on a 18mx12m building with 4m up rights and 2x1m concrete panels in 4.5m bays, how far underground are holding down bolts?
If they're at the surface or say 300mm below is that enough. Does the wall strength come from the rafters holding the top of each column together.
203x133x25UB Columns, which may seem light but with 2 extra posts in each bay behind panel.
