Ultimate Capacity of Timber Joints.
Aim:
To determine the ultimate capacity of nailed and bolted connections and the modes at which they fail. The experimental results will be compared to the estimates predicted using AS 1720 - 1998.
Equipment:
Timber member (with nails or bolts connection)
Scale
Ruler
Loading frame
3 Dial gauge
Electronic readout
Load cell
Method:

…showed last 75 words of 3508 total…kNm) and bolts (5.23 kNm). Therefore the connections are weaker than the member.
Overall the experiment was a success in demonstrating the ultimate capacity of nailed and bolted connections and the modes at which they fail. The nail joint was far greater than that of the bolt joint, this was shown as the joint did not completely fail underload but instead moved away from the loading frame. The bolt connection on the other hand eventually failed.
