WebMay 10, 2013 · SAP 2000 with Hilber-Hughes-Taylor α direct integration method is used for Non-linear Time History Analysis (NL-THA). Seismic Modeling is discussed in this paper. Then six sets of acceleration time histories are used for NL-THA by SAP 2000. WebHilber, Hughes, and Taylor (1978) present cogent arguments for the use of Equation 2.4.1–2–Equation 2.4.1–4 for integrating structural dynamics problems. The main appeal of the operator is its controllable numerical damping and the form this damping takes, slowly growing at low frequencies, with more rapid growth in damping at high frequencies.
