摘　　要：拉-压杆模型设计法因其力学概念清晰,设计计算简便,受到国内外广泛关注,欧美等技术发达国家先后将其纳入混凝土结构设计标准。我国新修订的JTG 3362—2018《公路钢筋混凝土及预应力混凝土桥涵设计规范》已将其正式引入。全面介绍拉-压杆模型的设计原理、建模原则、实施步骤与校验方法,并以一混凝土桥墩支座设计为例,对比中欧标准关于拉-压杆模型设计方法的异同点,以期对工程设计人员了解欧洲标准有所帮助。The strut-and-tie models design method has been widely concerned at home and abroad because of its clear concept of mechanics and simple design and calculation.Technically developed countries such as Europe and the United States have successively included it in the design standards of concrete structures.The newly revised"Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts"(JTG 3362-2018)has introduced it into the Appendix.In this paper,the design principle,modeling principle,implementation steps and verification method of the model are introduced comprehensively,and the similarities and differences of the design method of the strut-and-tie models between Chinese and European are compared with the whole process of the design of a concrete pier support,in order to help engineering designers to understand the European code.
