摘要
本文对采用显式Ｎｅｗｍａｒｋ法的拟动力实验方法进行了分析，指出欠调和超调两种主要的系统误差对实验结果的影响，提出了采用人工阻尼抑制误差增长的方法，对于输入是ＥＬ－ＣＥＮＴＲＥ地震波的数值分析结果表明，这种方法具有很好的效果．
In this paper, the effects of undershoot and overshoot on the testing results have beenanalyzed in terms of the explicit Newmark method in a psuedodynamic test.An artificialdamp method is used to restrain the error growth.With EL-Centro earthquake wave,numerical,examples show that the artificial damp method is effective.
