摘要

摘要: 建立了一热电厂格构式三管钢筋混凝土烟囱结构的三种结构方案。将风荷载作为随机动力荷载，对三种方案进行了动力特性计算和风振响应分析；着重探讨了Davenport风谱对各结构方案风振响应的差异，并据此对各方案进行了分析和评价。

Abstract: Three structural schemes for a three-pipe reinforced concrete (RC) lattice chimney are developed.Taking wind load as a stochastic loading, the dynamical characteristics analysis and wind-induced vibration response analysis for the three structural schemes are carried out.Comparisons between the responses of the three structural schemes due to wind loading given by the Davenport spectrum are emphasized and their appraisals are performed at the same time.
