摘要
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 general finite element software ABAQUS,the simulation method for the behavior of interface between precast and cast-in-place concrete was introduced. Then,the fine finite element model of shear wall with precast concrete hollow mould was built and the shear behaviors of the shear wall was simulated. Finally,the finite element simulation results were analyzed and compared with the existing experimental results. It is indicated that the finite element simulation results agree well with the experimental results and the chosen simulation method is reasonable and reliable. It can be found that the shear failure mode of the shear wall is influenced by the interface and the shape of holes in precast concrete hollow mould significantly,and it is necessary to study and determine the holes' shape which can maximize the shear wall's potential of mechanical behaviors.
