【摘要】 提出了一种采用ＧＲＣ（玻璃纤维增强水泥）加固砖砌墙体以提高其抗剪强度的新技术．通过７６个采用ＧＲＣ加固的小试件和１７个对照试件的试验结果．分析了采用ＧＲＣ加固墙体受剪破坏的形态、影响加固效果的主要因素，提出了计算ＧＲＣ加固砖砌墙体抗剪强度的公式．通过三片足尺寸采用ＧＲＣ加固墙体和对照墙体的试验，进一步验证了理论分析结果，在可靠度分析的基础上提出了可供工程实践应用的采用ＧＲＣ加固砖墙体受剪承载力的计算方法．更多还原

【Abstract】 In this paper, a new technique used in strenthening brick wall with glassfiber reinforced cement is proposed. Based on the test results under shear force of 76 standardized samples of brickwork strenthened with glassfiber reinforced cement, the behaviour and failure modes of such brickwall are discussed in detail, and the formulas used for calculating the brick wall strenthened with glassfiber reinforced cement are given. These formulas show a good agreement with test results, and are proved by the test results of three brick wall strenthened with glassfiber reinforced cement of large size under vertical and horizontal loads. By the reliability analysis,the design method of such strenthened brick wall for practical use is also proposed.更多还原
