Does anyone know what seismic force resisting system would be knee braced wood columns (for patio covers, decks, trellises and so on) (ASCE/SEI 7-10).I need to get an R. Or shall I just use lowest R=1.25 and I'll be safe ?
Even in ASCE 7-05 wasn't clear about this system. Am I missing something ?
When calculating the embedment of friction piles one uses, vertical load, seismic load and creep. For iisolated pad footings we don't. If I'm designing a hand dug caisson (end bearing deep foundation) should I still include creep and seismic ? At which point a footing becomes a caisson (from a...
