Abstract To damp out spurious high‐frequency responses, time‐step integration algorithms for structural dynamic analysis should have controllable numerical dissipation in the regime. The also be unconditionally stable so that size is governed by accuracy requirement only. This paper reviews several recently developed frameworks can used to construct dissipative algorithms. continuous displacement (single‐field) formulations are considered here. algorithmic parameters control discussed.
