The paper presents a practical method of determining earthquake resistance of jack-up floating drilling rigs (FDR) by finding the strength of support columns as their main load-bearing elements. The computation is based on internal forces occurring under acceleration defined by an accelerogram. A FDR general model is considered to determine overall loads along with a separate local model to check the column strength.
