箱形钢构件半熔透对接焊缝的强度验算

Strength checking calculation of partial penetrated butt weld in the box component

针对郑州市某人行天桥工程中箱形钢构件焊缝的设计变更进行了分析,采用了4种方法对变更后的半熔透焊缝强度进行了验算,结果证明强度可以满足要求.为类似的半熔透焊缝计算提供了一些思路和算法,对这类问题的分析具有一定参考价值.

The alteration of design for the weld of the box components in a pedestrian overcrossing engineering is analyzed in this paper. Four methods are adopted to check the intensions of the weld. The conclusion reveals that the intensions of the weld meet the requirement. This paper supplies some clues and approaches for similar welding lines' calculations, which has certain reference value.
