ANALYSIS OF A MEGA SPACE FRAME ON ELASTIC SUBGRADE WITH MATRIX DISPLACEMENT METHOD

The paper deals with static analysis of a mega space frame. The axial rigidity of columns of subsidiary frames of the mega space frame is simplified as elastic subgrade along the axes of the mega beams. The mega space frame is then composed of the mega columns and the mega beams on elastic subgrade. Static analysis of the mega frame is performed with matrix displacement method considering deformation of the soil. The results indicate that the analytical method is rational and effective.
