For determinate and indeterminate structures, which of the following statements are correct?

A、Under the non-load actions, such as temperature, etc., determinate structure will not generate internal forces, but indeterminate structure will generate internal forces.;

B、Under the load, the internal forces of determinate and indeterminate structures are not related to EI of their members.;

C、Force method and displacement method are two basic methods to analyze statically indeterminate structure. They cannot be used to analyze determinate structures.;

D、The displacement of both determinate and indeterminate structures can be calculated using unit load method.;

E、When the temperature changes, the displacement of a statically indeterminate structure is only generated by the redundant restraining forces.
