Strengthening method of membrane structure shed

The reinforcement method of changing the calculation figure of the membrane structure shed structure refers to the method of strengthening the structure by changing the load distribution, force transmission path, node nature and boundary conditions, adding additional members and supports, applying prestress, considering space cooperation, etc;

The general reinforcement method for changing the structural calculation figure of the steel structure skeleton of the membrane structure shed:

The structure can be strengthened by the following methods to increase the stiffness of the structure or component:

A. Increase support to form spatial structure and check calculation according to spatial structure;

B. Adding supports to increase the structural stiffness, or adjusting the natural frequency of the structure to improve the bearing capacity and dynamic characteristics of the structure;

C. Adding supports or auxiliary rods reduces the slenderness ratio of the structure to improve its stability;

D. In bent structure, the rigidity of a column shall be strengthened to bear most of the horizontal force, so as to reduce the load of other columns
