HOW TO USE MONOGRAMS:Select slab thickness, and project line upwards.Select applied load to be transferred across joint, and project horizontal line across both graphs.Where line 2 crosses preferred dowel deflection curve, project line downwards to determine predicted deflection.

NOTES:1. Design Loads [φV] include φ = 0.6 for fixings in accordance with AS 3600 Table 2.3.(j) for loads controlled by concrete; or φ = 0.9 in accordance with AS 4100 Table 3.4 for loads controlled by steel strength.2. Data for 20 mm Square Dowels and 6 mm Diamond Dowels is based on testing. Data for 10 mm Diamond Dowels is approximated.3. Design Loads apply to concrete strength at dowel for that particular slab thickness. 4. DO NOT USE THESE MONOGRAMS FOR SLAB DESIGN.5. Deflection characteristics are based on dowel properties and are not influenced by slab thickness, concrete strength or dowel spacing.6.

High performance dowel systems

ResearchFinite-element analysis of one half of a loaded Diamond Dowel indicates that the maximum stresses are located at approximately 1/6th of the depth of embedment.

A Queensland University of Technology research program on different dowel systems, funded by Danley Construction Products, confirmed the efficiency of Diamond Dowels compared to other systems. Over 90 test blocks 1m square x 150 mm thick were cast with round, square, plate and Diamond dowels. Each test block was instrumented to record load and deflection before being loaded to failure.

The research determined that Diamond Dowels have very efficient load carrying capacity and are superior in minimising differential deformation when compared to other dowel systems.

Based on these observations, it follows that Diamond Dowels can be used at wider centres than other dowels to transfer the same loads, thereby reducing dowel joint costs.
