摘要
采用喷射GFRP聚合物方法加固砌体结构,可在不影响结构力学性能的基础上提高构件的抗拉能力、抗压承载力等。利用有限元模拟,对四面墙体进低周往复试验,通过滞回曲线、骨架曲线等指标,对加固墙体的抗震性能展开分析。研究表明:当喷射厚度为7mm的工况下,斜向X喷射方式提高显著,依托现有实际项目,提出一种针对斜向X喷射加固方式的有限元模型,并于实际工程对比,验证了模型的可行性。
Masonry structures strengthened by spraying GFRP can improve the tensile capacity and compressive capacity of components without affecting the mechanical properties of structures.By means of finite element simulation,this paper analyzes the seismic performance of the reinforced wall through low cycle reciprocating test and hysteretic curve,skeleton curve and other indexes.The research shows that:when the injection thickness is 7mm,the oblique X injection mode is significantly improved.Based on the existing actual project,this paper proposes a finite element model for the oblique X injection reinforcement mode,and verifies the feasibility of the model by comparing with the actual project.
