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.
