本文叙述了为研究梁的破坏方式和腹板横向加劲的特性而在大比例尺板梁模型上进行的五个试验。试验结果表明,拉力场机构法能较准确地预估这种腹板密布加劲肋的梁的极限承载能力。试验结果还表明,现在提出的腹板横向加劲肋的设计方法是安全的,但也是保守的。
This paper describes five experiments carried out on a large-scale plate-beam model to investigate the failure modes of beams and the characteristics of transverse web stiffeners. The experimental results show that the pull-field mechanism method can predict the ultimate bearing capacity of the beam with a kind of web stiffener more accurately. The test results also show that the proposed web transverse stiffener design method is safe but conservative.
