| 3. | The corrosion rate of main bars is the only varying factor considered in this experiment
试验中仅将主筋锈蚀率作为变化因素。 |
| 4. | All specimens were composed of one control beam ( without main bars corrosion ) and eight pieces of corroded main bars beams ( with corrosion rate from 4 % to 12 % )
全部试件包括1根对比梁(主筋未锈蚀)和8根加速锈蚀梁(主筋的锈蚀率范围为4 % - 12 % ) 。 |
| 5. | The analysis on all aspects showed that the mechanics property of the corroded reinforcement concrete beams was affected by main bar corrosion rate and the number of fatigue circles
综合分析表明,主筋锈蚀率和疲劳循环次数影响钢筋混凝土梁的静力力学性能。 |
| 6. | The results of the static tensile experiments showed that the static property of the main bars was greatly changed after fatigue load effect which also changed the mechanics property of corroded reinforcement concrete beams
静力拉伸试验结果表明,主筋在疲劳循环载荷作用后,静力力学性能发生了较大的转变;疲劳循环加载较大地改变了锈蚀钢筋混凝土梁的力学性能。 |
| 7. | Vibration test was done on the beams under different state . main bars of all the specimens were taken out for static tensile experiment after fatigue experiments . it showed that the vibration test cannot predict the fatigue failure of the fatigued beams effectively
疲劳试验中,对梁在不同疲劳状态下的振动特征进行了测试;在疲劳试验结束后,取出梁中主筋进行静力拉伸试验。 |
| 8. | Based on the linear fatigue cumulating damnification theory , the calculation of fatigue cumulating damnification intensity was also modified with main bar corrosion rate , which is the most important factor for fatigue lifespan of reinforced concrete beams
另外考虑到锈蚀率是影响疲劳寿命的最重要因素,基于线性累积疲劳损伤理论,建立了锈蚀钢筋混凝土梁的疲劳累积损伤度修正公式。 |
| 9. | It can be seen from the results that the control beam had good plastic property in the static failure experiment after two million fatigue loading circles . all specimens with corroded main bars were failure under the fatigue loads within one million fatigue circles . fatigue lifespan of reinforced concrete beam was sharply shortened after main bars corroded in it and the beam was destroyed bristly without any prediction
试验结果表明,振动测试不能够对锈蚀钢筋混凝土梁的疲劳破坏做出可靠的预测;对比梁在经过200万次疲劳循环加载后的静力试验中仍表现出良好的延性破坏特征;锈蚀梁在100万次疲劳循环内均因主筋疲劳断裂而破坏;主筋锈蚀使得梁的疲劳寿命急剧缩短;梁发生脆性破坏而没有征兆。 |
