Combined with the design plan of the prestressed tightwire arch roof in a gymnasium, this paper studied the optimize choose form and the finite element analysis methods for the prestressed tightwire arch, compared the effects of force and displacement of the prestressed tightwire arch made by different schemes of cable and skewback anti-thrust rigidity. In the end, some suggestions for design are presented.
