Safety assessment on girth welds of large-diameter X80 pipelines in water network area
You-qi chuyun, 2023 As the soil in the water network area is soft and has large water content, it is very easy to settle, which applies an axial load to the pipeline, and the girth weld under the action of tensile load has a higher risk of failure.

Shear critical R/C columns under increasing axial load [PDF]
, 2020 Structural elements in old reinforced concrete (R/C) frame buildings are often prone to shear or flexure-shear failure, which can eventually lead to loss of axial load capacity of vertical elements and initiate vertical progressive collapse of a building.
