【摘要】 通过14根短圆木柱试件的试验研究,了解CFRP、BFRP、AFRP 3种纤维布加固试件的受力性能,考察全包、半包、间隔包裹等加固方式及纤维布加固层数对圆木柱性能的影响。研究结果表明,粘贴FRP布的加固圆木柱受力性能得到明显改善,承载力、刚度和延性均得到提高。FRP增强木柱为拓展木材的应用范围提供了有益参考,为提高木材的使用效率提供了机遇。更多还原

【Abstract】 By 14 short circular wooden tests of CFRP,BFRP,AFRP,the stress performance of these kinds of fiber cloth reinforcement specimen,and the effects of half package,package parcel interval reinforcement and fiber cloth reinforcement plies on circular wooden performance were investigated.Research results showed that,FRP paste cloth round wooden reinforcement force performance is significantly improved,and the bearing capacity,stiffness and ductility can be improved.FRP enhancement for expanding the application range of timber wood provides useful reference for improving the efficiency in the use of wood,provided opportunity.更多还原
