| Abstract: | According to the direct stiffness method, the paper derived the stiffness matrix of space prestressing cables. Finite element analysis of prestressed space grids with cables was made and the static calculating program was developed. Some characteristics wasput forward by calculating prestressed diagonal square pyramid space grids with internal cables. |
