Description

Technical Field

[0001] The invention relates to the technical field of steel tube tower structure design, in particular to a design and verification method for ring plates at nodes between diagonal materials of steel tube tower legs and main materials of a tower body. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] At present, in the design and control of steel tube towers, there are relevant calculation methods for the equivalent forces between the main materials and diagonal materials of the tower body, the main materials of the upper and lower planes of the crossarms and the main materials of the tower body, the nodes of the cross diagonal materials, and the ring plates. However, there is no relevant calculation method for the equivalent forces between the nodes of the tower leg diagonal materials and the main materials of the tower body, and the ring plates. In addition, some standards or specifications do not consider the effect of the internal force of the tower leg diagonal materials on the eccentric bending moment generated by the node system, so there are certain errors in the design and verification of the ring plate dimensions.

[0004] In addition, the node between the tower leg diagonal material and the tower body main material is different from other common nodes on the steel tube tower. Because the stiffness of its lower ring plate (stepping plate) and the upper ring plate is quite different, the distribution of tensile pressure is different from that at other nodes. Therefore, the calculation method of other common nodes is not applicable to the node between the tower leg diagonal material and the tower body main material. Summary of the Invention

[0057] According to the bending moment, tension and compression, approximate stiffness ratio and vertical node plate size, the equivalent force design value of the ring plate is obtained, and the design size of the ring plate is verified according to the equivalent force design value of the ring plate.

[0058] like Figure 2 As shown, the steel tube tower includes a tower body main material and tower leg diagonal materials, and a vertical node plate, an upper ring plate and a lower ring plate are provided at the nodes of the tower body main material and the tower leg diagonal materials;

[0077] In this embodiment, the bending moment M and the tensile and compressive forces P are borne by the upper and lower ring plates. The equivalent force design value of the ring plate is obtained based on the bending moment M, the tensile and compressive forces P, the approximate stiffness ratio K, and the vertical node plate length B.
