摘要

摘要: 针对我国目前因在设计混凝土结构D区时尚无完善的理论依据,进而造成了很多混凝土D区开裂等工程问题,引入拉-压杆理论进行混凝土D区的配筋设计,提出拉-压杆模型的选取原则,并以一深梁为例按照拉-压杆理论进行了设计,总结出拉-压杆理论的设计步骤,可为类似工程提供参考。

Abstract: For there is no perfect design theory for concrete structure disturbed field to apply,a lot of concrete disturbed field crack accidents were produced.So STM (strut-and-tie method) is proposed to be used for the design of concrete disturbed field.The selecting principle of STM is proposed.A deep beam was designed based on STM and designing steps were summarized.It can be referenced for similar projects.
