Problems solved by technology
This kind of structural system is sensitive to wind load, prone to vibration fatigue damage and dynamic collapse damage under extreme conditions (such as under the action of typhoon)
[0003] The cross-shaped overhead transmission tower designed and built in the past (four columns constitute the tower, and the side of the tower is a plurality of cross-shaped diagonal braces) has no secondary diagonal braces, and the wind load design value is relatively small in the design process , leading to poor wind resistance of this type of overhead transmission tower

Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing.
[0029] In the embodiment of the cross-shaped aerial transmission pole tower of the present invention, the pole tower includes four upright columns 2 constituting corner columns, and a plurality of groups of cross-shaped diagonal braces are arranged on the upper and lower sides of the pole tower, and each group of cross-shaped diagonal braces is composed of two diagonal braces 1 Composed of crossing, the upper and lower ends of the diagonal braces are respectively connected to the two columns 2 on the same side of the pole tower. On the side of the tower with weak structural characteristics found out from the structural analysis of the prior art and on-site measurement, in the triangular area formed between the diagonal brace 1 and the column 2, a circle with a diameter equal to the inscribed circle of the triangular area is provided. 70% of the circular energy dissipator, t...

A cross-shaped overhead power transmission tower, the tower includes four columns 2 constituting corner columns, multiple groups of cross-shaped diagonal braces are arranged on the upper and lower sides of the tower, and each group of cross-shaped diagonal braces is crossed by two diagonal braces 1 The upper and lower ends of the diagonal braces are respectively connected to two uprights 2 on the same side of the tower. In the triangular area formed between 1 and the column 2, there is an annular energy dissipator with a diameter of 70% of the inscribed circle of the triangular area, and the annular energy dissipator is connected to the The position of the point of tangency between the diagonal brace 1 and the column 2 and the inscribed circle. The invention can not only improve the overall rigidity and local bearing capacity of the structure of the overhead power transmission tower, but also dissipate a part of energy under the action of typhoon load, thereby improving the overall performance of the overhead power transmission tower.
Description
technical field [0001] The invention relates to a cross-shaped overhead power transmission tower provided with energy-consuming components. Background technique [0002] The overhead transmission pole-tower line system is the carrier of high-load electric energy transmission and an important lifeline engineering structure. The overhead transmission pole-tower line system has the characteristics of high tower structure, large span, and soft overall structure. This kind of structural system is sensitive to wind load, and is prone to vibration fatigue damage and dynamic collapse damage under extreme conditions (such as typhoon). [0003] The cross-shaped overhead transmission tower designed and built in the past (four columns constitute the tower, and the side of the tower is a plurality of cross-shaped diagonal braces) has no secondary diagonal braces, and the wind load design value is relatively small in the design process , resulting in poor wind resistance of this type of...
