摘要
本文讨论了受非对称集中冲击作用下的两端固定刚塑性梁的动力响应分析。文中给出了当特征长度 l=6M_0/Q_0小于冲击力作用点到梁端距离时,计入剪切滑移时的解只需对塑性弯曲动力响应问题的解略加修正便可得到,并给出了具体论证和数据结果。
The shear and bending effects of rigid-plastic dynamic response for a mss striking on a fully clamped beam at arbitrary location in the span are discussed.The solution taking account of shear and bending effects can be obtained from the solution of pure bending response givenby the wellknown literatures with slight correction given in this paper.
