본문내용

1. 서론
건축물을 축조하는데 사용되는 재료인 ‘철근콘크리트’는 가장 널리 사용된다. 철근은 인장이라는 성질, 콘크리트는 압축이라는 성질에 강한 재료이고 철근은 압축이라는 성질, 콘크리트는 인장이라는 성질에 약한 재료이다. 즉, 철근콘크리트는 철근의 인장과 콘크리트의 압축을 상호 보완하여 만든 재료이다. 철근콘크리트 구조는 내력벽, 기둥, 바닥, 보, 지붕틀, 주계단과 같은 주요 구조 부를 철근콘크리트로 구축하는 구조를 말한다.
철근은 탄성, 콘크리트는 소성재료이다. 그러므로 철근은 재료실험을 했을 때 철근 응력-변형도곡선에서 직선 부분만을 보고 설계를 하고 콘크리트는 압축강도를 보고 설계를 한다.
콘크리트의 강도에는 압축강도, 인장강도, 전단강도, 부착강도 등이 있으며, 건축물에 작용하는 힘에는 고정하중, 적제하중, 풍하중, 지진하중, 적설하중 등이 있다.
건축물에 작용하는 힘에 의해 압축력, 인장력, 전단력, 휨모멘트가 작용한다. 이때, 압축력은 압축 변형을 일으키게 작용하는 힘이고 인장력은 인장 변형을 일으키게 작용하는 힘이고 전단력은 전단 변형을 일으키게 작용하는 힘이고 마지막으로 휨모멘트는 휘어지는 변형을 일으키게 작용하는 힘을 말한다.
이와 같이 우리가 지금까지 배운 것을 바탕으로 Chapter 1의 기본개념, Chapter 2의 재료의 성질, Chapter 3의 구조물 설계의 일반사항, Chapter 4의 보의 휨해석 및 설계의 내용을 심화하여 학습한 뒤 철근콘크리트 구조에 대해 이해를 하고 철근콘크리트 보의 설계방법에 대하여 이해할 것이다.

2. 본론
가. Chapter 1. 기본개념
1) 개요
철골콘크리트(RC : Reinforced Concrete)란 시멘트, 물, 굵은 골재, 잔골재, 혼화재료가 일정한 비율로 배합되어 이루어진 콘크리트에 철근이 보강된 것이다.
콘크리트는 압축력에 저항하므로 콘크리트는 부서지는 파괴가 일어나며 파괴되기까지의 파괴시간이 매우 짧은 취성파괴가 일어난다. 철근은 인장력에 저항하므로 철근은 늘어나는 파괴로 끊어지기까지 파괴시간이 콘크리트의 파괴시간보다는 긴 연성파괴가 일어난다.
