The method of changing the structural calculation graph is to change the structure of the load to change the structure. The method of calculating the graph is to change the condition of the load distribution, the force transmission path, the nature of the joint and the boundary conditions, and add additional rods and supports and apply. Prestressing, a method of reinforcing the structure in consideration of space coordination work;
If the structure can be reinforced by the following method of increasing the structure or the stiffness of the member, the support is increased to form a space structure and the space structure is used for checking.
Adding support increases the structural stiffness, or adjusts the natural frequency of the structure to improve the structural bearing capacity and improve the structural dynamics.
Additional support or auxiliary members are used to reduce the slenderness ratio of the structure to improve its stability. The most important thing in the frame structure is to strengthen the stiffness of a column to withstand most of the horizontal force to reduce the load on other columns.
A tie rod or a moderately tensioned cable is provided in the structure such as the tower to strengthen the rigidity of the structure.
For the bent bar, the following method of changing the internal force of the section can be used and then reinforced.
In addition, when the reinforcement of the cross-section of the member is increased by using the enlarged section to reinforce the steel member, the selected cross-section should be in the form of a reinforcement of the technical requirements and consideration of the existing defects and damage.

- Fire resistance - Steel is inherently a noncombustible material. However,when heated to temperatures seen in a fire scenario, the strength and stiffness of the material is significantly reduced. The International Building Code requires steel be enveloped in sufficient fire-resistant materials, increasing overall cost of Steel Structure buildings.
- Corrosion - Steel, when in contact with water, can corrode, creating a potentially dangerous structure. Measures must be taken in structural steel construction to prevent any lifetime corrosion. The steel can be painted, providing water resistance. Also, the fire resistance material used to envelope steel is commonly water resistant.
- Mold - Steel provides a less suitable surface environment for mold to grow than wood.
