摘要
En 中文
Single parametric hermitian finite difference operators are employed to derive an unconditionally stable one-step direct integration algorithm family for structural dynamic equations. Accuracy is considered in terms of local truncation error and exponential truncation error corresponding to the period dispersion, numerical damping and spectral radius, This algorithm family presents computational effort similar to Newmark's method for the lumped model.
