Shear failure of the Meraka hardwood in bolted connections loaded parallel to the timber grain

This current study was conducted to establish a bolted connection experimental database on Malaysia woods. The effort of improving the retrofit guideline in designing wall-diaphragm connections masonry buildings can be continuously done. Brittle failure verifications Meraka hardwood verify occurrence row shear are presented this paper. species selected due its common use as structural rafters and joists construction roof floor diaphragms buildings, respectively. Ten groups single steel-wood-steel (SWS) loaded parallel timber grain were tested. Each group prepared with total ten replicates specimens. Comparisons strength between results predictions existing design equations discussed. It found that standard (MS544) too conservative estimating strength, whilst Row Shear Model (RSM) is more comparative.
