Experiment and Simulation Verification on the Composite Mode of Enhanced Glulam

Abstract

The structural glulam used in bridge engineering is huge, which exists many defects by full-scale experimental method to research its relevant properties. Both experiment and simulation verification of ABAQUS were carried to forecast the enhanced composite structure and to reveal the composite enhancement effect of glulam made up of plantation eucalyptus veneers with the reinforced materials of fiberglass mesh and aluminium foil, and the basic mechanical properties were viewed as the evaluation index. The results show that the simulation model is feasible and rational to be applied to choose the better composite mode, and the best enhanced composite structure of glulam is the central seven layers eucalyptus veneers with criss-cross assembling structure, the outer three layers eucalyptus veneers with parallel assembling structure and fiberglass mesh and aluminum foil interval distributed among every two veneers.
