[提要]  通过九根高强钢筋高强混凝土梁的受弯试验研究，提出了既反映高强混凝土的特性、又与现行混凝土结构设计规范GBJ10-89衔接的抗裂度及裂缝宽度的计算方法。
[关键词]  高强混凝土 抗裂度 裂缝宽度

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
