摘要
在日常使用中,高强度紧固件─—高强度螺栓表现出人们所忽略的疲劳问题.以往人们对这种疲劳现象很少了解,也没有对此产生走够的重视,因而其危害性特别大.通过对实物进行试验,初步揭示高强度紧固件中的一些疲劳问题,以提醒人们在选择紧固件时,不要盲目挑选那些强度特别高的,应该合理选择,以防止结构件固疲劳性能差而在使用时产生疲劳破坏,造成人员和财产不必要的损失。
In this paper,high strength binder bolt is considered. Under normal conditions, the tensile strength of high strength binder bolt is very high,but the fatigue strength of it is very short,so it will be broken by such ashort fatigue life easily. If it was used in steel bridge,tower used in building, it may be very dangerous to people,to building etc.We must pay enough attention to it so as to avert a catastrophe.
