Based on a stability characteristic equation of the elastic supported column,this paper deals with the study on stability computation of liner elements structure.A simple computational method for critical load is suggested.The main points of this method are as follows:first,to establish a suitable model for elastic supported column;second,to calcu- late the equivalent rigidity coefficients of the elastic supported column.The examples show that this method is more reliable,more simple,and has clearer physical meaning than other methods.
