| 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. |
