【摘要】 在对碳纤维布加固开洞砖墙模型进行往复荷载试验的基础上,对墙体加固后的抗震性能进行探讨分析,建立了碳纤维布加固砖墙的力学计算模型。结合相关国家规范中砌体抗震承载力计算公式,提出碳纤维布抗震加固后墙体抗震受剪承载力的简化计算公式,并与试验结果进行比较,计算结果与试验结果吻合较好,表明该计算模型能较好地反映碳纤维布与开洞砖墙共同工作的受力机理。更多还原

【Abstract】 Based on the experiment of several brick walls with a door strengthened by carbon fiber sheet under cyclic loading,the seismic capability of these strengthened walls were analyzed,by which the mechanics-calculating model of the strengthened wall was established.Combined with the formulas of the seismic shear capacity of the masonry structure in the corresponding national codes,the simplified calculating formula for the seismic shear capacity of brick wall strengthened by CFRP was presented here.Comparing with the experimental values of the ultimate horizontal load,it demonstrated that this simple calculating model for CFRP strengthened masonry wall accords with the actual working state of the masonry wall together with CFRP.更多还原
