| 摘 要： | 通过对7根钢筋混凝土梁的静载试验,分析剪跨比和钢筋锈蚀率对试验梁的承载力、荷载-挠度曲线、钢筋和混凝土应变变化等力学性能的影响.结果表明,剪跨比仍是决定钢筋锈蚀梁性能的主要因素,钢筋锈蚀程度并不改变其破坏类型,但钢筋锈蚀严重时会出现由适筋破坏向少筋破坏转变的现象.随着钢筋锈蚀程度的增加,钢筋混凝土梁的承载力和整体刚度均...

| Abstract: | Based on the static load test of 7 RC beams,the influence of the shear span ratio steel corrosion rate on the beam load carrying capacity,load-deflection curve,reinforced bars and concrete strain,is analyzed.The test results indicate: the shear span ratio is still the main factor influencing the properties of beams with corroded reinforcement;the steel corrosion rate doesn't change the failure modes,but the serious corrosion can turn the beam from the balanced reinforcement to the under reinforcement.With i... |
