在进行动力分析之前，本文考虑了与结构静自由度减少有关的误差。结果表明，对于受迫振动问题中计算的构件载荷，标准的减振方法会产生很大的误差。提出了一种改进的约化方法，该方法可以显著降低误差。标准方法和修改后的方法适用于悬臂梁、门式框架和管道系统。
This paper considers the errors associated with the reduction of the structural static degrees of freedom before performing a dynamic analysis. It is shown that the standard methods of performing the reduction can lead to significant errors especially for the member loads computed in a forced vibration problem. A modified reduction is developed which is shown to significantly reduce the errors. The standard and modified methods are applied to a cantilever beam, a gabled frame, and a piping system.
