中文摘要:
      为了解地震作用下纤维编织网增强钢筋混凝土柱的抗震性能,采用钢筋、混凝土、纤维编织网浇筑纤维编织网增强钢筋混凝土柱,编织网主材为碳、玻璃纤维束;利用电液伺服加载系统为试件加载地震作用,监测相关数据,部分试件置入氯化钠溶液进行多次干湿循环。不同环境下的实验结果显示:纤维编织网层数越多,纤维编织网增强钢筋混凝土柱承载能力越强,抗震性能越好;配箍间距较大时,纤维编织网增强钢筋混凝土柱的抗震性能仅在地震作用的后期呈现较差状态;干湿循环次数越多,纤维编织网增强钢筋混凝土柱承载力越弱,抗震性能越差。对于氯盐环境而言,可增加纤维编织网增强钢筋混凝土柱的抗腐蚀措施改善抗震性能。适当增加纤维编织网的数量、降低配箍间距有利于提升纤维编织网增强钢筋混凝土柱的抗震性能。
英文摘要:
      Reinforced concrete and textile are used to cast reinforced concrete columns using carbon and glass fiber bundles as the main materials to understand the seismic performance of the textile reinforced concrete columns under earthquake. An electro-hydraulic servo loading system is used to load the seismic monitoring data for the specimens. Some specimens are placed in the sodium chloride solution for multiple dry-wet cycles. The experimental results obtained under different environments denote that the bearing capacity of the reinforced concrete columns is strengthened and the seismic performance of the reinforced concrete columns is improved with increasing number of textile layers. The seismic performance of the textile reinforced concrete columns is only poor in the late stage of seismic action when the hoop spacing is large. The larger the number of dry and wet cycles, the weaker will be the bearing capacity of the textile reinforced concrete columns and the seismic performance of the reinforced concrete columns. In a chloride environment, the corrosion resistance of the textile reinforced concrete columns can be increased to improve the seismic performance. Appropriately increasing the number of textile layers and reducing the hoop spacing can improve the seismic performance of the textile reinforced concrete columns.
