陳德文 (南京市民用建筑設(shè)計研究院 210004)[提要] 通過九根高強鋼筋高強混凝土梁的受彎試驗研究,提出了既反映高強混凝土的特性、又與現(xiàn)行混凝土結(jié)構(gòu)設(shè)計規(guī)范GBJ10-89銜接的抗裂度及裂縫寬度的計算方法。
[關(guān)鍵詞] 高強混凝土 抗裂度 裂縫寬度Through testing nine high-strength concrete beams reinforced with high-strength bars, we proposed a method to calculate the crack-width of high-strength concrete beam with high-strength bars, which not only represents the characteristics of high-strength concrete but also joins up with the Code of Concrete structure( GBJ10 - 89).
Keywords: high-strenghth concrete; crack resistance; crack-width
