Combining with the National Natural Science Foundation ofChina(No.50478032), following researches were done in this thesis: 1 The variation regularity of the ultimate anti-bending capacity of therectangular-sectioned beam with different corrosion has been obtained through thequalitative analysis of 48 beams (32 corroded beams and 12 comparing beams) withaccelerated corrosion; 2 The conclusion has been obtained that the strain of corroded steel bar andconcrete no longer fit in with the assumption of plane section through the analysis ofthe strain data, the strain relation of steel bar and concrete in the mid-span section ofvariously corroded beams at ultimate has been obtained. Through the building of newgeometric relation, the expression of the height of compressive area in the corrodedbeam with rectangular section has been deduced, and the formula with corrosion rateas the main variable for the anti-bending capacity of the corroded concrete beam hasbeen suggested and verified by experiment.; 3 The influence of steel bar corrosion and the concrete regression to the flexureductility coefficient of the corroded structure component has been analyzed. Based onthe relation of steel bar and concrete at yield and ultimate, the expression for theflexure at yield and ultimate of corroded reinforced concrete beam, and the model forthe calculation of the flexure ductility has been built.
本文结合国家自然科学基金项目(50478032)"既有钢筋混凝土桥梁时变可靠度研究",主要进行了以下研究工作: 1通过对48根快速锈蚀钢筋混凝土矩形截面梁(32根锈蚀梁和12根对比试验梁)数据的定性分析,得到了不同锈蚀率下,锈蚀钢筋混凝土矩形截面梁极限抗弯承载力的变化规律; 2通过对应变数据的分析,论证了锈蚀构件钢筋和混凝土的应变不再符合平截面假定的结论,并通过回归分析得出了不同锈蚀率的螺纹钢筋梁和光圆钢筋梁在极限弯矩作用下,跨中截面处钢筋应变和钢筋处混凝土应变的关系,通过构造新的几何关系,得出了锈蚀钢筋混凝土矩形截面梁计算受压区高度的表达式,既而得出了以锈蚀率为主要变量的锈蚀钢筋混凝土矩形截面梁的正截面抗弯计算建议公式,并通过试验数据加以验证; 3分析了钢筋锈蚀和混凝土劣化对锈蚀构件曲率延性系数的影响,结合钢筋屈服和极限弯矩两种状态下钢筋和混凝土的应变关系,分别得到了锈蚀钢筋混凝土矩形截面梁屈服曲率和极限曲率的计算表达式;既而推导出曲率延性系数的计算模型。
