Abstract: Finite element simulation during arched trough plate takes shape, which analyzes how spring influences taking arch and deformation of arched trough plate, at the same time, taking experimented research through arched trough plate takes shape, and a expected continuity between the calculated conclusion of finite element simulation and the experimented conclusion provided the theoretical proof for technological parameter of making arched metal roof .
