| 摘 要： | 为避免结构过早出现因局部破坏而造成整体失效的情况发生,对网架结构在竖向荷载下的受力状况进行了分析,并采取加强重要杆件截面的措施,使结构的极限承载力得到了显著提高.所提高的承载力对抵御超越荷载有一定的积极作用,增强了网架结构抗灾害能力.

| Abstract: | The grid structureis often overall failure for local damage under the disaster load.In order to avoid the situation,the load cases of the grid structure under vertical load are analyzed in the paper.Taking the measure of strengthening the important bars,the ultimate bearing capacity of the structure is improved significantly.The improved load bearing capacity plays a positive role in resisting exceeding loads,and the anti-disaster ability of the structure is improved. |

| Keywords: | grid structure vertical load incremental step anti-disaster ability |
