원심성형 중공PC기둥의 압축 실험
An Experimental Study on the Axial Strength of Centrifugall Formed Shell PC Columns
초록
최근 급속한 속도로 변화하는 현대 사회에서의 건설 현장에서는 공기 단축 및 자재의 절감을 통한 공사비 절감이 절실히 요구되고 있는 실정이다. 현재 현장에서의 거푸집 공사기간이 전체 공사기간의 1/4정도 차지하고 있으며, 공사비는 전체 공사비의
Recently, Construction Business, is changing very quickly, exceedingly needs to slim down the construction expensive by reducing material costs and the term of works. The term of formwork takes 25% of the term of works and costs 15% to 20% of the cost of construction. Hereupon, the purpose of this study is to investigate the Axial Strength of Centrifugall Formed Shell PC Columns that can reduce the term of formwork, the costs of material, the difficulty of throwing away the waste. Shell PC Column is loaded stirrups and manufactured at factory, so it has good points like construction's quality control and part's precision. However, it needs to be tested for checking bonded ability because it is set up at core and coverd with concrete. therefore this study is necessary three type of columns, which are a RC column, different type of two compressive strength core concrete columns and a Shell PC Column. By three columns, this study compare with and analysis three columns's bonded and Compressive Behavior abilities.
