| 1 | Experimental Study on Concrete Columns Confined by BFRP-PVC Tubes Under Uniaxial Loading显示文摘This paper presents an experimental study on the behavior of circular concrete columns reinforced by BFRP-PVC tubes under uniaxial loading.A total of six specimens were prepared and tested under uniaxial loading.The main parameters varied in the tests were strengthening ratio and strengthening approach of BFRP.The performance,such as failure modes,ultimate bearing capacity and stress-strain curves,was investigated in details and a formula was proposed to predict the compressive ultimate strength.The results show that this kind of confined columns obviously improves the ultimate bearing capacity,and the ultimate bearing capacity increases with the strengthening layers.The formula proposed is applicable and efficient for prediction of the ultimate bearing capacity as well. | 姜绍飞 DAI Tianjie FU Dabao WU Zhaoqi LINing | 2012 | 沈阳建筑大学学报(自然科学版)2012，28，1： | 1 |
