Accoring to REIDsteel, a wordwide structural engineering company who specialise in designing and creating stadiums and multi-storey car parks as well as earthquake proof buildings, the roof of such a building must be as light as possible. This can be done with profiled steel cladding together with a layer of added insulation. It’s also important that the floors of the building are made as light weight as possible. This means that its light, flexible structure is able to absorb and, if necessary, even bend with the impact, preventing the building from being damaged.
