Abstract: A discriminance method was proposed to identify the element with concentrated load,which was judged by the geometrical relationship between the abscissa,vertical coordinates of load point generated from genetic algorithm(GA) and four edges of every element.Furthermore,the load was allocated to nodes of the element by the equivalent distribution principle.Finally,the location of arbitrary concentrated load was identified by finite element analysis and the superior global search capacity of GA.Compared with the identification methods of neural network and inverse finite element analysis method.The presented method is able to identify the concentrated load locating at the interior of a element,and the numerical examples show that this method has higher accuracy.
