摘要
运用小变形弹性稳定理论,通过分析下端刚接的带悬伸段柱的计算模型,导出相应的稳定方程,并将求得的计算长度系数的数值解与下端铰接时的计算长度系数进行对比分析。通过对相应临界荷载的对比分析,指出在确定计算长度系数时常犯的错误。同时给出下端刚接的带悬伸段柱的计算长度系数的设计表格和简化公式。
Based on the linear elastic stability theory, analyzing the mechanical calculating model of the base-fixed overhanging column, the stability equation is established and appropriate effective length factors are given and compared with the effective length factors of the base-hinged overhanging column. Analyzing and comparing the relevant critical loads, the incorrect design methods are pointed out. A table of the effective length factors of the base-fixed overhanging column is given, and the simplified formulas are also suggested.
