WebOct 19, 2024 · Computed horizontal accelerations considering the Taft Record acceleration have a similar behavior with regards to linear analyses. Results show that accelerations at heel approximately match the free-surface Taft Record while horizontal accelerations at crest are substantially greater (amplified), mostly between \(t = 4\) and \(t = 14\) s. WebMNGP was designed using the safe shutdown earthquake (SSE) ground response spectrum (GRS) which was derived from the North 69-degree West component time history of the 1952 ... West component time history of the 1952 Taft earthquake, normalized to a 0.12g PGA as the base input motion. A conservative 3 percent damping ratio was used in the …
