【摘要】 根据已知的M-P-Φ关系,本文分析了腹板有初挠曲的宽腹板工形截面偏压构件平面内的压溃荷载。九个构件的试验结果与理论分析基本符合,验证了理论分析。最后结合工程设计,提出了腹板宽厚比超过规范限值时,工形截面偏压构件平面内承载能力的简化计算方法。更多还原

【Abstract】 Based on the known M-P-Φ relationships derived by the first author of this paper, the in-plane ultimate load capacity of I-section member with slender web and initial buckling subjected to eccentric compression is analyzed. Nine members with large web width- thickness ratios have been tested to failure. The agreement between tho calculated and the test results verifies tho reliability of the analytical method. Furthemore a simplified calculating formula is presented for predicting tho in-plane ultimate load capacity of such members.更多还原
