Mortar Replacement Reinforcement Method for Existing Masonry Structures

摘要

For load-bearing capacity reducing of the walls of multi-storey masonry structure caused by the lower mortar strength and quality defects, the mortar replacement method was used to reinforce the perforated brick load-bearing walls. The strength of mortar used for replacing, the depth of replacement, construction methods and quality control have been studied. The reliability of this method is verified by testing in situ including axial compression test and double brick double-shear test for reinforced brick masonry. This method could be also used in reinforcement for the historical masonry buildings.
