1Check Bearing Load of ScaffoldingDesign Assumption
1-1Take Section as following to consider :
To calculate maximum bearing load of a leg:DL = ton/m3 m3 = ton/m
LL1 = ton/m2 m2 = ton/mLL2 = ton/m2 m2 = ton/m
ton/m
Maximum bearing load of a leg = ton/m
Referring to test report of a tower -------------Appendix Use May 17,2013 material testing report sheet------ ton
Assume the Safety Factor is 2.5/ =/ =
Allowable bearing load of a leg = 7.48 tonCheck bearing load of scaffolding
