| 摘 要： | 对水塔进行动力分析时 ,可简化为单自由度体系。其基本周期可据在水塔水箱重心处单位水平力作用下该处的水平位移δ ,按“顶点位移法”来计算。然而δ的计算至今缺少便于设计者应用的手算简化方法 ,为此本文提出了一种确定支架式水塔δ的简化计算模型及相应公式。公式形式简单 ,物理意义明确 ,便于计算。通过具体算例 ,采用本文方法与用Su perSAP程序作三维有限元计算对比 ,两者结果十分接近

| Abstract: | A simplified calculation method and corresponding formulas used to determine the horizontal displacement of framed water tower are established.The scheme of formulas is simple with the clear meaning and convenience in calculating and designing for framed water tower.The calculated results of practical examples are obtained based on both the method suggested in this paper and the 3-D FEM analysis using SuperSAP program.The two sets of results are found to be in agreement very much. |
