Based on solving the Hamiltonian system and transfer matrix method, the proposed mega-frame structure analysis of the calculation model, the model in the mega-frame calculation is a simple, versatile. Floor rigid handle, load floor elevation at. A frame column and framework beam calculated separately connected to a flexible approach. The two framework is seen as the main frame of the elastic foundation, making the model more in line with the actual structure. The giant frame building structure calculations, a framework for the sectional dimensions of beams and columns, assumed the structure of the majority of the force, as the main lateral force resisting members. Two frame beams, the smaller size of the column, only play a supporting role, as well as the components of the energy consumption in the earthquake. Is also responsible for the floor at the vertical load transfer to the main frame. Through the secondary framework for the continuous treatment, and regarded as a a giant shaped frame structure unit elastic foundation, to ensure the usefulness and accuracy of the model. Giant frame beams, the potential energy of the column unit strain and elastic foundation elastic strain energy potential external force and external loads were calculated by Timoshenko beam theory. Expression of the total potential energy of the mega-frame structure, deduced the combined Lagrangian function expression, derived from the Hamiltonian, Symplectic system of control equation the megaframe Hamiltonian dual equation. The step-by-step integration of the extended state vector and the expansion of the state transition matrix can have a giant frame beam column transfer matrix. Calculated using precise integration method for solving boundary value problems at both ends, thereby seeking to get the high-precision numerical solution. Used analysis methods borrowed the Hamiltonian solution system, the numerical solution convergence, stability, convergence, speed, high precision. Based on the preparation of this article formula corresponding MATLAB program to facilitate for the calculation of the preliminary analysis of the structure. Provides a more accurate basis for the determination of such structural design program and preliminary design calculations. In this paper, the stress analysis of the new set of mega-frame structure, and the preparation of the corresponding MATLAB program. And through the analysis of specific examples, and compared the results with literature, which verifies this study the feasibility and reliability of the analysis the giant frame by force, and the pros and cons of the mega-frame structure calculation model and make of the scope of the relevant judge .
