摘　　要：探讨了随机脉动风压作用下,结构的局部动力效应问题,通过实例计算证明了局部动力效应影响不可忽略,这为正确分析脉动风压下结构的动力响应,准确、可靠地指导工程设计提供了理论依据。The local dynamic effect under stochastic fluctuation wind pressure was systematically analyzed. The related formulas are derived. By using the method, the unitary dynamic internal force and bending moment for a column structure under stochastic fluctuation wind pressure are calculated. It has been found from comparison that the results have become more accurate when local effect is considered under stochastic fluctuation wind pressure. Moreover, some useful results are obtained. These are beneficial to engineering design.
