本文根据双轴对称I形截面偏压杆限制截面塑性深度和不限制截面塑性深度(压溃)的两种极限状态,按等稳条件计算了翼缘板的宽厚比限值,并提出了简化计算公式。
In this paper, according to the two limit states of biaxially symmetrical I-shaped cross-sectionally biased bar constrained plastic depth and unconstrained plastic depth (crushed), the limit value of the width-to-thickness ratio of the flange plate was calculated according to the isostatic condition, and the simplification was proposed. Calculation formula.
