Abstract

In recent years, extension of life span of buildings is becoming an important issue in our society. To improve the life span of buildings, rhamen structure construction and long-spanned structures are advantageous. And in order to achieve this goal, structural elements of buildings must be light and slender. As an alternative method, general porous slabs are used frequently domestically and internationally. But the study on the porous slabs using T-deck plate and assembly of light weight precast construction is insufficient at present. In this study, flexural and fatigue tests were performed on six specimens to verify structural performance and serviceability. The main parameters of the specimens were light weight and T-deck plate construction possibility as well as slab thickness. The test results indicated that the strength of porous slabs using T-deck plate and assembly of light weight were much better than general RC slabs and porous slabs without T-deck plate. And stiffness was much better than that of other tested slabs.

최근 들어 건축물의 LCC 분석 결과에 따른 건축물에 대한 수명연장기술 즉, 건축물의 장수명화가 화두로 떠오르고 있다. 건축물의 장수명화를 실현하기 위해서는 요구되어지는 공간의 다변화에 따른 대응이 필요하게 된다. 건축물의 장수명화를 위해서는 라멘구조가 필수요소이며 이와 더불어서 장스팬 구조 또한 필수적 요소가 되는 것이다. 또한 건축물의 고층화, 대형화, 모듈화 되어감에 따라 장스팬 구조의 필요성이 점차 확대되고 있으며, 실현을 위해서는 구성하고 있는 부재의 경량화가 기본 조건이 된다. 이에 콘크리트 슬래브의 성능을 그대로 유지한 채 부재의 단면2차모멘트를 극대화 시켜 휨 저항에 유리한 I형 구조로 형성된 중공 슬래브로 개발한 T형 데크 플레이트와 경량성형재 조립체를 사용한 중공슬래브의 휨 및 진동성능을 파악하기 위하여 실험을 수행하고 그 결과 분석을 통하여 일반적인 철근콘크리트 슬래브의 현행기준의 공칭강도에 대한 규정을 사용하여 경량성형재를 사용한 중공슬래브의 휨 강도 설계를 수행할 수 있을 것으로 판단되었다.
