【摘要】 本文对一个四层钢框架连接损伤进行数值模拟,比较了两种改进算法的测试结果,即阈值和权值同步学习BP算法(改进算法2)以及L-M算法(改进算法1)。从而证明了改进算法2更精确、更优越。更多还原

【Abstract】 In this paper,through numerical veritification on connection damage of a four-story steel frame,the test results of two kinds of improved BP algorithms,which are BP algorithm with weight and threshold synchro-learning ability(shorted for improved BP algorithm 1) and Levenberg-Marquardt algorithm(shorted for improved BP algorithm 2) are compared.As a result,it is proved that the improved BP algorithm 2 is more accurate and more superior.更多还原
