| 摘 要： | 带飞杆的伞形膜结构是设计中经常采用的一种结构形式,其设计的难点在于必须将结构中的飞杆、拉索等弹性构件与膜结构一起进行联合找形,否则无法准确得到找形形状以及构件的内力。通过自编的程序对这一特定的结构形式进行了分析并得出一些规律性的结论。

| Abstract: | The umbrella membrane structure with flying bars is a main structural form in design.The difficulties in design are that the elastic bars′ displacements must be taken into account during the form-finding,or the initial equilibrium shapes of the membrane or the bars′ forces can not be calculated accurately.This special structural form is analyzed and some regularity conclusions are given. |
