摘要:
海洋环境下的导管架平台易发生腐蚀而导致承载力下降。为了提高含有腐蚀缺陷的导管架平台的承载力,提出了采用碳纤维增强聚合物(CFRP)加固含腐蚀缺陷YY型管节点技术。通过试验测试与有限元模拟相结合的方法,对CFRP加固含腐蚀缺陷的YY型管节点在支管轴向压力作用下的静力性能进行了研究,分析了未加固节点和经CFRP加固节点在破坏模式、变形、等效屈服应力和承载力等方面的差异,详细研究了节点试件的失效机理和过程。研究结果表明,经CFRP加固后YY型管节点的极限承载力提升了40.9%,CFRP加固方法能有效延缓管节点失圆率,缓解节点部位的应力集中现象; 加固节点失效时的塑性区域显著降低,CFRP约束主管变形是提高YY型管节点承载力的主要原因。本文研究结果为工程中CFRP加固导管架平台技术的推广应用提供了参考依据。
Abstract:
Jacket platforms in the marine environment are susceptible to corrosion and the further load-bearing capacity reduction. In order to improve the load-bearing capacity of the jacket platform with corrosion defects, this paper proposes a technology of applying the carbon fiber reinforced polymer(CFRP)to strengthen the YY-type tubular joint with corrosion defects. Through the combination of experimental testing and finite element simulation, the static behavior of CFRP-reinforced YY-type tubular joints with corrosion defects under the axial pressure of branch pipes has been studied, the differences on the failure modes, deformation, equivalent yield stress, load-bearing capacity, etc., of the unreinforced joints and CFRP-reinforced joints have been analyzed, and the failure mechanisms and processes of joint specimens have been studied in detail. The research results show that the ultimate load-bearing capacity of CFRP-reinforced YY-type tubular joints has been increased by 40.9%. The CFRP reinforcement method can effectively delay the out-of-round rate of tubular joints and alleviate the stress concentration at the joints; the plastic area when the reinforced joints are failed is significantly reduced, and the deformation of CFRP constraint main pipe is the main reason for the load-bearing improvement of YY tubular joints. The research results in this paper can provide a reference for the popularization and application of CFRP reinforced jacket platform technology in engineering.
