Abstract: The design of fiberreinforced polymer reinforced concrete FRPRC is typically governed by serviceability limit state requirements rather than ultimate limit state requirements as conventional reinforced concrete is. Thus, a method is needed that can predict the expected service load deflections of fiberreinforced polymer FRP reinforced members with a reasonably high degree of accuracy. Nine methods of deflection calculation, including methods used in ACI , and a proposed new formula in the next issue of this design guide, CSA S80602 and ISIS M0301, are pared to the experimental deflection of 197 beams and slabs tested by otherinvestigators. These members are reinforced with aramid FRP, glass FRP, or carbon FRP bars, have different reinforcement ratios, geometric and material properties. All members were tested under monotonically applied load in four point bending configuration. The objective of the analysis in this paper is to determine a method of deflection calculation for FRP RC members, which is the most suitable for serviceability criteria. The analysis revealed that both the modulus of elasticity of FRP and the relative reinforcement ratio play an important role in the accuracy of the formulas.CE Database subject headings: Concrete, reinforced。 =moment of inertia of the cracked section transformed to concrete。 M/EI=curvature of the section。本文分析的目的是確定FRPRC構(gòu)件撓度的計算方法,也是確定最適用的可靠性的準(zhǔn)則。除了優(yōu)越的耐用性,FRP鋼筋強度遠(yuǎn)高于傳統(tǒng)的低碳鋼。這個過程需要一個適用于整個梁長的慣性矩計算,并使用由線性彈性分析所得的撓度方程。布朗和巴塞洛繆 1996。它建議今后使用進(jìn)行修改過的有效慣性矩方程，如下所示: （6）=未破壞截面處的慣性矩 方程式（6）取自CEBFIP MC90（CEBFIP 1990）加利等（2001）。在負(fù)載情況下，當(dāng)彎矩曲率圖已知,虛擬的工作法可以用來計算結(jié)構(gòu)構(gòu)件的撓度 （11）L
