STRENGTHENING METHODS FOR CYLINDRICAL MASONRY VAULTS
Abstract
The technical condition and failure mechanisms of exploited cylindrical masonry vaults are discussed. Known techniques for their strengthening are given. The advantages and disadvantages of strengthening techniques by installation of solid reinforced plaster layer and stiff edges(beams) are described. The strengthening of vault by composite mesh (FRP) reinforcement is offered as more modern and preferred method. Installation technology and advantages of strengthening system by using composite materials which is called Fibre Reinforced Cementitious Matrix (FRCM) are presented, within which, instead of an epoxy adhesive, used special plasters. The results of experimental investigations of reinforced and unreinforced masonry compression bending specimens are analyzed. It is concluded that the greatest effect of composite mesh (FRP) reinforcement can be obtained for semicircular vaults, and the least effect for shallow (low angle) vaults.
