Abstract
This technical note aims to investigate the accuracy of the so-called Coefficient Method included in the ASCE/SEI 41-17 standard for estimating the maximum (target) roof displacement demands in reinforced concrete frames subjected to pulse-like near-fault earthquake ground motions. Additionally, enhanced coefficients C1 and C2 introduced in the literature to be used in the Coefficient Method were also included in this investigation. Results obtained from this study reveal that the current coefficient C1 included in the ASCE/SEI 41-17 standard leads to a standard error larger than that when enhanced coefficients are employed. Particularly, this observation is attributed to the limitation of current coefficient C1 to capture the empirical spectral trend when structures are subjected to pulse-like near-fault earthquake ground motions.
