Re: Rink roof collapse in Germany

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Ice, and/or rain on snow / wet snow.  They list 8" on the roof, but 1.5 feet of "wet snow" measured (assumed) nearby.  IT also sounds as if they've had some freeze-thaw, but the wording that the potential survivors in the wreckage would have to endure temperatures dropping below freezing again tonight. Could just be a translation idosyncracy, though.

ASCE 7snow loads are based on 50 year snows. In my town, we've had a 80-100 year snow in the last 40 years, and I've had to design one building to a 100 year snow based on an owner request.  Also, 1.5' of snow is a pretty good roof load for a moderate climate.  If this building was designed anything like a PEMB, there's probably little margin in the roof loads for an exceptionally heavy snowfall.

Maybe some of the load was actually ice.

Apparently, there are differing stories about just how much snow had built-up on the roof of the ice rink.  Not having designed any structures for snow loading, shouldn't this roof have held up to 1.5ft of snow, considering it's location?  I'd be curious to hear others...;_ylt=ApLIh8rPogZ1NbPZflCNZces0NUE;_ylu=X3oDMTA3b3JuZGZhBHNlYwM3MjE-
