Abstract

Research purposes: The applicability of using ANSYS in designing steel netlike roof is studied and the feasibility of designing the steel netlike structural parameter is analyzed.

Research methods: The steel netlike roof's finite element model is constructed by use of the software ANSYS. The model is loaded and calculated on the base of considering structural actual load，material property ， geometry characteristic， boundary condition etc.

Research results: The values of steel netlike roof's vertical displacement and the poles’ axial force are gained by calculating the structural displacement and internal force. The roof's transmutation and intensity satisfy the demands of the correlative criterions.

Research Conclusions: The Finite Element Method is provided applicability in calculating steel roof's netlike designed parameter. Finite Element Method can be used directly in constructing finite element model ， inputting correspond parameter ， plotting out model 's mesh，loading the model and solving the model. Finally the needed mechanical parameter is got. Similarly Finite Element Method can be used as an aided tool to design other engineering structural parameter and to calculate structural mechanical characteristics.
