In Japan, there are some floating structures on the sea. The structures take the form of pontoon and are called “floating artificial base”. Buildings are able to be constructed on it, so the floating artificial base is expected as utilization of ocean space. It is thought the structural design should be considered habitability for human living in a floating artificial base. We investigated an existing floating structure. In the concrete, vertical acceleration was measured and questionnaire survey was sent out for user of the structure in the purpose of grasping the motion and the habitability. The habitability was evaluated by Saito’s diagram. As a result of this, it is confirmed the existing floating structure shows elastic behavior and rigid motion simultaneously. It is obtained a lot of respondents felt the motion most sensitively at the dolphin mooring however they did not think uneasy or displeasingly from results of the questions. Visual is important factor in feeling the motion. The habitability became Work Level according to Saito’s diagram for evaluation. Therefore it is though activities on the structure are not difficulty.
