Assessment of dynamic loads

[Kiri Robbie]

Any comments on assessment of dynamic loads and protection from unexpected loads such as temporary storage of equipment and materials on the temporary works structure?

[Barnabas Ilko]

I am a little bit confused by the unexpected loads such as temporary storage comment.

I assume the question might be related to impact loading on structures from vehicular traffic, load being dropped from floors above if no protection fans are installed below, loads dislodging while lifting with tower crane. Or a usual item we debate which is loading on overhead protections from vertical and lateral loads.

In case you are after loads falling on a temporary structure, AS1170.1 should be used as a first step. The commentary will explain how to calculate these forces, simple physics. 

In case you are after storage and impact loads on falsework, please refer to the Concrete Institute of Australia's practice note Z36 which has a very good explanation of how these loads should be calculated.
