摘　　要：在现有的灵敏度遗传算法的基础上,采用现有的节点损伤模型,以单元的节点固结系数为待识别变量,进一步将该算法应用于框架梁柱连接刚度识别。算例分析结果表明,灵敏度遗传算法与常规遗传算法相比,具有更高效率和精度。The existing sensitivity genetic algorithm is used to identify the connection stiffness of frame structures. The coefficients of joint concretion of existing joint damage model are used as the variables for identification. According to the results of example, the sensitivity genetic algorithm was more effective and accurate than the conventional genetic algo-rithm.
