谈钢筋混凝土箱梁顶板横向受力有效分布宽度的塑性

Plastic discussion on effective distribution width of transverse force of reinforced concrete box girder roof

结合极限平衡法对钢筋混凝土箱梁顶板塑性横向受力有效分布宽度和极限承载力的实验结果,具体介绍了钢筋混凝土箱梁顶板横向受力有效分布宽度的塑性内容,同时对《公路钢筋混凝土及预应力混凝土桥涵设计规则》所提出的弹性原理进行分析和探究,探讨了塑性有效分布宽度的问题,并提出如何有效的控制塑性有效分布宽度,以此来为之后的研究过程提供一个具体可操作的角度。

Based on the experimental results of the limit equilibrium method for the effective distribution width and ultimate bearing capacity of the plastic lateral stress of the reinforced concrete box girder,the plastic content of the effective distribution width of the lateral stress distribution of the roof of the reinforced concrete box girder is introduced,and the Design Rules of the Concrete and Prestressed Concrete Bridge and Culvert of the Highway Reinforcement are also introduced. The elastic principle proposed in this paper is analyzed and explored,and the problem of the plastic effective distribution width is discussed,and how to effectively control the effective plastic distribution width is proposed. In order to provide a specific and operational perspective for the subsequent research process,we hope to play a valuable role.
