【摘要】 以台州大学风雨操场屋盖为例 ,简要介绍了在跨度大、支承结构较柔的实际情况下 ,采用面内稳定索辅助脊索、谷索共同承力的张拉膜结构的设计过程。并结合风洞试验结果 ,对三种找形方案 ,即不采用稳定索、采用交叉稳定索、采用斜稳定索的结构形式在不同工况下的受力性能进行了比较分析。更多还原

【Abstract】 The design of tensioned membrane structure of gymnasium in Taizhou university is introduced. Considering its long span and flexible supports, a specific configuration, which employs stability cables to resist external loads with the help of ridge and valley cables,is presented. Three types of form-finding are offered. Meanwhile, combined with the data of wind-tunnel test, the working behaviors under different wind loads are compared and analyzed.更多还原
