Numerical Simulation of Flexural Bearing Capacity g of Partially Corroded Reinforced Concrete Beams 库 r ZENGLi, GUOYuan-cheng,SHANYong(SchoolofCivilEngineering, ZhengzhouUniversity, Zhengzhou 450002, China) 例 o [Abstract] The attenuation law of bearing capacity of partially corroded reinforced concrete beams is the basic problem of structural . durability research.This paper simulates both the effect of partially corrosion on bond strength and the attenuation law of flexural bearing 案 o capacity of the beams with the finite-element program.A method is established to calculate the flexural bearing capacity of the partially E e A corroded reinforced concrete beams by introducing the influence coefficient of corroded steel bar, which has proved tobe rational in contrast to C theresult of actual measurement.It can offer technical reference for rational evaluating the bearing capacity of corroded reinforced concrete m structures in actual project. 模 a [Keywords] corroded reinforced concrete;flexural bearing capacity;numerical simulation;corrosion percentage;bond deterioration 凯 c
