I have been asked to extend an existing 6' opening in a CMU wall to 12' width. The problem is there are NO drawings of any kind for the building. It is a 15 story block and plank construction hotel that is 36 years old. Verifying the CMU strength and reinforcing is relatively straight forward...
Deflection is related to curvature right? I need to calculate the deflection of a plated wood roof truss if the bottom chord splice slipped 1/8". Any ideas?
