Analysis and Behavior of Steel Pipe Welded Lap Joints in Geohazard Areas

Karamanos S.A., Koritsa E., Keil B., Card R.J. (2015)

Using advanced finite element simulation tools, which account for both geometric and material nonlinearities, the bending capacity of welded lap pipeline joints is investigated. Following the analysis of plain pipes, ...

Analysis and design of buried steel water pipelines in seismic areas

Karamanos S.A., Sarvanis G.C., Keil B.D., Card R.J. (2017)

This paper offers an overview of available methodologies and provisions for the structural analysis and mechanical design of buried welded steel water pipelines subjected to earthquake action. Both transient (wave-shaking) ...

Bending response of lap welded steel pipeline joints
