snow load case study
i live in western pa.  most of the area where i design is designated as a case study snow load area (cs) in ibc 2000.  does anyone know where case studies can be obtained?  i found a few web sites that had dead links and have tried to call the army corps but i haven't been able to find anything helpful.  some of the local code officials have their personal requirements, while others don't have a clue what the snow load should be in their area. any advice or links to information would be appreciated.
