| 摘 要： | 针对预弯组合梁极限承载能力研究不充分的问题,通过对7片预弯组合试验梁的抗弯强度试验和3片预弯组合试验梁的抗剪强度试验研究,提出了预弯组合梁弹塑性极限状态的破坏机理。在此基础上建立了预弯组合梁弹塑性极限状态的抗弯强度和抗剪强度的实用计算方法,对极限抗弯强度的计算方法进行了试验验证,利用该方法所得计算值与试验实测值吻合较好。该计算方法已应用于多座预弯组合梁桥的设计。 |

| Abstract: | Aimed at the research of ultimate capacity of preflex beam being not enough,bending and shear breakage mechanism on preflex beam bridges considering elastic-plastic properties were proposed out,based on the experiment result of the seven test beams for bending strength and three test beams for shear strength.The practicality design methods on bending and shear strength at limit stages were proposed based on the tests.Above methods were validated by the test results,and matched well with the test data.The calculation method has been applied to designing analysis for several preflex beam bridges. |
| Keywords: | bridge engineering preflex beam experimental research ultimate capacity elastic-plastic analysis |
