I have always been instructed to us a 2 to 1 saftey factor when designing concrete footing/foundations to resist uplift. is this in any code (florida)?
i'm working on an existing condominium support by psl beams. the contractor originally going to replace all beams but now wants to test and hopefully only replace about half of beams. what, if any, test methods are available to determine if the psl beams are adequate. destructive and...
i have a psl beam spaning approx. 21 feet. the beam is 7 inch wide and 14 inch deep supporting a 2x4 wall and roof above. the wall is not centered on the beam. need to add a 1/2 inch x 14 inch flitch plate. how do i determine the number and spacing of bolts required?
