I was after some advice as to the minimum practical width for precast wall panels. The walls are to be used internally in residential type construction and will only be subject to minor loading (approx 150kN/m). As the walls are only about 2.7m high I was expecting the connections to govern the wall thickness. I was intending to have two 20dia pins at each end of the 3m panels grouted inside 60dia corrugated conduits cast-into the panels. As such I was expecting the minimum panel width to be based on 55 + 2 x (20 cover + 12mm bar + 10 cover to conduit) + 10 tolerance = 150mm.
Is this a standard approach? Are trimmer bars required past the face of the conduits? Is any cover required between the conduit and the trimmer?
Assuming that the trimmers do not require cover to the conduit this could potentially be reduced to 55 + 2 x (20 + 12) = 120mm which still provides adequate axial capacity. This seems very skinny to me and I am sure erection requirements would not permit this.
Some guidance as to common practice for lightly load panel thickness and connection would be much appreciated!
Thanks!
