| 摘 要： | 由于FRP筋特殊的材料性能,导致其混凝土梁的挠度较大。在国外有关成果的基础上,给出了FRP筋混凝土梁的挠度计算建议方法及“有效惯性矩”的表达式,同时提出了设计时不需进行挠度验算的最大跨高比限值的计算公式及相应的基于挠度控制的承载力设计方法,对工程应用有着实际的指导作用。

| Abstract: | The special material characteristics of FRP bar lead to deflection of the concrete beam.Based on the research progress abroad,calculation method of deflection due to short-term loads and calculation expression of effective moment of inertia for concrete beams reinforced with FRP bars were brought forward.And calculation formula of the maximum limiting span/depth ration without checking deflection was presented.The method for designing bearing capacity based on deflection control was formed.The research provides convenience for engineering application. |
