摘　　要：本文推导了在任意荷载激励下梁单元局部效应的修正公式，在不同荷载激励下对结构进行动力响应分析，计算结果表明，考虑局部效应可以使动内力计算结果更为精确。在进行大型复杂结构的动力响应分析时，通过考虑局部效应，可在计算模型大大简化的同时，获得较为精确的计算结果。In this paper, the local effect modification formulation of beam element under arbitrary excitation is presented. By analyzing dynamic response of structure under different excitations, it is found that more accurate results are obtained when local effect is considered. In dynamic analysis of large-scale complicated structures, the computational model is greatly simplified by considering local effect. Moreover, the accuracy of results is also enhanced.
