API 650 PARA. 5.10.1에 보면

a. A supported cone roof is a roof formed to appromaxately the surface of a right cone that is supported
    principally either by rafters on girders and column or by rafters on trusses with or without columns.

b. A self-supported cone roof is a roof formed to approximately the surface of a right cone
    that is supported only at its periphery.

이렇게 정의돼 있습니다.

Center Column이나 Girder없이 Internal Rafter만 Roof에 장착될 경우
Supported 인지 Self-supported인지 좀 알려주세요.

적용자료 혹은 엔지니어마다 기준이 틀리네요.

답변주시는 분들 큰 복 받으실겁니다
