| 摘 要： | 提出了一种构造高精度无条件稳定的积分格式方法，建立了具有三阶精度的无条件稳定直接积分法，既适用于比例阻尼体系，也适用于非比例阻尼体系。与以往的高精度方法相比，本文方法具有计算量少、存贮空间小的优点，而且没有超越现象。

| Abstract: | In this paper, a method for developing high accuracy unconditionally stable integration schemes is presented; a third-order accuracy unconditional stability algorithm is developed, which can be applied to the dynamic analysis of proportionally and non-proportionally damped structures. The high accuracy method developed herein has an advantage of fewer calculation and storage over the former high accuracy methods, and no overshoot. |

| Keywords: | high accuracy direct integration method unconditional stability proportional damping non-proportional damping overshoot |
