| 摘 要： | 工程结构中受压构件的临界屈曲载荷的计算,是按理想端部约束条件求得的。而实际压杆的端部支承,很难保证支承于理想刚性系统上。因而对支承于弹性系统上的细长压杆,需考虑支坐变位对临界屈曲载荷的影响。本文介绍了利用屈曲系数的计算方法,使计得的临界屈曲载荷更符合实际情况且偏于安全。

THE CRITICAL BUCKLING LOAD FOR THE EARTH AUGER OF DRILL SHAFT FIXED ON THE ELASTICALLY RESTRAINT SYSTEM |
| |
| Abstract: | The calculation of critical buckling load of struts is according to the condition of the end restraint.But the end bearing of actual struts does not guarantee to be supported on the ideal ridigity system.Thus,for the slender struts supported on the elastically system,the influence of the bearing deflection on the critical buckling load must be considered.This article introduces a calculating method ultilizing the buckling coefficient This calculating method makes the critical buckling load more suitable to the actual situation |
