This deck collapse in Indiana injured many people and sent 7 to the hospital. It had a faulty construction, the beam was not placed above the post. It appears to have been attached to the post themselves
If you watch the video you can see the beam breaks and falls and the post remain standing. This clearly indicates that the posts did not fit under the beam and were somehow mechanically attached. This tragedy could be in so much worse this family is really lucky not to have had a fatality. Many are not that lucky when decks collapse.
