摘　　要：从自然暴露１０年的钢筋混凝土梁中，按钢筋锈蚀损伤程度选取６根梁进行承载力试验，结果表明，钢筋锈蚀程度对梁的承载力有明显影响，钢筋锈蚀越严重，承载力越小，但在考虑钢筋锈蚀损伤后，锈蚀钢筋混凝土梁的承载力计算仍可采用规范方法。According to rusty degree of steel-bar, the six RC beams are selected in those beams that have been exposed to the air for 10 years. the experiment for bearing capacity of the six RC beams, reveals that rusty degree of steel-bar had evident influence on bearing capacity of RC beam. The rustier steel-bar is, the lower bearing capacity of beam is. Considering influence of steel-rusty, bearing capacity of beam with rusting steel-bar still can be calculated with the standard method.
