To address the problem of the reduced efficiency of prestress introduction in the supporting area due to the wrinkle effect of corrugated steel webs restrained by concrete lining， a new lining with chute-stud connection encasement is proposed. In order to explore the influence of new lining on the wrinkle effect and shear performance of corrugated steel webs， I-steel beam specimens with pure corrugated webs and new lining composite corrugated webs are designed. A numerical simulation scheme is established through the sensitivity analysis of the constitutive relationship， welding residual stress， and geometric initial defect amplitude. The numerical simulation results are compared with the experimental results in the literature to verify the rationality of the simulation scheme. Then， the axial stiffness， strain distribution， buckling mode， and shear strength of the newly lined composite corrugated web and the pure corrugated web are compared. The results show that the numerical simulation scheme can accurately simulate the buckling mode， ultimate bearing capacity， and strain distribution of the structure. After the new lining is installed， the axial stiffness of the beam structure with composite corrugated webs is basically unchanged. The distribution of the normal strain and the shear strain of the pure corrugated web and the newly lined composite corrugated web is basically the same， and the normal strain obeys the quasi plane section assumption， and the shear strain uniformly distributes along the height of the web. The buckling modes of the front and rear webs of the new liner are both interactive buckling modes. After the new lining is installed， the ultimate bearing capacity of the structure is increased by about 23%， and the vertical deflection at failure is increased by about 71%. The new lining improves the out-of-plane stiffness of the web and restricts the development speed of out-of-plane displacement in the early stage. In the late stage of loading， the existence of the new lining limits the development degree of out-of-plane displacement.
