摘要
框架扁梁梁端处于弯剪扭共同作用,其梁端扭矩值的确定规范尚没有统一的计算公式。本文对有关文献提出的公式进行分析。利用有关文献试验得到的受拉区纵筋应力应变关系、布置方式等,推导出建议的设计取值公式。通过算例,说明梁端受扭矩的特点和配筋构造。
The terminal section of flat-beam is under the combined action of bend, shear and torsion. In the criterion, there is no unified formula to compute the value of torsion in the terminal section of flat-beam. In this paper, the formulas of other papers are analyzed. According to the stress-strain relation and disposal mode of steel in the tensional region of section from the experimental results of other papers, the design formula is concluded. Through the calculation examples, the characteristic and reinforced details of torsional steel in terminal section of beam are presented.
