摘　　要：以一栋锈蚀钢筋混凝土结构为例,对其受弯、受压、受剪承载力进行计算分析。结果表明随着钢筋锈蚀率的增加,构件的承载能力有不同程度的下降,并比较了不同构件随钢筋锈蚀率增大的配筋变化率,为后续类似结构鉴定和加固提供了参考依据。Taken a rusty and corrosive reinforced concrete structure for example,the bending,bearing and shearing capacity of this structure are calculated in this paper,which showed that the carrying capacity of this structure declined in different degrees as the rust and corrosion rate increased,and with the increasing of the rust and corrosion rate,the change of the reinforcement ratio of different structure are compared in this paper,which provided a reference to the subsequent similar identification and reinforcement of structure.

关 键 词：钢筋锈蚀率 受弯构件 受压构件 受剪构件 配筋率
