[0071] It should be noted that the load of this sky corridor is calculated according to the "Steel Structure Design Standard" GB50017-2017;

[0072] When the length of the sky corridor is 8m, the deadweight of the corridor assembly is 2152kg, the estimated load capacity is 4005kg, and the parameters of the steel structure connection interface are as described in Table 1 below:

[0073] Table 1: Steel structure connection interface parameters

[0074] 1. Basic parameters Connection Type Ordinary bolts, anchors, rivets Connecting components Ordinary bolts Number of shear surfaces of components 2 Rod diameter d(mm) 16 Effective diameter of the rod at the thread de (mm) 16 Minimum total thickness of pressure-bearing components in the same direction of force (mm) 10 Design value of shear strength of rod fv (N / mm2) 125 Design value of compressive strength of rod fc (N / mm2) 360 Design value of tensile strength of rod ft(N / mm2) 360 Shear force Nv (kN) borne by the member 5.03 Tension Nt (kN) on the rod 5.03

[0075] The load calculation of this sky corridor is as follows:

[0076] 1. When ordinary bolts are connected in shear, the design value of the bearing capacity of each ordinary bolt should be the smaller of the design value of shear and pressure bearing capacity.

[0077] The design value of shear bearing capacity shall be calculated as follows:

[0078] Nvb = nvπd2fvb / 4

[0079] Where d is the bolt rod diameter, take d = 16 mm;

[0080] nv – the number of sheared surfaces, take nv = 2;

[0081] fvb - the design value of the shear strength of the bolt, take fvb = 125 N / mm2;

[0082] Calculation: Nvb = 2×3.1415×162×125 / 4=50265.482 N;

[0083] The design value of the compressive bearing capacity shall be calculated as follows:

[0084] Ncb = d∑tfcb

[0085] Where d is the bolt rod diameter, take d = 16 mm;

[0086] ∑t - the minimum total thickness of the pressure-bearing member in the same force direction, take ∑t = 10 mm;

[0087] fcb - the design value of compressive strength of ordinary bolts, take fcb = 360 N / mm2;

[0088] Calculation: Ncb = 16×10×360=57600 N;

[0089] Therefore: The design value of the bearing capacity of ordinary bolts is 50265.482 N;

[0090] 2. When ordinary bolts are connected in tension in the axial direction of the rod, the design value of the bearing capacity of each ordinary bolt should be calculated as follows:

[0091] Ntb = πde2ftb / 4

[0092] The effective diameter of ordinary bolts or anchor bolts at the thread is de = 16 mm;

[0093] ftb - the design value of tensile strength of ordinary bolts, take ftb = 360 N / mm2;

[0094] Calculation: Ntb = 3.1415×162×360 / 4 = 72382.295 N;

[0095] 3. When ordinary bolts are connected by shear and tension at the same time, each ordinary bolt should be subjected to shear force and tension in the rod axis direction at the same time, which should meet the following requirements:

[0096] ((Nv / Nvb)2 + (Nt / Ntb)2)1 / 2 ≤ 1

[0097] Nv ≤ Ncb

[0098] Where Nv is the shear force borne by ordinary bolts, take Nv = 5.03 kN = 5.03 × 103 N;

[0099] Nt - the tensile force borne by ordinary bolts, take Nt = 5.03 kN = 5.03 × 103 N;

[0100] [(Nv / Nvb)2+(Nt / Ntb)2]1 / 2=[(5.03×103 / 50265.482)2+(5.03×103 / 72382.295)2]1 / 2 = 0.122 ≤ 1;

[0101] Nv = 5030 N ≤ Ncb = 57600 N;

[0102] Therefore, the bearing capacity verification of ordinary bolts can meet the requirements.

[0103] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the above disclosed technical contents without departing from the scope of the technical solution of the present invention.
