The average weight limit for a standard balcony is 100 lbs per square foot. That balcony looks to be 8'x4' which would hold 3200 lbs. 16 people at 150 lbs each is 2400 lbs, which is quite conservative. I'd venture to say this was a situation where the weight limit was very close to being exceeded, with an added factor being that the weight load wasn't static, in that there were fluctuations due to movement (i.e. dancing, etc.). They'll be doing some stress tests/core samples to determine if the concrete used met code, or if the contractor which did the work cheated.

Very sad though. Poor kids were just trying to have a good time.
