| 摘 要： | 通过对9根配有新Ⅲ级钢的高强混凝土梁的等幅疲劳荷载试验,分析研究了受弯构件的疲劳特性,探讨了其在疲劳荷载作用下裂缝宽度和挠度变化的一般规律和特点。经分析推导,得到了高强混凝土梁在疲劳荷载作用N次后的裂缝宽度计算公式及疲劳刚度计算方法,其计算结果与试验结果符合较好。 |
| 关 键 词： | 高强混凝土 高强钢筋 梁 裂缝宽度 疲劳刚度 |

| Abstract: | 9 beams reinforced by high-strength bars are tested under fatigue loading with constant amplitudes.The fatigue behavior of flexural member has been studied,in which,the deformation characteristics and crack width of the beams are investigated.Through analyses and derivations,the calculation formulas for crack width as well as the calculation methods of rigidity and deflection are presented.The results calculated by the proposed formulas are in good agreement with those of the tests. |
| Keywords: | High-strength concrete High-strength bar Beam Crack width Fatigue rigidity |
