摘要
通过对具有轴对称梯形腹板的H形短柱极限承载力的试验 ,并进行相应的有限元计算与分析表明 ,在静力荷载条件下 ,工程构件常用范围内的楔率对具有相同底面尺寸的H形短柱的极限承载力影响不大 ;变截面构件的轴压极限承载力可以由小端截面的屈服承载力和有效截面承载力之间的较小者确定。
The test of the ultimate bearing capacity of the axially\|compressed H\|shaped steel stubs with thin trapezoid web and the relevant FEM analysis are reported.The results show that the loading capacity of the stubs with thin trapezoid webs is not sensitive to the tapering ratio that changes in the normal use of structural engineering.So the ultimate bearing capacity of this kind of stubs can be determined by the minimum of the yield strength of the smaller section and the post\|buckling capacity of the effective section.
