摘要
介绍了对拉-压杆模型的设计方法及过程。拉-压杆模型受力过程简单,它以桁架结构作为计算体系且满足塑性下限定理,因此,是一种安全合理的混凝土设计模型,但我国目前对拉-压杆模型还缺乏理论研究和试验。
Strut-and-tie models （ STM ） design methodology and its realization are introduced.Strut-and-Tie Model has an advance in its simple mechanical model.The computation of STM is based on truss structure model that meets the low limit plastic theorem.Therefore STM is a design method which tends to be safer than the traditional ones, and also to be a rational design method for the reinforced concrete structures.However, very few studies have been conducted for evaluation of the STM either theoretically or experimentally.
