Abstract:
The distributions of stress and deformation were computed for the portal frame with prestressed cable-strut under various load conditions based on a grain warehouse with 72 m span, and the results were compared with that of different long-span portal frames. The method was developed to analyze the mechanical principle of portal frame with prestressed cable-strut. The results show that the effect of prestress of the portal frame with prestressed cable-strut is more effective than common prestressed frames, and effectively improves the mechanical behavior of portal frames due to deformations of the strut and cable should be considered in the design of portal frame; therefore, the deformations should be computed by geometry nonlinearity.
