Finite Element Analysis of the Greenhouse Canopy Effect with Seismic Load

The finite element model about greenhouse canopy of seismic analysis was setted up, The finite element analysis software ANSYS was used to study structure displacement, stress analysis on greenhouse shed. The results showed that the dangerous part of the canopy were located on upper chord members,lower chord members, web members of the framework and the lower and upper, the inside of both sides of the wall with seismic load. Corresponding to this results,the main destroied form were the framework damage caused by the bending deformation of upper chord members, lower chord members and the upper web members and the unstability caused by the distortion of both sides of the wall.
