摘要:基于课题组提出的新型外包波纹钢板-混凝土组合梁以及对其正弯矩受力性能的研究,以下翼缘钢板厚度为参数,进行了2根新型组合梁的静力加载试验,以研究其负弯矩受力性能。在试验研究的基础上,推导出新型外包波纹钢板-混凝土组合梁负弯矩区抗弯承载力计算公式,并用有限元对公式进行验证,计算值与试验和有限元值吻合良好,可供工程应用参考。

Abstract: Based on the new type steel-encased concrete composite beam with corrugated steel webs proposed by the research group and the study of its positive bending behavior, static loading tests were carried out on two new type composite beams with lower flange plate thickness as a parameter to study the negative bending behavior. On the basis of the experimental research, the calculation formula of the flexural capacity in the negative moment of the new type composite beam was derived, and the formula was verified by the finite element method. The calculated values are in good agreement with the experimental and finite element values, which can be used for reference in engineering application.
Keywords: steel-encased concrete composite beam with corrugated steel webs; negative bending area; bending capacity; plate thickness
