Fatigue Properties of Prestressed Beam Column Joints, With Emphasis on Offshore Structures Subject to Wave Loading

摘要

align="left">With the increasing demand for prestressed concrete members in offshore structures, there is a need to evaluate their fatigue strength for wave loading in addition to their static strength. In this study, fatigue loading tests for precast monolithic joints were carried out to determine their fatigue properties both in air and in water. The test specimens consisted of a beam and column. Fatigue design calculations using Miner's rule were conducted for beam column joints subject to wave conditions around Japan.
