Analysis methods for calculating structure internal forces by subinterval method are investigated. Some methods for solving structure accelerations are derived. The principle of calculating the structural dynamic response by single-step time-element-Tailer method is presented. In comparison with the step-by-step integration algorithm, example shows the method introduced in this paper gives numerical results with much higher accnracy.
