梁柱外伸端板连接初始刚度计算模型的验证及修正建议
est and correct advice for the initial stiffness formula of extended end-palte beam-column connections
针对梁柱外伸端板连接节点，给出现有的初始刚度计算模型，从理论上分析了现有计算模型的不足之处，然后通过试验数据验证其准确性，得出该模型能较准确地反映构造参数和初始刚度的关系，但同时存在一定的误差，需进行修正。然后，利用ANSYS模拟，得到和实际试验比较吻合的结果。最后给出对该模型的修正建议。
his paper is concerned with initial stiffness formula of extended end-palte beam-column connections.The disadvantages of the formula are discussed.Compared with the test results，the formula reflects the relationships of constitution parameters and initial stiffness almost turely，but some corrections are needed.By means of ANSYS simulating, better results are abtained.At last, some advice are provided on correcting the formula..
