Short summary
Seismic design guidelines for building structures present simplified approaches to include relevant structural behavior that affects the structural response through design spectra modification factors. The objective of this study is to propose simplified mathematical expressions to modify the design spectra to consider the stiffness and strength-degrading behavior of structures. Additionally, these expressions are proposed to be included in the next version of the Mexico City Building Code.
