PVC管约束钢筋玄武岩纤维混凝土(BFRC)短柱轴心受压试验研究
Experimental Study on PVC Pipe Restrained of Reinforced Basalt Fiber Concrete (BFRC) Short Columns under Axial Compression
摘要
Abstract
To study the mechanical behavior of PVC-BFRC stub columns with PVC-BFRC bars,the effects of the short columns of reinforced concrete(RC),the short columns of reinforced concrete basalt fiber reinforced concrete(BFRC),the short columns of PVC-BFRC were studied and analyzed.The results show that the ultimate load-carrying capacity of PVC-BFRC short column is 45.7％higher than RC short column,11.6％higher than BFRC short column,and the ductility of PVC-BFRC short column is better than RC short Column,PVC-BFRC short column axial compression ultimate load capacity and PVC pipe damage almost simultaneously.The vertical displacement of PVC-BFRC short column at the peak value is obviously greater than that of the other two short columns,and the plasticity is more obvious.The results show that under the combined action of PVC pipe and chopped basalt fiber,the axial load of reinforced concrete short columns and the ductility of reinforced concrete short columns is improved.关键词
