RODRIGUEZ, Mario E.  e  RESTREPO, José I.. Práctica y diseño sísmico de edificios en México - cambios necesarios. Ing. sísm [online]. 2012, n.86, pp.89-118. ISSN 0185-092X.

Seismic design provisions given by the 2004 Mexico City Building Code (MCBC) are reviewed in this paper. To improve these provisions, and based on recent research findings, changes for some of these provisions are proposed. The paper proposes improving the definition of current seismic design spectra, to lead to rational and transparent seismic design procedures. It is shown that changes are needed in the MCBC procedures for prohibiting the use of structures with insufficient lateral deformation capacity, and for appropriate evaluation of lateral stiffness of structures in order to avoid the overestimation of this stiffness, as well as for better seismic design procedures of diaphragms and appendixes.

Palavras-chave : earthquake resistant design; design spectra; connections in precast structures; lateral stiffness; horizontal floor accelerations; diaphragms.
