| Abstract: | Combining with the actual automobile storehouse,authors proposed an optimized reinforcement method of adding prestressed cable under the bottom chords of portal frame girder to solve the deficient of strength and stiffness of portal frame.Comparison of the structural performance before and after the reinforcement shows that the reinforcement method is safe and reliable.Moreover,the node design and construction technology of the prestressed cable reinforcement are introduced. |
| Keywords: | portal frame prestressed cable structural performance reinforcement |
