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.
