Based on the basic ideas of finite element method, the high-order huge discrete element method is introduced in for analysing the tall and multiple-bay frame structures which are obviosly discrete structure systems. Using this method the number of unknown quantities can be greatly reduced, thus saving the calculating time and storage space of a computer. In this method the num bcr of unknown quantities has no direct relation to the number of the storeys and bays of a frame structure. The greater the frame structures is; the more advantageous the method and the more accurate the results will be.
