The influence of support condition on 2D frame structure

Abstract

Abstract The offshore structure like jacket, jack-up, gravity and tower can be categorized as a column structure subjected to vertical or horizontal load i.e. the structure is identic with the frame structure. Those structures may be idealized as a frame structure with axial or lateral loads acting on the braces. The present study focuses on the influence of support condition to response of the structure in terms of reactions, displacement and deformations. The support conditions are fixed and hinged at the bottom joint. The load distributions of 10 tonnes are applied at the horizontal brace at the top of the structure. The breadth and depth are 1 m and 1.5 m, respectively. The numerical method is performed to analyze the frame structure. The result obtained by numerical method for three models are compared in therms of support reactions, joint displacement and deformations.
