Question:

Scaffolding by probability limit state design of what the expression

Scaffolding by probability limit state design of what the expression

Answer:

With a strip of steel made of each layer of about 10 or more steel bars, when the building rises, in the top plus a few layers of steel can be added. It is the use of triangular ingots, and it also needs to pull the cables around to keep the balance, just like the country's poles.
The calculation of the strength of components, stability and connection strength, the load should be used in the basic combination of design values Permanent load factor should take 1 variable load factor should take 14 scaffold in the bending component, should still be based on the normal use of the limits of the state requirements of deformation Check the deformation of the components, the load should be used in the standard combination of design values, all kinds of load factor should be taken 10 when the vertical or horizontal horizontal axis of the axis of the opposite axis of the eccentricity of not more than 55mm, the pole The effect of this eccentricity is not taken into account in the stability calculation when the use of "construction fastener steel scaffold safety technical specifications" Article 611 of the structural size, the corresponding bar can no longer design calculations But even wall pieces, pole foundation bearing capacity should be based on the actual load design calculation the strength of steel design value and elastic modulus should be "construction of fastener steel scaffold safety technical specifications" Table 516 use fasteners, base, adjustable support bearing capacity design value should be "construction construction fastener steel scaffold safety technical specifications" Table 517 used 8 The deflection of the bending member shall not exceed the allowable value specified in Table 518 of the Technical Code for Safety of Fasteners for Construction Fastener Steel Scaffolding 9 The slenderness ratio of the compression and tension members shall not exceed the permissible values ??specified in Table 519 of the Technical Code for Safety of Fasteners for Construction Fastener Steel Scaffolding
2.1.23 step distance liftheight the distance between the upper and lower horizontal axis. (Commonly speaking is the high level, non-building level, but the height of each layer of scaffolding) 2.1.24 vertical vertical (cross) from the longitudinal spacingofuprighttube scaffolding vertical distance between the vertical axis. The (Generally speaking is the distance between the vertical pole and the pole, according to the specifications are 1.5m) 2.1.25 pole horizontal distance transversespacingofuprighttube scaffolding horizontal distance between the adjacent pole, single row of scaffolding for the external pole The distance from the axis to the wall. (Double row of scaffolding is the inner row (near the wall of the row of pole) and the distance between the row of poles, generally 800mm)
