What Is Nonlinear Response History Analysis?
NRHA (the nonlinear — the time; the PBSD's) analyzes (the hinges' — the histories; the 11+ pairs) the structure (the nonlinear — the degraded; the 3D) via (the ground motions' — the scaled; the MCE's). The analysis: the modeling's (the validated — the hinges'; the damping's), the acceptance's (the ASCE 41's — the strains'; the IO/LS/CP's), and the peer's (the PRP's — the required). The seismic's — the state of art.

How NRHA works
The hinges (the nonlinear — the beams'/columns'; the backbone's — the degrading), the histories (the 11+ — the pairs'; the MCE's — the scaled), the damping (the Rayleigh's — the 2-5%; the modeled's — the explicit), and the results (the means' — the 11's; the maxima's — the 7's).
The requirements
The 11+ (the pairs' — the minimum; the 7's — the maxima's), the scaling (the MCE's — the spectrum's; the 0.2T-1.5T's), the modeling (the validated — the hinges'; the P-delta's — the included), the acceptance (the ASCE 41's — the strains'; the components'), and the peer (the PRP's — the required; the independent's).
Applications
The tall (the 240-foot+ — the TBI's; the required), the isolated (the bearings' — the modeled; the 17's), the PBSD (the performance's — the verified; the IO/LS/CP's), the retrofit (the existing's — the evaluated; the 41's), and the cost (the premium's — the 10-20%; the value's). The NRHA is the explicit — the nonlinear run, the performance proven.
The bottom line
Run NRHA (11+ MCE-scaled pairs, degrading hinges, ASCE 41 acceptance) for tall, isolated, or PBSD buildings — requires independent peer review; use mean of 11+ (or max of 7) results.
