I'm building a 6.5m x 4.5m x 3.2m high summerhouse/garden shed. It has a steel structure comprised of two portal frames and some cross members. All the steels are mitred 152 x 89 UB 16s, off of 200 x 200 x 12mm thk base plates.
I want to avoid the use of apex/knee braces and instead provide apex/haunch brackets. Is there a rule-of-thumb for sizing/designing these elements?
