| 摘 要： | 高速公路收费站采用的顶锥式膜结构在遭遇大风之后，容易出现破坏。对此种类型的膜结构，进行了详细的结构风压分布数值模拟，得到此类结构在锥顶处的风压远远大于常规设计取用的数值，进而阐述了此类膜结构在风荷载作用下的破坏原因。并在后续的设计中对锥顶的形状进行适当的修改来减小其风压系数，采取适当的构造措施来减少破坏的发生。

| Abstract: | Taper membrane structures for coastal highway toll stations were easy to be destroyed after suffering several typhoons. Numerical simulation of wind pressure distribution on this kind of membrane structure has been performed, and it has been found that the wind pressure on top of cone is much bigger than that in usual design, the destructive reason of the kind of membrane structure under wind load was expounded. The shape of the cone top was modified to reduce the wind pressure coefficient in following desi... |
