Abstract

Abstract. Laminated of Mahang and Meranti wood were the efforts to improve the
efficiency of hardwood (Meranti) and light wood (Mahang), so that to be used for
structural timber. Variant of connectors were expected to increase laminate beam
capacity compared to solid beams. Samples have been made include properties material
samples and laminated beam samples with dimension 76 x 5 x 5 cm. Beam sampleswere
3 types of connector i.e. glues, nails and bolts. The capacity was obtained by provided
one point load at the center of span. In addition to load force, deflection were also
recorded which then analyzed the flexural capacity, MOR and MOE. The result showed
that at the limit deflection, the glue laminated beam (BL LM) has a higher average
capacity than the bolt laminated beam (BT BL) and the nail laminated beam (BL PK).
In contrast, at the ultimate conditions, BL PK has a higher capacity rather than the
others. At the same time, BL LM has a higher average of MOE of 6818.88 MPa and
BL PK has average of MOR 3 times larger than Meranti solid beam (BL ME).
