| 摘 要： | 针对混凝土箱涵的开裂问题,采用三维非线性有限元法,对不同的内水压力、配筋率分析了开裂的可能性.开裂准则采用五参数的Willam-Warnke破坏准则.分析结果表明,选用该破坏准则分析箱涵的开裂问题是合理的.

| Abstract: | It takes 3D nonlinear finite element method to cracking analysis for reinforced concrete box girder.Analyze the possibility of cracking during the different amount of reinforcing bar and different inside hydro pressure.Take WillamWarnke criteria with five parameters as the cracking failure criteria.The result shows that this filure criteria is applicable to crackinganalysis. |
