Cantilever scaffold setting

Your problem is bigger, and I don't have much time to help you. Now I copy a ready-made calculation scheme of cantilever scaffold for your reference:

1, the design value of the axial pressure of the vertical rod n =1.2×1.67+0.85×1.4× 0.84 = 3kn.

2. The bending moment of the vertical pole caused by the standard value of wind load: mwk = 0.16×1.2×1.752 ÷10 = 0.06kn.m.

3. The bending moment of vertical pole generated by the design value of wind load: MW = 0.85×1.4× 0.06 = 0.07 kn.m.

4. The axial force generated by the standard value of dead weight of members: NG2K = 0.42+0.17+1.08 =1.67 kn.

5, the stability of the stud calculation:

(1), the slenderness ratio of the vertical pole is calculated: where the calculated length of the vertical pole is l =1.155×1.5×1.75 = 3.03m.

I the radius of gyration of the vertical rod I =1.67cm.

After calculation, the slenderness ratio λ = 3.03×100 ÷1.67 =182.

(2) Calculation of the stability of the vertical pole: When the wind load is not considered: a The net cross-sectional area of the vertical pole is taken as A=4.43 cm2 N, which is the design value of the axial pressure of the vertical pole; Let N=3. 18 kN. According to the slenderness ratio λ look-up table, the stability coefficient of φ axial compression stud is obtained, φ=0.2 16.

When the wind load is not considered, the stability of the vertical pole σ = 3.18×1000 ÷ (0.216× (4.43×100)) = 33.23 n/mm2.

Considering the wind load, the stability of the vertical pole σ = 3×1000 ÷ (0.216× (4.43×100))+(0.07×100000) ÷ (4.

6, even the calculation of the wall:

(1), the design value of axial force of diaphragm wall caused by wind load is calculated according to the following formula: the design value of axial force of diaphragm wall caused by wind load NLW =1.4× 0.16×12.6 = 2.82kn.

(2) The calculated axial force of wall connectors shall be calculated according to the following formula: the calculated axial force of wall connectors.

Nl=2.82+5=7.82 kn

(3), even the wall axial force design value.

..... I can't send it.
