In performing the dynamic analysis, the step size used in a step-by-step integration methodmight be much smaller than that required by the accuracy consideration in order to capture the rapidchanges of dynamic loading or to eliminate the linearization errors. It was first found by Chen andRobinson that these difficulties might be overcome by integrating the equations of motion with respect totime once. A further study of this technique is conducted herein. This include the theoretical evaluationand comparison of the capability to capture the rapid changes of dynamic loading if using the constantaverage acceleration method and its integral form and the exploration of the superiority of the timeintegration to reduce the linearization error. In addition, its advantage in the solution of the impactproblems or the wave propagation problems is also numerically demonstrated. It seems that this timeintegration technique can be applicable to all the currently available direct integration methods.
