A cable-membrane tensegrity structure which is asymmetric, and construction method and design method thereof are provided. The cable-membrane tensegrity structure comprises a central opening and is formed by a ring cable () and three layers of radial cables comprising a suspension cable (), a ridge cable () and a valley cable (), wherein the suspension cable () is located above the ridge cable (), the ridge cable () is located above the valley cable (), wherein one end of each of the suspension cable (), the ridge cable () and the valley cable () is connected to the ring cable (), and the other end of each of the suspension cable (), the ridge cable () and the valley cable () is connected to a peripheral supporting structure (), wherein a coating membrane () is tensioned between the ridge cable () and the valley cable () that are adjacent to each other and function as a skeleton to tension the coating membrane (). The method of constructing the cable-membrane tensegrity structure comprises steps of: lifting step by step the suspension cable (), the ridge cable () and the valley cable () to positions adjacent to respective cable anchor nodes by a traction device, based on a shape of formed cable-membrane tensegrity structure; and tensioning and anchoring synchronously the suspension cable (), the ridge cable () and the valley cable () in place by a tensioning device, so as to achieve a final shape of the cable-membrane tensegrity structure. A multi-stage design method, based on the bearing whole-process, of a cable-membrane tensegrity structure of an opening type is also provided.
