The roel of cables in large span spatial structures: introduction of recent space structures with cables in Japan

摘要

The use of cables as structural members in large-span spatial structures is increasing. One reason for this is that from an architectural design perspectie, these cables are light and provide an expanded impression of space, while smoothly curving cables cretae soft outlines. A second reason is that from a structural deisgn perspective, these cables provide for the well-defined transmission of forces and raional layout of members in a structural system where members can be arranged so as to make the best use of their individual material properties. Cables are used in a variety of ways. In cable structures they are usd as tensile members, and they help control member stress and deformation of frame structures.
