I bought 100 tons of scaffolding steel pipe, according to the 150 tons of rack pipe to prepare various kinds of fasteners and fastening screws. How to calculate.. Thank you all
0.7 - the basic wind pressure reduction coefficient determined by the return period of 5 years. In some special cases, a value above 0.7 may be used, but not less than this value.More than W0, Z, beta Z, STW are in accordance with the "building structure load code" (GBJ9-87) of the corresponding provisions of the selection or calculation to determine, which STW 6.3.1 in accordance with its table thirty-second and thirty-sixth.
When the axial force and bending moment of the corresponding substitution effect of general practical design expression in S, can be calculated using the design (see below). Generally, the effect of load calculation is used in the calculation formula, that is, there is no load partial factor in the formula.
For the convenience of calculation, the working group can according to the corresponding standard scaffolding scaffolding load, the statistics range and ETA lambda value, compiles "m table for the reader to use
