基于通用有限元软件ABAQUS,介绍了预制和现浇混凝土结合面受力行为的模拟方法,进而建立了精细有限元模型,对预制混凝土空心模剪力墙的受剪性能进行了有限元模拟,最后将模拟结果与已有试验结果进行对比、分析。结果表明,有限元模拟结果与试验结果吻合良好,采用的模拟方法合理、可靠;空心模剪力墙受剪破坏形态受预制和现浇混凝土结合面以及空心模孔型的影响很大,有必要研究确定能充分发挥空心模剪力墙受力性能潜力的孔型。
Based on the general finite element software ABAQUS, the simulation method of the prestressed and cast-in-place concrete joint force behavior is introduced. Then the finite element model is established to simulate the shear behavior of the precast concrete hollow shear wall. Finally, The simulation results with the existing test results were compared and analyzed. The results show that the results of the finite element simulation are in good agreement with the experimental results and the simulation method adopted is reasonable and reliable. The shear failure mode of the hollow-core shear wall is greatly influenced by prefabricated and cast-in-place concrete interface and hollow die hole pattern. Research to determine the hollow mold can fully exert the potential performance of the hole type.
