different arrangement and size of reinforcement and to identify crack pattern between different arrangement and size of reinforcement on beam. Slump test and flexural test had been carried out in order to investigate the workability, strength and crack pattern of reinforced concrete beam. Four samples will be test which is 2 samples B6 containing link size 6 mm spacing 150 mm and 2 sample B8 containing link size 8 mm spacing 200 mm. The fresh concrete mixture will be taken for the slump test. Then, the concrete will be pour into 1500 mm x 300 mm x 150 mm formwork. After 28 days, the harden beam will be tested. This experiment have shown that reinforced concrete beam with different size and spacing of link show considerable flexural strength increase for reinforced concrete beam with link size 8 mm spacing 200 mm compare to reinforced concrete beam with link size 6 mm spacing 150 mm. In all cases considerable strength enhancement and crack pattern has been observed. Thus it can be concluded that reinforced concrete beam with link size 8 mm spacing 200 mm are more stronger and had more strengthen the reinforced concrete beam with link size 6 mm spacing 150 mm.
