摘要
本文应用能量原理,证明了利用莫尔(O.Mohr)公式求解超静定结构位移时,由于约束条件不同,在单位状态中,单位荷载是作用于结构的静定基上,还是作用于原超静定结构上,所得的位移结果,有时是一致的;但也有不相同的情况。应予区别。
Energy principle has proved in this paper that as Mohr Formula is applied in calcul ating displacements of statically indeterminate structures, in the unit state, the results of displacements are sometimes identical but sometimes are not, depending on different conditions, i.e, either the unit load acts on the released structures or on the oringinal statically indeterminate structures. This should be distinguished.
