Abstract :
This paper presents the flexural properties of rectangular Burma teak wood beam without finger joint and with finger joint. Finger joints enable full utilization of wood. Finger jointing technique is also used to eliminate wood defects which weaken the strength of wood. This paper considers finger joint as defined defect and its effect on the flexural strength is determined. Teakwood is hard and heavy, seasons rapidly and has good durability. The specimens were studied under three point bending test. Both edge wise and flat wise tests were carried out. It is observed that Burma teakwood beam without finger joint is stronger than beams with finger joints. Because of finger jointing the flexural strength reduces. It can be concluded that the strength loss can improved upon by selecting suitable geometry of finger joint and a suitable adhesive. It is recognized that further studies are necessary on jointing techniques of wood and type of adhesive so as to equal the flexural strength properties of clear teak wood beams.
