Abstract:
This study evaluates the accuracy of building performance metrics
calculated with nonlinear numerical models created based on the
provisions in the ASCE 41 and ACI 369.1 standards. The evaluation
was based on a seven-story non-ductile reinforced concrete
building located in Van Nuys, CA, instrumented and severely
damaged during the 1994 Northridge Earthquake. The purpose of
the evaluation is to validate the computed system-level response of
nonlinear models created with modeling parameters in ASCE 41/
ACI 369.1. The study also evaluates the effect of Rayleigh damping
parameters and joint modeling approach on the accuracy of building
performance metrics. It was found that ASCE 41/ACI 369.1 models
provided a reasonable representation of building response, with
error indexes for displacement signals ranging between 0.28 and
0.40, although the error range was higher than those achieved by
other researchers by optimizing modeling parameters outside the
provisions in the ASCE 41/ACI 369.1 standards.
