| 摘 要： | 为确定平板空腹结构的最合理结构高度,对平板空腹结构的刚度特性进行了研究。运用解析法得出了任一平板空腹结构均存在一个最合理结构高度使结构刚度最大、变形最小的结论;总结出上下弦截面尺寸、竖腹杆截面尺寸等主要几何参数对最合理结构高度值的影响规律;并推导了最合理结构高度的计算公式。最后运用有限元方法验证了上述结论的正确性和最合理结构高度计算公式的有效性。

| Abstract: | In order to determine the most reasonable height of flat vierendeel structure, the stiffness characteristics of flat vier- endeel structure are analyzed. Firstly, the conclusion is drawn by analytical method that there is a most reasonable height for any flat vierendeel structure. Secondly, the influence of some main parameters is studied. At last, the calculation formula for the most reasonable height is deduced. Different cases are studied by FEM, and the results confirm the above conclusions and the validity of the formula. |
