What are the advantages and disadvantages of prestressed concrete structure compared with ordinary concrete structure?

Prestressed concrete members have the following main advantages:

① Good crack resistance and high rigidity.

(2) saving materials and reducing structural weight.

(3) Improve the shear resistance of members.

④ Improve the fatigue resistance of components.

⑤ Improve the stability of compression members.

⑥ The application scope of reinforced concrete structure is expanded.

But everything is relative, and prestressed concrete structures also have their own limitations:

(1) The manufacturing process is complex and the construction quality is high.

(2) It is necessary to have certain special equipment, such as tensioning equipment and grouting equipment.

(3) The project cost of prestressed concrete structure is high, and the project cost with few components is high.
