摘要

摘要: 为了验证耐候冷弯型钢应用于转角塔的安全性,以安徽某设计有限公司设计的220 kV电压等级的SJ2-18型转角塔为例,展开耐候冷弯型钢转角塔真型试验研究。采用耐候冷弯型钢制造的SJ2-18型转角塔通过了8个工况的100%设计载荷测试,当荷载达到140%时,转角塔支腿与塔脚连接螺栓发生剪切破坏。结果表明:SJ2-18型转角塔结构设计合理,强度安全可靠,能够满足DL/T 5154—2012《架空输电线路杆塔结构设计技术规定》的要求。研究结论为耐候冷弯型钢在转角塔中的应用提供了试验依据,对耐候冷弯型钢转角塔的推广提供了技术支持。

Abstract: Taking a SJ2-18 deviation angle tower with 220 kV voltage level designed by a design company in Anhui as an example, the research on full-scale test of the tower was carried out to verify the safety of weather-resistant cold-formed steel applied to deviation angle towers. The SJ2-18 deviation angle tower made of weather-resistant cold-formed steel passed the 100% design load test under 8 working conditions. The shear failure of the connecting bolts between the SJ2-18 leg and the SJ2-18 foot occurred when the load reached 140%. The test results showed that the structure design of the SJ2-18 deviation angle tower was reasonable, with safe and reliable strength which could meet the requirements of DL/T 5154-2012. The research results could provide an experimental basis for the application of weather-resistant cold-formed steel deviation angle towers, and provide technical support for the promotion of weather-resistant cold-formed steel deviation angle towers.
