摘要: 格构式复合材料塔采用了由钢制螺栓机械连接的D型复合材料管,其中复合材料管制孔和螺栓预紧力对杆件承载力影响还没有相关研究,其承载特性不太清楚。为准确掌握D型复合材料管的连接性能,通过D型复合材料管的塔节间模型节点试验,得到复合材料杆件连接孔端部以劈裂和剪切破坏为主;通过有限元模型分析了螺栓预紧力对D型复合材料管连接性能的影响,结果表明D型复合材料塔用抗剪螺栓的预紧扭矩宜控制为220 N?m。

Abstract: The D-shaped composite tube which is mechanically connected by steel bolts is applied to the lattice composite tower. However, there is still lack of enough studies on the impacts of machining hole and bolt pre-tightening force on the rod bearing capacity and the bearing properties are still unclear in the current field. In order to understand the connection performance of D-shaped composite tube, the node test on the inter-node model of the tower with D-shaped composite tube is carried out, which concludes that the damage type on top of the connection hole of the composite rod is mainly slipping off and shearing. Then, the analysis on the impact of bolt pre-tightening force on the connection performance of D-shaped composite tube is conducted with the finite element model. The analysis result indicates that the value of pre-tightening torque of the shear bolts for D-shaped composite tower should be 220 N?m.

Key words: D-type, composite tube, node test, pre-tightening torque, finite element analysis, bolt pre-tightening force
