A METHOD OF DISTRIBUTION OF DEFORMATION MATRIXES——THE METHOD OF LITTE MATRIXES FOR THE ACCURATE SOLUTION OF CONTINUOUS ARCH AND THE APLICATION TO DESIGN OF CONTINUOUS ARCH BRIDGE

In this paper C. V. Kloucek's method of distribution of deformation is extended from that there is only one node displacement to that there are two displacements at a node. We use matrixes of two orders (little matrixes) to indicate displacements, transmission coefficients as well as all the appropriate puanfities. After arranging and beriring we obtain the same forms with the method of distribution of deformation, then the signals in the formulas are not numbers but matrixes of two oders. After that an accurate solution of a continuous arch is presented. Combining "The manual of design of arch bridge" we are able to calculate the continuous arch bridge. In the end of the paper an engineering example isg iven and the result is satisfactory.
