答案：Under the non-load actions, such as temperature, etc., determinate structure will not generate internal forces, but indeterminate structure will generate internal forces.; Under the load, the internal forces of determinate and indeterminate structures are not related to EI of their members.; The displacement of both determinate and indeterminate structures can be calculated using unit load method.
