摘要
利用结构力学力法原理和对称性导出点对称结构在正对称荷载和反对称荷载作用下的反力和内力特征,并通过例题验算比较可知利用该结论计算点对称结构更加简便。
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.
