Abstract: A submarine pipeline is idealized as a linearly elastic continuous beam subjected to vertical loads, and supported on a discretized frictionless seafloor profile. The structural analysis of this beam is considered as a ...

Abstract: This paper proposes a new planar reinforced concrete (RC) formulation capable of modeling geometric and material nonlinearity. A new co-rotational sub-parametric formulation consisting of a four-noded element with quadratic ...

Abstract: An accurate and unified finite element description is presented, in both stiffness and flexibility formats, of the response of planar elastic beams subject to terminal loads. The stability and bowing functions are ...
