This paper studies a method to identify the elastic fixed stiffness of the frame structure. The model of the problem is three dimensionals structure, linear elastic deformation, pile - soil link is replaced by elastic fixed with stiffness. The problem will be solved by the penalty function method - the minimum of the objective function (which is the total squared error between the measured value and the calculated values particular) - combined with the finite element method. The numerical calculations show that the model, algorithm and calculation program are reliable. The program can be used to identify the elastic fixed stiffness of the frame structure in three dimensions, serving to determine the actual working state of the structure, to propose solutions for reinforcement, repairing, improving bearing capacity, prolonging the life of the structure.
