Please I want explain some attachment ..I put ? As not understand like 2(s2t/4g) From where 2 and why s2
Calculate other critical path Example 6.8 (McKenzie, 2003) Plate with Staggered Holes and Single and Double Angle Sections Determine the tension capacity of the plate and the angle sections shown in Figures 6.20(a), (b) and (o), considering the strength of the sections only (i.e. ignoring block shear and bolt strength). 50 mm , 50 mm , 50 mm 50mm 160 mm x 8 mm thick plate S275, 20 mm diameter bolts 2 28 UNIVERSITY OF BURAIMI (a) Plate with staggered holes
Explanation / Answer
Along with a diagonal bolt line, there is a combination of direct tensile stress and shear stress and thus a somewhat smaller area should.
To account this, the area to be deducted is the sum of the sectional area of all holes in a chain of lines ( zig-zag) extending progressively across the member, less s2 t/4g for each line extending between holes at other than right angles to the direction of stress.
In the path 1-2-5-3-4, there are two inclined lines so 2 is used.
