【摘要】 利用结构分析软件ANSYS,对不同跨度、不同矢跨比及不同截面的单层球面网壳结构进行了非对称荷载作用下的非线性全过程稳定分析。通过变化不同的参数,考察荷载非对称分布对单层球面网壳稳定性能的影响规律,对工程设计有一定的指导意义。更多还原

【Abstract】 Based on structure analysis software ANSYS, a non-linear complete-process analysis of stability behavior of single-layer latticed domes with different span and different rise-span ratio and different section is carried out. The effect of unsymmetrical loading distribution to the stability behavior of single layer latticed domes with various parameters is also analyzed. Some important conclusions are acquired and can be used as guidance to engineering design.更多还原
