［摘要］建立了一个包含259个矩形截面钢筋混凝土剪力墙的试验数据库，将数据分类筛选后与中国《高层建筑混凝土结构技术规程》（JGJ 3—2010）、美国规范ACI 318-11、新西兰规范NZS 3101∶2006以及欧洲规范Eurocode 8的抗剪承载力公式进行对比。结果表明，各规范抗剪承载力公式的计算结果与试验实测结果的比值离散性均较大，中国规范JGJ 3—2010和美国规范ACI 318-11的抗剪承载力公式较为安全准确，欧洲规范Eurocode 8抗剪承载力公式最为离散。经分析发现，对于上述四种规范，抗剪承载力公式中混凝土部分抗剪公式过于保守和不准确是导致整个抗剪承载力公式离散性较大的一个重要原因。在中国规范JGJ 3—2010的抗剪承载力公式的基础上，基于数据库对混凝土部分抗剪公式进行调整，调整后的抗剪承载力公式的准确性比原有公式有明显提高。

Abstract:An experimental database of 259 rectangular section reinforced concrete shear walls was established. The data were classified and screened and compared with the shear capacity formulas of Chinese Technical specification concrete structures of  tall building (JGJ 3—2010), American code ACI 318-11, New Zealand code NZS 3101∶2006 and European code Eurocode 8. The results show that the ratio of calculation results of shear capacity formulas in various codes to actual test data are quite discrete. The shear capacity formulas in Chinese code JGJ 3—2010 and American code ACI 318-11 are relatively safe and accurate, while the shear capacity formulas in European code Eurocode 8 are the most discrete. Through analysis, it is found that for the above four codes, the shear formulas of concrete part are too conservative and inaccurate, which is one of the important reasons for the large dispersion of the whole shear capacity formula. Based on the shear capacity formula of Chinese code JGJ 3—2010, the shear formula of concrete part was adjusted based on the database. The accuracy of the shear capacity formula is significantly improved compared with the original formula.
