摘要:
为了分析滑移对受负弯矩作用的部分充填式钢箱-混凝土组合梁弹性抗弯承载力的影响,建立在反向两点对称加载工况下的组合梁微段模型,并推导滑移微分方程,在此基础上得出滑移和滑移应变解析解.根据截面应变分布,进一步推导出组合梁考虑滑移效应的弹性抗弯承载力计算公式.对3根反向两点对称加载的组合梁进行试验,对公式的准确性进行验证,试验得出的结果与公式计算值之间拟合良好.结果表明:考虑滑移的不利影响后,组合梁的弹性抗弯承载力下降明显.
Abstract:
In order to analyze the elastic flexural capacity of negative bending moment regions of partially filled steel box composite beam under the influence of the slip. Infinitesimal element of simply supported composite beams under the two-points symmetric reverse loading is established, and the differential equation of slip is derived to study solutions of slip and slip strain, the formula of elastic flexural capacity is deduced further by the means of the strain distribution of composite sections. The two-points symmetric reverse loading experiment on three composite beams are carried out to validate the accuracy of the formula, and the test results are in good agreement with the calculated results, indicating that the elastic flexural capacity of composite beam decreases significantly by the adverse effect of slip.
