摘要: 为探究工程水泥基复合材料(Engineered Cementitious Composite,ECC)与玄武岩纤维增强复合材料(Basalt Fiber Reinforced Polymer,BFRP)筋复合加固既有人防工程剪力墙的抗冲击性能,对加固后的人防墙开展了冲击试验,同时采用有限元软件ABAQUS,基于已有的试验进行数值模拟。通过与试验结果对比,验证了有限元模型的准确性,进一步分析了荷载等级、ECC厚度等对墙体抗冲击性能的影响。研究表明,随着ECC厚度的增加,整体抗弯刚度以及承载力均得到较大提升,有效控制并延后混凝土开裂时间,降低墙体刚度下降速率。ECC-BFRP筋加固方式能有效提升人防墙体抗冲击能力,为人防工程升级改造提供技术支持。

Abstract: In order to investigate the impact resistance of shear wall reinforced with engineered cementitious composite (ECC) and basalt fiber reinforced polymer (BFRP) reinforcement, an impact test was carried out on the reinforced human defense wall. The impact test was carried out on the reinforced human defense wall, and the finite element software ABAQUS was used to carry out numerical simulation based on the existing test at the same time. The accuracy of the numerical model was verified by comparing it with experimental results, and the influence of load levels and ECC thickness on the wall’s impact resistance performance was further analyzed. The results show that both the overall flexural stiffness and bearing capacity are significantly improved with the increase in ECC thickness. The concrete cracking is effectively controlled, and the rate of stiffness decline is reduced too. It can be concluded that the reinforcement method using ECC-BFRP can greatly enhance the impact resistance of the air defense walls, which will provide technical support for the structure upgrade of civil air defense projects.
