According to the hypothesis of continuum, a tube with the corner strengthened is gained to make an equal of the frame-tube. B3-spline functions and parabola functions are applied to simulate the displacement functions of the frame-tube. The system of equations about the undetermined coefficients of displacement functions is deduced by using energy-variational principle, by solving which the displacement of the frame-tube is gained. Then the internal forces in the columns and beams of the former frame-tube are obtained according to the principles of elasticity mechanics.

For a long time,there have existed in China a flexibility in the town planning,a tendency toward decentralization,urban expansion by the aggregation of fixed units,the mobility and prefabrication of buildings,and the use of a precise standard-the 'chien',the basic unit of construction derived from the width of the central beam.
