Zemun tle:Inspection and Acceptance Criteria for Steel Trusses

is paper presents the inspection and acceptance criteria for Steel trusses. The inspection and acceptance criteria are based on the standards of the International Organization for Standardization (ISO) 1983, which is a standard for structural steelwork. The inspection and acceptance criteria include the following: 1) visual inspection of the surface of the steel trusses; 2) measurement of the dimensions of the steel trusses; 3) measurement of the weight of the steel trusses; 4) measurement of the thickness of the steel trusses; 5) measurement of the yield strength of the steel trusses; 6) measurement of the ultimate strength of the steel trusses; 7) measurement of the elongation of the steel trusses; 8) measurement of the hardness of the steel trusses; 9) measurement of the impact toughness of the steel trusses; 10) measurement of the fatigue life of the steel trusses; and 11) measurement of the corrosion resistance
