Numerical Model Validation for Mengkulang Glulam Timber Bolt Withdrawal Capacity

The adequacy of timber joints determines how much load it can sustain, commonly called load-carrying capacity. European Yield Model (EYM), also known as Johansen yield theory, has been widely adopted in the design for predicting In EC5, pulling out capacity is 'rope effect' and becomes one parameter that governs a dowel-type connection. Due to high cost preparing specimen, computer modelling always alternative measuring connections. However, results need be validated with experimental laboratory test before being extended different sizes materials fasteners. This study presents finite element method (FEM) numerical analysis validate performance timber's 12mm, 16mm, 20mm bolt withdrawal Abaqus 6.14.4 software package create four (4) FEM models consisting inserted into glulam block at insertion depth, parallel perpendicular grain direction. axially was subjected pull-out force while held position. mild steel tropical Mengkulang blocks were used. validation showed an acceptable agreement between results.
