Initial analysis in made of the mode of longitudinal stress in the pipeline under vertical load.
对垂直荷载作用下的管道纵向受力模式进行了初步探讨。
Evolvement process of longitudinal stress and residual stress field after welding are obtained.
得到了焊接过程中纵向应力的演变规律与焊后应力场的分布情况。
The maximum horizontal force that the pier must resist and the longitudinal stress of the stringer are studied.
并计算施工过程中墩顶必须承受的最大水平拉力以及钢纵梁的最大轴向压应力。
Through the analysis on computation results of different tensioning schemes, the suggestions of reducing longitudinal stress for application safety are put forward.
