The loading can be either central or eccentric. See the instructions within the documentation for more details on performing this analysis. See the reference section for details on the equations used. Load Example 鱗滝さん 顔The following model applies to columns simply supported at each end (). Firstly, we will put attention to the fact there are no reactions in the hinged ends, so we also have no shear force in any cross-section of the column. The reason for no reactions can be obtained from symmetry (so the reactions should be in the same direction) and from moment equilibrium (so the reactions should be … 鱗滝左近次 柱やめた理由
