| Abstract: | The discussed paper explores how various assumptions for damping and geometric nonlinearity affect the seismic collapse behavior of steel‐frame buildings. The recommended damping scheme is questioned, and an alternative is suggested. Additional explanation is sought to justify the differences observed between the P‐delta and co‐rotational models for geometric nonlinearity. Copyright © 2016 John Wiley & Sons, Ltd. |
