摘要:
为了对较小剪跨比的外贴U型碳纤维布抗剪加固梁的剪切性能进行全面的数值模拟和分析,使用ATENA有限元分析软件,结合断裂能理论和损伤理论,建立混凝土本构模型,并利用已发表文献中较著名的较小剪跨比无腹筋钢筋混凝土梁验证该模型的有效性和普适性. 研究表明,该混凝土本构模型在模拟碳纤维布抗剪加固梁开裂后的裂缝发展分布及构件的非线性力学行为方面具备独特的准确性. 在小剪跨比下,所建立的有限元模型预测的荷载挠度曲线、裂缝发展分布和构件破坏模式等主要力学性能均与实验结果较为吻合.
Abstract:
In order to carry out a comprehensive numerical simulation and analysis on the shear performance of the U-shaped fiber reinforced polymer (FRP) shear-reinforced beams with a small shear span-to-effective depth ratio, we use the ATENA finite element analysis software to establish a constitutive model of concrete combined with the latest achievements of the fracture energy theory and damage theory. The validity and universality of the model are verified by the famous reinforced concrete beams with a small shear span-to-effective depth ratio which has no web reinforcements in the published literatures. The simulating results indicate that the concrete constitutive model has its unique accuracy in simulating the crack development and the nonlinear mechanical behavior of the member after the cracking of the carbon fiber shear reinforced concrete beam. And the advanced model can simulate major shear performances of the specimen such as load-displacement curve, crack development and failure mode.
