Ultimate Bending Strength Behaviors of Tubular Connections on Floating Type Wave Energy Converter

Abstract

In terms of structural strength, the weakest spot of the floating pendulum wave energy converter is tubular connections which are located between a floater and a damping plate. It is expected that maximum stress is occurred when bending moments applied in operational condition. In the present study, a bending strength behavior of tubular connection is investigated. An important aspect in the design of tubular connections is the buckling and ultimate strength behavior. When the buckling is occurred, in-plane stiffness of structure is remarkably decreased. To prevent such forms of buckling, longitudinal and vertical bracings are installed. The six types of bracings are covered to maximize the ultimate strength of tubular connections. The numerical study of ultimate bending strength behaviors for tubular connections is employed using a quasi-static approach. This study takes an advantage to perform a structural detail design.ents applied in operational condition. In the present study, a bending strength behavior of tubular connection is investigated.
