在这项研究中，提出了一个新的设计公式预测单调加载外梁柱节点的抗剪强度。为此，几个关键变量的行为的梁柱节点的影响进行检查使用的参数研究的结果编译从大量的外部联合测试的实验数据库。所建议的设计方程与以前提出的方程有三个不同之处。首先，该公式考虑了梁纵筋配筋率的影响，这是以前建议的设计公式中没有考虑的。其次，由于考虑了该参数的影响，得到了对接头纵横比影响的更真实的估计。第三，对于低、中、高三种配箍率的节点，在某种程度上考虑了箍筋的影响，这在以前的公式中是没有考虑的。结果表明，所提出的设计公式能以最小的标准差准确地预测外梁柱节点的抗剪承载力，比已有的设计公式更可靠。(C)2002爱思唯尔科技有限公司版权所有。
In this study a new design equation for predicting the shear strength of monotonically loaded exterior beam column joints is proposed. For this purpose, the influence of several key variables on the behaviour of beam-column joints are inspected using results of parametric studies on an experimental database compiled from a large number of exterior joint tests. The design equation suggested has three differences from the previously proposed equations. First, the equation proposed considers the influence of beam longitudinal reinforcement ratio, which was not taken into account in previously suggested design equations. Second, as the influence of this parameter is taken into account, a more realistic estimate of the influence of joint aspect ratio is obtained. Third, the influence of stirrups is considered differently for joints with low, medium and high amount of stirrup ratios, in a way, which was not considered in previously suggested equations. The results showed that the proposed design equation predicts the joint shear strength of exterior beam column connections accurately with minimal standard deviation and is more reliable than the previously suggested equations.
