喷射玻璃纤维聚合物(SGFRP)加固8个砌体柱试件,分别进行轴心受压试验和偏心受压试验研究,描述了试验砌体柱的破坏形态,分析了喷射玻璃纤维聚合物抗压加固砌体柱的加固效果.试验结果表明:加固对砌体柱的极限承载能力有较大的提高.不同的喷射GFRP厚度、短切纤维长度以及是否贴玻璃纤维布对砌体柱的承载力也有一定的影响,通过对比不同加固方式与承载力的关系,提出合理的加固建议.文中还根据砌体柱的材料力学特征建立计算模型,并结合试验研究提出相应的受压承载力计算公式,为定量分析喷射GFRP加固砌体柱进行了探讨.
Sprayed glass fiber reinforced polymer (SGFRP) reinforced eight masonry column specimens, respectively, axial compression test and eccentric compression test study describes the experimental masonry column failure morphology, analysis of jet glass fiber polymer compression The results show that the ultimate bearing capacity of masonry pillars is greatly enhanced with different thickness of GFRP, length of chopped fiber, and the bearing capacity of masonry pillars But also has a certain influence.According to the relationship between different reinforcement methods and bearing capacity, a reasonable reinforcement proposal is put forward.According to the material mechanics characteristics of the masonry column, a calculation model is established and the corresponding compressive bearing capacity formula is put forward based on the experimental research, The quantitative analysis of GFRP reinforced masonry column was discussed.
