—Bolt-laminated bamboo beam was utilized as an alternative to replace wood and it was used as structural and non-structural construction material. Bamboo material then has become the most popular non-wood material in construction field. Nowadays, bamboo material is not optimally utilized yet. Many studies showed the advantages of bamboo to be compared to the other materials. The diameter of Gigantochloaatroviolacea bamboo used in this study is ranged from 70 to 90 mm. The diameter of bolt is 12.7 mm. The improvement of strength and bending stiffness of beam can be conducted by arranging the full-culm bamboo with bolt as the shear connector. Variations of bolt distance in this study were 125 mm, 250 mm and 500 mm. The final product of the bamboo jointed segment is bolt-laminated bamboo beam. Setup test for bolt-laminated bamboo bemuses four point bending method. The strength and bending stiffness of boltlaminated bamboo beam has increased as the bolt distance decreased.The shear connector distance that are greater than 500 mm has no significant affect to the strength and bending stiffness of the beam. Therefore, the distance of bolts is suggested to be less than 500 mm.
