Practical Engineering: Deck Support Making the Crucial Connections

“It looked like a battlefield,” shouted the headline of the Atlanta Journal and Constitution for April 9, 1995. There was no field of combat involved, however. The scene of this eye-catching story was the backyard of a prominent Atlanta citizen in a well-to-do neighborhood: His deck had collapsed during a party, with 63 people on top. Sixty-three people may seem like a lot, but some easy calculations show that the load on the deck was no more than the building codes say a deck should safely support.
