Abstract

An experimental programme is presented that investigates the application of glued-in rods as moment connections in a post and beam connection. Nine partial portal frames were constructed of box sections with a beam depth of 600mm. The box sections were constructed of sawn timber flanges with orientated strand board and birch plywood webs. 12mm diameter basalt fibre reinforced polymer rods were used to connect the elements with a constant embedded length of 23·dr (280mm) and glueline thickness of 0.125·dr (2mm). Specimens with 2 no. and 3 no. rods were tested to structural failure. Specimens constructed from box sections with OSB webs reached their maximum capacity and then failed via elemental failure prior to the capacity of the connection being reached. Specimens with plywood webs were considerably stronger exhibiting failure in the connection. All the test specimens did exhibit significant deflection which would result in a lower serviceability limit state failure.
