| 摘 要： | 验证了混凝土梁在弯曲变形过程中平截面假定的成立以及因损伤原因而产生的中性轴移动。并在此基础上,运用损伤力学方法,得到了混凝土弯曲损伤演化方程、等效惯性矩以及考虑损伤影响的内力计算。 |

| Abstract: | The remotion of neutral axis and flat-section assumption were proved through the bending test of plain concrete.Based on the assumption,damage evolution equation,equivalent inertia moment of bending concrete and method of internal force calculation were deduced using damage mechanics. |
| Keywords: | concrete bend damage |
