摘要 对材料满足Leaderman非线性本构关系、且两端简支的梁—柱的动学模型运用Calerkin方法进行截数据简化变为常微分—积分 。 The integro-prtial-differential eguation that gov er ns the dynmical behavior of homogenous material of the beam-columns obeys the L eaderman nonlinear consitutive relation. In the case of two simple supported end s, the Galerkin meheod is applied to simplify the eguation into a integro-diffe rntial eguation. For a class of certain material, the eguation is further simpli fied to a differential eguation.
