| 中文摘要: |
| 对15根自密实钢筋混凝土简支梁进行了动态测试实验,实验结果表明:随着自密实混凝土强度的提高,其阻尼比降低;随着自密实混凝土梁的固有频率的增大,其阻尼比减小;随着自密实混凝土梁配筋率的提高,第一阶固有频率下的阻尼比降低;各自密实钢筋混凝土试验梁的阻尼比基本介于0.5%～1.0%之间. |
| 英文摘要: |
| In this paper,fifteen self-compacting reinforced concrete beams are used for the dynamic testing.The analysis of experimental results indicate that: The damping ratio of beams decreases with increasing the self-compacting concrete strength;the damping ratio of beams decreases with increasing the natural frequency and with the self-compacting concrete beams reinforcement ratio increased,the first-order natural frequency of the damping ratio reduces.The damping ratio falls in 0.5%～1.0% for self-compacting reinforced concrete beams of vibration test. |
