| 摘 要： | 钢筋混凝土框架偏心节点核芯区受力复杂 ,在地震区和一些特殊环境下 ,出现裂缝后修复较困难 ,采用梁端水平加腋可以节约空间利用 ,有效提高节点核芯区的强度和延性 ,延缓裂缝的出现和发展。现以节点偏心距和梁端水平加腋宽度为变化参数 ,从抗裂度角度来研究偏心节点的抗裂性能 ,提出实用的抗裂度计算公式 ,并与试验结果进行对比 ,吻合较好。 |
| 关 键 词： | 梁柱偏心节点 加腋宽度 有效截面宽度 抗裂度计算 |

| Abstract: | In the eccentric joint core area of a reinforced concrete frame,the forces are complicated.In seismic area or under some exceptional conditions,eccentric joints are difficult to repair when cracks occur.Adopting spread-ended beam,it can save space,efficiently improve strength and ductility in the eccentric joint core area,and postpone the appearance and development of crack.In this paper,the major study parameters in eccentric joints are eccentricity and spread-ended beam width.Cracking resistance of eccentric beam-column joints are studied from cracking resistance capacity.The applied equation for computing crack resistance capacity is proposed.Compared with the test results,the calculated results are in good agreement with them. |
| Keywords: | eccentric beam-column joints spread-ended beam width effective section width calculation of crack resistance capacity |
