Main Question or Discussion Point

Hi
In a demolition what is the horizontal thrust of the near buildings remain.?

that is for calculate the scaffolding to support the near buildings of a demolition.

I read somethingh of a 10 per cent of the dead weight of the walls of the building remain but I think is very conservative.

In theory, there is no lateral force, but a small perturbation can initiate a lateral force that is indeterminate, and, possibly, growing with displacement. In practice, codes of practice suggest conservative values based on experience. To complicate it further, there is a time-dependent element to this. Where I live, a building adjacent to a demolished and excavated site fell down. It took 40 minutes from first cracks appearing to total collapse, giving the occupants time to exit safely.
