| Abstract: | The method of converting prestress actions to equivalent nodal loads is widely used in the design of prestressed concrete bridges. According to the principle of action force and reaction force, the calculation formula and method of prestressing equivalent load are deduced. The method has the merits of high calculation efficiency, which is applicable to computerize by finite element method and can be used in calculation of spatial prestress, the example of calculation attached. |
