چکیده
In determining the seismic performance of reinforced concrete (RC) structures in national and international earthquake regulations, it is desired to use effective section stiffness cracked RC structural elements during design phase. Although not constant, depends on parameters such as strength reinforcement ratio. this study, beam models with different strength, tensile compression ratios were designed investigate nonlinear moment-curvature relationships coefficients. Analytically investigated calculated from TBEC (2018), ACI318 (2014), ASCE/SEI41 (2017), Eurocode2 (2004) Eurocode8 (2004, 2005) regulations relationships. The coefficient obtained analyses compared given for members regulations. results at end examined by comparing them according models. For constant ratio beams, increasing ratio, values increase. beams increase strength. has been proved be maximum moment bearing capacity flexural ductility sections.

effective moment of inertia of frp reinforced concrete beams
concrete beams reinforced with glass fiber reinforced polymer (gfrp) bars exhibit large deflections and crack widths as compared with steel reinforced concrete beams due to the low modulus of elasticity of gfrp bars. different studies show that aci 318 equation for the effective moment of inertia ie does not predict deflection well for frp reinforced concrete beams. the purpose of this paper is...
متن کاملAn Equation for the Effective Moment of Inertia for Frp-reinforced Concrete Beams
The deflection of concrete beams reinforced with GFRP bars is higher than those which are reinforced with steel bars. The purpose of this paper is to propose a new equation for estimating the effective moment of inertia in FRP-reinforced concrete beams. This will be accomplished by using experimental results and the genetic algorithm approach. Genetic algorithm is used for optimizing the error ...

Abstract: The use of Concrete beams reinforced with a combination of fiber reinforced polymer (FRP) and steel bars has increased dramatically in recent years, due to improvement in strength and flexural ductility simultaneously. In this paper, we proposed a new equation for estimating the effective moment of inertia of hybrid FRP-steel reinforced concrete (RC) beams on the basis of the...
