STATISTICAL ANALYSIS ON INSPECTION RESULTS OF UN-REINFORCED CONCRETE COASTAL FACILITIES

Abstract

 This paper discusses the cracking of un-reinforced concrete coastal facilities. Inspection on unreinforced concrete coastal facilities has been conducted to measure crack widths, length and numbers. The inspection data are analyzed based on the statistics analysis and the crack properties are quantitatively evaluated. As the results, it is proposed that a method to predict the extremal value of crack width in the facilities can be estimated with high accuracy only by investigating about 20% of all the spans.
