| 摘 要： | 本文根据四片PPC箱形约束梁的斜截面疲劳抗裂性试验结果,分析了试验梁在疲劳荷载作用下的受力特点,认为PPC箱形约束梁的疲劳抗裂性较相应的简支梁更为不利,并探讨了PPC箱形约束梁斜截面疲劳抗裂性的计算原理和方法。

| Abstract: | Four PPC restrained box beams have been tested under fatigue loading to study the fatigue diagonal tension cracking strength. It is shown that the strength is less than that of the simply supported T beams. According to the test results, a procedure for calculating the fatigue such strength is provided. |
