New method of evaluating the compressive strength of concrete in structures using BOSS: Broken off Specimens by Splitting Method was developed. Applicability of BOSS specimen was examined by comparing the compressive strength of specimens taken from a model structure by coring and by BOSS. Effects of water-cement ratio and the sampling height on compressive strength were studied with the variance analysis. It was confirmed that high correlation was found between compressive strengths of BOSS and core. Thus the BOSS based simple formula may be applicable to the prediction of compressive strength of concrete in structures.
