基于ABAQUS的镶嵌式混凝土加固、修复技术研究
|
摘要
本工作通过镶嵌方式对开裂混凝土构件进行修复、补强、加固,确保混凝土构件具有不低于开裂前的初始力学性能。对镶嵌件修补的混凝土构件进行抗折试验,并基于材料力学理论对镶嵌件组合进行承载力计算,再通过ABAQUS构建算例的有限元模型观察变形过程中应力的分布情况,研究修补后混凝土的弹塑性工作性能,并进一步优化镶嵌件的工作性能。分析试验、理论数值计算和有限元分析结果表明,本工作研究的镶嵌式加固方式,对含裂缝的水泥制品的抗折性能有明显提高,有限元软件可以有效模拟试验结果,在接下来的研究中可以部分代替试验工作,对镶嵌方式加固混凝土结构技术进行更深入的研究。
In this work, the cracked concrete members are repaired, strengthened and reinforced by the inlaying method to ensure that the concrete members have not less than the initial mechanical properties before the cracking. In this work, the flexural test of the inlaid concrete members is carried out, and the bearing capacity calculation is carried out based on the material mechanics theory. Then the finite element model of the ABAQUS construction example is used to observe the stress distribution during the deformation process, and the repaired concrete is studied. Elastoplastic performance and further optimize the performance of the insert. The results of analytical tests, theoretical numerical calculations and finite element analysis show that the inlaid reinforcement method studied in this work has significantly improved the flexural performance of cracked cement products. The finite element software can be used to replace the experimental work in the next study,and inlaid reinforced concrete structure technology should be further studied.
