♦Introduction
- What is benefits
Benefits is selected to the worker in a variety of item that designed to corporate. Workers assigned to them in the welfare budget and the rating based on their lifestyle and welfare items, and they can select the level of benefits.
Based on the selection of staff welfare and benefits of the information is determines the level of that. That was reflect
concrete refers to concrete tie that compression is strong but strengthen reinforcing rod to strengthen seal because is weak to seal.
(1) RC method of construction
Fig 7. RC structure.
If define RC method of construction breifly, because rubing cement and sand, gouge the interval and call method of construction to inlay reinforcing rod.
This method of construction that is called alias rein

1.1 CFT의 정의
CFT(Concrete Filled Steel Tube) - 철골튜브에 콘크리트가 충전된 기둥
1.2 개요
일본에서 1959년부터 연구가 진행된 CFT 구조시스템은 변형성능과 내화성능이 우수하여 널리 사용되어 오고 있다. 콘크리트 채움 강관기둥과 철골보로 된 혼합구조에서 콘크리트는 부가적인 강도와
Concrete)부재, 합성보, 충전강관콘크리트기둥(CFC:Concrete Filled Steel Tube Column), 합성벽, 합성슬래브, 합성트러스, 합성말뚝 등은 합성부재라 한다. 그리고 외주부를 튜브구조로 내부코어를 전단벽구조로 하는 경우와 같이 서로 다른 시스템을 조합하여 건물을 구성하는 것을 혼합시스템이라고 한다.
