摘要:
通过两批试件(7个试件)9次试验,研究玻璃纤维复合材料(GFRP)加固带壁柱砖墙的平面外受荷性能.由试验结果分析可知,采用GFRP对带壁柱砖墙进行加固,可以有效地提高砖墙的平面外抗弯能力和延性.即可以提高砖墙的极限承载力.对于刚度较大的带壁柱墙体,当GFRP加固量达到一定程度,其平面外抗弯承载能力得到较大的提高,而平面外方向的抗剪承载能力提高有限,导致试件的平面外受荷能力由其抗剪承载能力控制.采用不对称加固,会导致墙体的裂缝开展不对称,从而使得墙体刚度不对称,墙体出现附加扭转,减弱GFRP对墙体抗弯承载能力的加固效果.
Abstract:
It′s carried out the experimental research on out-of-plane capacity of GFRP(glass fiber reinforced polymers) strengthened brick walls with pilaster,by two batch specimens(seven brick wall specimens) for 9 times.The experimental results indicate: GFRP strengthening can effectively increase the out-of-plane flexural capacity and ductility of brick walls,namely,improving the ultimate load-carrying capacity.For larger-stiffness brick walls with pilaster,when increasing the quantity of GFRP to a certain degree, the out-of-plane flexural capacity of the brick walls increases obviously,but the increment of out-of-plane shear capacity is limited,thus the out-of-plane capacity of the specimens is controlled by the out-of-plane shear capacity.When adopting the unsymmetrical strengthening,both crack distribution and stiffness of the wall are unsymmetrical,thus an additional torsion occurs,the GFRP strengthening effect of the wall flexural capacity reduces.
