| 摘 要： | 以具有实际工程意义的40m跨度,矢跨比为1/3,同时考虑圈梁和下部柱及柱间支撑的K8型单层球面网壳为研究对象,利用ANSYS有限元程序,在考虑几何非线性和材料非线性效应的条件下,研究该结构在三向强烈地震荷载作用下的动力响应、失稳模态及破坏机理,并分析下部支承结构、杆件弯曲变形对网壳结构动力稳定性的影响。 |
| 关 键 词： | 球面网壳 地震作用 破坏机理 动力稳定 |

| Abstract: | The dynamic responses, instable mode and failure mechanism of 40 m-span and rise-span ratio of 1/3 K8 single-layer spherical reticulated shell with supporting structure under three-way strong earthquake action are investigated by the finite element program ANSYS in the paper. In the studying, both the geometric and the material non-linearities are taken into consideration. At the same time,it is analyzed the effect of the supporting structure and bending deformation of the members on the dynamic stability o... |
