| Abstract: | 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. |
| Keywords: | prestressed concrete frame flat-beam torsion in flat-beam joint details |
