| 摘 要： | 根据有限元计算和正交回归分析资料，提出了水电站厂房中带形牛腿轮压分布宽度的概念和计算公式，并通过两个带形牛腿结构试验，验证了轮压分布计算宽度定义的正确性．提出的公式计算简便，其计算值与试验结果符合程度较好．在此基础上，提出了带形牛腿的计算方法和配筋构造要求．经比较，采用本文建议的带形牛腿计算方法比现行的计算方法更为合理．

| Abstract: | In this paper a definition of distribution width of loads acting on a long narrow bracket in hydropower plant is presented based on the results with FEM,and the definition is validated by two tests of long narrow brackets.Statistical formulas of the distribution width are obtained from the com- putation result.The formulas are simple and convenient to use.The distribution widths obtained by using the formulas are is agreement with experimental data.On the basis,a design method of long nar- row bracks is presented and the details are proposed.The present design method is more reasonable than the carrent one and considerable economic benefits can be achieved from the using of it. |
