The steel beams, while not actually collapsing, were severely damaged, and access to the damaged area had to be restricted for safety reasons after the test.
A statement of the blindingly obvious - the structure of the Cardington building had not been compromised by being hit by an aircraft.
I note that in the material you quote the building is referred to as a "simulated, eight-story [sic] building". It wasn't "simulated", it was a full size eight storey building.
