） Abstract： Arched Corrugated Steel Roof (ACSR) is a typical cold-formed thin-wall space steel structure , which has many advantages and widespread applied range
But its bearing capacity is not high and the rigidity is small resulting in the limited application span scope
An inside tension force strengthening method of this structure is suggested in this paper
The strengthening steps as well as corresponding characteristic are introduced in this paper
Finite element models with different span, rise and load case of the strengthening structure are established by using the ABAQUS software
The ultimate bearing capacity and deformation of the ACSR are analyzed and compared for the strengthened and ordinarial structure
The analysis result indicates that the ultimate bearing capacity and rigidity of ACSR with the strengthening method are enhanced remarkably
This strengthening method for ACSR has some certain application value
