摘要
提出了基于结构耐久性的叠合墩柱设计概念,将具有较高耐久性能的超高性能纤维改性混凝土永久模板应用于叠合墩柱结构设计,使得超高性能纤维改性混凝土模板成为新一代多功能永久模板,并详细阐述了该新型结构设计概念的工程背景.基于此,综述了超高性能纤维改性混凝土的基本材料性能和设计方法,介绍了超高性能叠合墩柱结构的设计方案.最后,展望了该类新型结构面临的需要解决的关键科学问题,并结合在研课题做了进展综述.
A conception of hybrid pier with consideration of structural durability was put forward in this paper. By applying the permanent formwork of ultra-high-performance fiber reinforced concrete with high durability to the design of hybrid pier, the formwork became advanced, permanent and multifunctional. The engineering background of this new structural conception was introduced in detail. On the basis of this theory, the material properties and design method of ultra-high-performance fiber reinforced concrete was summarized, and the design scheme of the ultra-hlgh-performance hybrid pier was described. Finally, the main scientific subjects in this new type structure were outlined and the progress based on the research project was summarized.
