Experimental performance of threaded steel glued into laminated bamboo

A review on mechanical behavior of laminated bamboo lumber connections

“…Yan et al [118] carried out both-ends pullout test on GIROD-LBL (Fig. 21) according to ASTM D1761-88 [119], 8 samples were adopted for each group corresponding to rod diameter (8, 12 am 16 mm) and rod embedded depth (40,80,120 and 160 mm). The specimens showed 2 failure modes, which were threaded rod rupture and adhesive interface failure.…”

Performance of glued-in-rod connections in cross-laminated timber

“…Elsewhere [57], the optimum edge distance of 3.5d was identified as the distance with greatly reduced splitting failure and maintained strength. The edge distances were evaluated in [67] and it was recommended that greater than 3d should be used to prevent splitting failure of timber.…”

“…Although some studies [54,67,68] have pointed out that there's no proportionality between an increase in glueline thickness and higher load capacity, the glueline thickness can have a significant effect on connection failure mode [67]. The influence of the glueline is largely dependent on the adhesive properties [56].…”

“…A larger glueline thickness increases the contact area but does not significantly increase strength [43]. A thickness of 2 mm was recommended by [48,67].…”

“…To avoid splitting failure, in accordance to the recommendations of previous work [13,54,67] that the minimum edge distance of at least 3d should be used to avoid this failure, the edge distance (ed ≥ 4d) was used. In Phase 3, 8 test series with 5 replicates per series for a total of 40 specimens were tested.…”
