关于在多次重复荷截作用下鋼筋混凝土受挠杆件的法向断面的应力状态,目前尙缺乏明晰的介紹。按技术规范CH200-62和-B Ⅰ-62設算梁的耐久性时,混凝土受压区的应力图相应地采用三角形;同时又有矩形应力图的假定。这就是提出特别研究的原因,此項研究是在A.A.格渥茨捷夫教授領导下于苏联建筑科学院混凝土与鋼筋混凝土科学研究所鋼筋混凝土理論与新型鋼筋中央实驗
With regard to the stress state of the normal section of the reinforced concrete flexure member subjected to repeated loading and unloading, there is no clear introduction at present. When the durability of the beam is calculated according to the technical specifications CH200-62 and -B I-62, the stress map of the concrete compression zone is correspondingly triangular; at the same time, the assumption of a rectangular stress diagram is provided. This is the reason why a special study was put forward, under the leadership of A. A. Groovitz at the Institute of Concrete and Reinforced Concrete Science, Institute of Concrete and Reinforced Concrete, Central Institute of Reinforcement and Reinforced Concrete Research
