✦ Synopsis
This paper presents an experimental programme conducted to investigate the structural capacity of bonded-in steel bars loaded parallel to the grain in standard straight elements of natural timber. Tensile pull-out tests were conducted to examine the effect of bar diameter, bonded length and bar type (deformed and threaded steel bars) on the structural capacity of the connection. Pull-out tests on timber blocks in which the bars were deliberately misaligned in the holes were also tested to account for the fact that in real situations bars may not be perfectly centralised in the holes. The pull-out test results showed that bar diameter, bonded length and bar type considerably affected the structural capacities of the bonded-in steel joints. The results were compared with some established design equations.
