Innovative Stay-in-Place Formwork Method for Reinforced Concrete Columns

Recent earthquakes at Pohang in Korea have caused significant damages to existing reinforced concrete (RC) structures. Particularly, piloti columns of RC structures suffered considerable damages. The objective of this research is to review the feasibility of an innovative stay-in-place formwork method using the Textile Reinforced Concrete (TRC) for RC columns in order to improve seismic performance and reliability. The scope of the study includes 1) a development of a concept for TRC stay-in-place form for RC columns, and 2) designing and manufacturing of TRC form modules. It is expected that structural damage of the property, human injuries or loss of life caused by future earthquakes can be reduced by improving the seismic performance using TRC sitein-place participating form, which can also save the social cost for the recovery from the disaster. © 2019 The Authors.
