摘要
分别采用水泥砂浆面层、一层GRC网格布面层、二层GRC网格布面层三种方法加固空心砖砌体 ,加固的小试件共计 36个 ,通过与 12个未加固对照试件试验结果相比较 ,得出采用二层GRC网格布加固空心砖砌体有较好的阻裂效果 ,且能明显提高空心砖砌体的抗剪强度 ;分析了加固试件抗剪强度的影响因素 ,提出了用GRC网格布加固空心砖砌体的受剪承载力计算方法 .为方便工程中的应用 。
In this paper,brickwork is reinforced by three methods:grout layer,one layer of GRC gridding cloth and two layers of GRC gridding cloth,reinforced samples sum to 36.Comparing with 12 un reinforced samples.It shows that reinforced samples with two layers of GRC gridding cloth can prevent the cracking and improve the shear capacity.By analysing the factors of shear capacity,the formulas used for calculating the shear capacity of brickwork reinforced with GRC gridding cloth are given. Some construction desires for brickwork strengthened with GRC in practice are put forward.
