RE: Chicago porch failure

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Martin:

It appeared from the photos that the ledger wasn't adequately anchored to
the
rear masonry wall...no expansion or epoxy anchors/bolts, probably just
masonry nails.

Also, it looks like the beam/column joint at the post was simply nailed,
not thru bolted or with connection hardware.

Does anyone have further information on the porch failure in Chicago this
weekend killing 12 and injuring 50+ people?  Did it fail at the ledger?  In
shear or did it pull out?
