Study on shear performance of GRC mesh cloth reinforced hollow brick masonry

glass fiber reinforced cement;  shear strength;  Hollow brick masonry

The hollow brick masonry was reinforced by three methods: cement mortar surface layer, one GRC mesh cloth layer and two GRC grid cloth layers, and a total of 36 small specimens were reinforced, and by comparing with the test results of 12 unreinforced control specimens, it was concluded that the use of two-layer GRC mesh cloth to reinforce hollow brick masonry had a good crack barrier effect, and could significantly improve the shear strength of hollow brick masonry. The influencing factors of the shear strength of the reinforced specimens were analyzed, and a calculation method for the shear bearing capacity of hollow brick masonry reinforced with GRC mesh cloth was proposed. In order to facilitate the application in the project, the construction requirements of hollow brick masonry with GRC mesh cloth are proposed.
