| 摘 要： | 根据FRP筋混凝土双向板的弯曲破坏特征,引入FRP筋名义屈服强度和FRP筋有效截面面积的概念,对板中局部均布荷载作用下的FRP筋混凝土双向板的受弯承载力进行了塑性极限分析,提出了FRP筋混凝土双向板极限受弯承载力的理论计算公式.建议公式与试验结果符合较好,可为FRP筋混凝土双向板的设计应用提供必要的理论分析依据.

| Abstract: | Based on the bending failure characteristic of concrete two-way slab reinforced with FRP rebars,the concept of nominal yield strength and effective cross-sectional area of FRP bars are defined,and the theoretical formula for calculating the ultimate flexural capacity of FRP rebar reinforced concrete two-way slabs by means of plastic ultimate analysis method are proposed.The theoretical formula proposed in this paper correspond with experimental results,which can provide the necessary theoretical basis for t... |
