Bending Behavior of Splice Connection for Mengkulang Glued Laminated Timber Beam

Abstract

This paper presents the experimental bending strength of steel dowelled splice glulam timber made of 'Mengkulang' species. Bending tests were conducted under a four-point bending load. Six (6) glulam specimens with 45mm x 90mm x 1800mm were loaded. Three (3) specimens were full beams as the control and three (3) splice beams dowelled with grade 8.8; 20 mm diameter steel rod. The embedded length of the steel dowel was 60mm and glued at 2mm thickness on both sides. Results show that the bending strength of the glulam control beam performed 74.18% higher than the splice beams with an increment of 58.26% displacement.
