Increased strength of laminated bamboo beams using a shear connector adhesive method

Abstract

At this time the timber with good quality has been difficult to obtain, so the wood is increasingly rare for building construction. To reduce deforestation due to logging for construction materials, it is time to replace wood with bamboo. Laminated bamboo is an engineering building material that has a character like wood. Laminated bamboo structures can encourage the replacement of wood, steel and concrete materials so that the development of laminated bamboo technology can revolutionize the use of bamboo in construction. One of the weaknesses of the laminated bamboo beam structure is the adhesive line between the bamboo lamina. Mechanical lamination using a shear connector prevents horizontal slip between the bamboo lamina. Incising method is a method that makes the adhesive as well as the adhesive as well as the shear connector. Dendrocalamus asper research material with an average age of 4 years. The testing shear strength and tensile strength of bamboo block lamination was carried out based on ASTM D143 (2002). Experimental testing of flexural strength of laminated bamboo beams is carried out using a tool with a Multi Purpose Testing System and data logger. Changes in the structure of bamboo that are applied to lateral pressure are observed using SEM (Scaning Electron Microscopy). The use of Incising method in making laminated bamboo beams can significantly increase the strength of mechanical properties laminated beam structures.
