Abstract
Concrete columns confined with high-strength fiber composites can enhance its strength as well as maximum strain. In recent years, several equations have been developed to predict the behavior of the concrete columns confined with fiber composites. While the developed equations can predict the compressive strength of the confined columns with reasonable agreement, these equations are not successful in predicting the observed maximum strain of the columns. In this paper, a total of 61 test results is analysed to propose an equation to predict both compressive strength and maximum strain of concrete cylinders. The proposed equation takes into account the effects of confining pressure and cylinder size. Furthermore, in order to verify the proposed stress-strain curve for concrete cylinders, six cylindrical specimens were tested. Comparisons between the observed and calculated stress-strain curves of the tested cylinders showed reasonable agreement. 碕悒 瀀 ꀏ 會Ā ﾖ⨀ 頊㪡 Ā ᐀ 會Ā᐀ 䢘ﾖ⨀ 》㪡 Ā 㰀 會Ā㰀 ꂘﾖ⨀ 젋㪡 Ā ㈀ 會Ā㈀ ﾖ⨀ Ā ᐀ 會Ā᐀ 備ﾖ⨀ 術 Ā ᐀ 會Ā᐀ ꢙﾖ⨀ ⁔ Ā 저 會Ā저 ﾖ⨀ ꢖ悒 Ā 저 會Ā저 墚ﾖ⨀ ᣅ쾡 ഀ Ā 저 會Ā저 낚ﾖ⨀ 냅쾡 Ā 저 會Ā저 ࢛ﾖ⨀ 炀ᦰ Ā 會Ā 悛ﾖ⨀ ࢁᦰ 㘀 Ā 切 會Ā切 뢛ﾖ⨀ ႖悒 Ā 搀 會Ā搀 ႜﾖ⨀ 룆抓 Ā 저 會Ā저 梜ﾖ⨀ 僇抓 Ā 저 會Ā저 삜ﾖ⨀ 塲얦 ࠀ Ā ࠀ 會Āࠀ ᢝﾖ⨀ 얦 Ā 저 會Ā저 炝ﾖ⨀ 衳얦 ሀ Ā 저 會Ā저 좝ﾖ⨀ 抓 瀀 ꀏ 會Ā ﾖ⨀ ¦麩 Ā Ā Ā 會ĀĀ 碞ﾖ⨀ 颦麩 Ā Ā Ā 會ĀĀ 킞ﾖ⨀ 㾜 Ā Ā Ā 會ĀĀ ⢟ﾖ⨀
