| Abstract: | The fundamental principle of drawing influence lines by kinematic method is illustrated by an example of a two-span continuous beam, and the basic method of drawing influence lines is discussed in the paper. The influence lines of bending moment and shear force are calculated by SAP84 software. It shows that the result data are reliable. The method raised in the paper is simple and easy, and it can be popularized to other statically indeterminate structures. |
