Heavy concentrated dynamic load on slab
Heavy concentrated dynamic load on slab
(OP)
Good afternoon!
It is necessary to put car jacks on a composite slab. The slab is multi span and is over secondary steel beams spanning 1.7m.
The composite slab consists of a steel decking panel, and a reinforced concrete of 100 mm height counting from the top of the decking panel's rib.
Except from distributed loads, I have a concentrated load of 30 kN, which is also dynamic.
Do you think that it is possible to design such a slab?

Thank you,
Davit Sh

p.s.: I did not check you image thoroughly, so please consider my comment as "just a general guide".

Most of the testing to determine bond and slip resistance have been done assuming UDL loads which give a gradual change in stress and therefore bond requirements. Point loads will cause a much more severe change in bond requirements and may result in reduced boned and thus strength. You would need to make sure that the slip model you are using has considered this.

Also a note...i see you have 3 layers of rebar. Imho middle layer is unecessary.

Actually I removed it already. This type of slab is new to me. Thank you
