The Influence Analysis of Spatial Truss Secondary Stress

The previous research on the secondary stress of plane truss told us that the secondary stress which produced by linking rigid is related with load,member length,linear stiffness,the member's relative axial deformation and so on. Based on the previous research on the secondary stress of plane truss,in this paper,I analyzed spatial force's impact on secondary stress of structure,in order to judge the impact of plane secondary stress and it's experience of distribution whether can be extended to spatial load analysis.
