摘要: This paper presents numerical results of structural post- fire bahaviour I-shaped beam-to-chord joints in offshore platforms topside. Considering the high risk events oil/gas platforms, this study focuses on behaviour these connections at condition. A highly detailed three-dimensional (3-D) finite element (FE) model connection has been created using ABAQUS software. Steel members and components are considered to behave nonlinearly. The experimental tests conducted I shape beam-to-tubular column furnace conditions compared, obtained failure modes moment-rotation-temperature characteristics good agreement with those associated tests. validated used conduct parametric studies generate theoretical data help develop understanding joint post-fire
