收集了国内外文献中的345根集中荷载作用下有腹筋梁的剪切破坏试验数据,将所有试验梁的试验结果与我国规范GB50010-2002、美国规范ACI318-05、欧洲规范EC2-02以及Zsutty公式的预测结果进行比较,分析各计算方法的优缺点,以及对各抗剪承载力影响因素的考虑是否得当。结果表明:Zsutty方法的预测结果最为精确,其次是我国规范GB50010-2002方法,美国规范ACI 318-05和欧洲规范EC2-02的预测结果比较保守;四种预测方法的对于纵筋配筋率小于1%的梁、有效高度较大的深梁,预测结果安全度偏低。
Collected data of 345 domestic and foreign concentrated load under the effect of the web reinforcement beam shear failure test data, the test results of all the test beams and our standard GB50010-2002, the United States Code ACI318-05, the European Code EC2-02 and Zsutty Formula predictive results are compared to analyze the advantages and disadvantages of each calculation method, as well as the factors that affect the shear strength of the appropriate consideration. The results show that the prediction results of Zsutty method are the most accurate, followed by China’s standard GB50010-2002 method, the prediction of the American Standard ACI 318-05 and the European standard EC2-02 is conservative. The prediction rates of the four methods are less than 1% of the beam, the effective height of the deep beam, the forecast result of low security.
