Structural mechanics is an important course. We summarized the curriculum contents using the comparative analysis, including the importance and skill of geometry composition analysis, inner force solution of special structure system (eg. threepinned arcuate structure, two rigid body systems, unit construction and so on), two solution methods (namely the force method and the displacement method) of indeterminate structure, formula summary of structure displacement calculation and so on, which can help students to analogize and well apply their knowledge in solving practical project problems.
