| 摘 要： | 针对工程中大量存在的结构短柱现象,本文研究了玄武岩纤维布(BFRP)加固矩形短柱的抗震性能。试验结果表明:使用BFRP加固混凝土短柱,试件极限承载力提高效果不明显,但极限位移大幅提高,抗震耗能能力增强,破坏模式由剪切破坏转变为弯剪破坏。同时,试验表明纤维加固量的增加对试件的抗震性能影响甚小。

| Abstract: | Considering the large existence of short columns in engineering,the investigations on the seismic behaviors of short columns strengthened with basalt fiber reinforced plastic(BFRP) sheets were carried out in this paper.It is concluded that the ultimate bearing capacity of short columns with BFRP increased slightly,whereas the ultimate displacements of the members were largely improved and the energy dissipation capacity of short columns increased drastically.Meanwhile,the increase in the amount of reinforce... |
