腹板开洞钢-压型钢板组合梁承载力分析比较

Analysis of the Capacity on Web Openings in Composite Beams with Profiled Sheeting

文章通过大量试验数据的整理分析,提出了腹板开洞钢-压型钢板组合梁洞口截面承载力的计算公式。提出的公式考虑了洞口上方组合板对开洞截面抗剪和抗弯承载力的贡献。统计结果表明,公式与试验结果吻合较好,为规范的修订和工程应用提供了依据。

Through test study and analysis a calculating model is given for predicting the capacity of composite beams with web opening. The proposed formulas consider the effects of shear resistance of composite slab. The calculated results are shown to be in good agreement with the test results. Research results presented in this paper will be valuable for engineering practice and revising code.
