| Abstract: | The point symmetric structure is a kind of special structure. This text makes use of the method of force in structural mechanics and symmetry to educe the contrary and internal force characteristics of the point symmetric structure under the exactly symmetrical loading and the anti-symmetrical loading. Compared to the calculation of the sample question, we found that it ismore simple to make use of the conclusion to calculate the symmetric structure. |
