EXPERIMENT ON FLEXURAL CAPACITY OF RC BEAMS STRENGTHENED WITH STAINLESS STEEL WIRE MESH AND PERMEABILITY POLYMER MORTAR

Rehabilitation of RC members with stainless steel wire mesh and permeability polymer mortar is a new method ofstructural strengthening with the advantages of resistance to fire, corrosion and ageing. Experiments were conducted toinvestigate the flexural behavior of four strengthened RC T -beams and one comparative RC T -beam under different types ofloadings, the T -beamswere a reduced scale model of a bridge located in Cangzhou City of Hebei Province. It was analyzedthe influence factors of the strengthened T -beams. flexural bearing capacity and its failure modes. Based on the test results,the design formulae of flexural bearing capacity were proposed.
