提出采用后张预应力筋对砖砌体结构进行抗震加固的新技术。为验证加固效果,采用MSC.MARC通用有限元分析软件建立后张预应力加固无筋砖墙墙片的有限元模型,进行在水平低周反复荷载下的数值仿真计算,并与试验结果进行对比验证。结果表明,后张预应力加固技术可以显著提高无筋墙体的开裂能力和抗剪承载力,改善墙体抗震性能。 A new technique of aseismatic reinforcement of brick masonry structures with post-tensioning tendons is proposed. In order to verify the reinforcement effect, a finite element model of post-tensioned reinforced non-reinforced brick wall was established by using MSC.MARC common finite element analysis software to carry out numerical simulation calculation under horizontal low cycle repeated loading and compared with the test results verification. The results show that the post-tensioning prestressed reinforcement technology can significantly improve the cracking resistance and shear capacity of reinforced concrete wall and improve the seismic performance of the wall.
