pretty sure that he said - 1 column failed near the pool due to poor
construction and poor design - that took out 2 beams that ruined 2
connections in the wall - the wall then went down taking the whole bld
down
we look at the situation this way - picture the bld as a house of
cards - and some of the cards are overstressed because they are
oriented wrong - and the connections between the cards are weak - and
then some of the cards get wet - it should not come as a surprise that
a failure of one column gets spread throughout the entire bld - unless
you specifically design the bld such that the failure of one column
will NOT bring down the entire bld
I imagine that you would have to make the structural members and their
connections very strong to resist a collapse or large impact load
