The Correction of Estimation Theory on Cable's Parameters in Prestress-Mega-Brace Steel Frame Structure

Abstract:

In order to verify the accuracy of estimation theory on cables parameters in prestress-mega-brace steel frame structure, several groups of structure models were designed, and the comparison between numerical analysis and estimation theory was completed, further the cause of large error between them was found out, at last correction formula was put and verified by numerical tests. The study shows that cable parameters of this new structure are sensitive to the side columns axial deformation, and the accuracy of correction formulas is greatly improved owing to considering the influence of side columns axial deformation.
