| Abstract: | In December 1976 the new version of Mexico's Federal District Building Code was officially approved. It differs from previous versions in several matters: design values are based on a probabilistic assessment of seismicity, on a more careful and better substantiated consideration of wave filtering through the peculiar lacustrine soil and on approximate design optimization; ductility receives explicit treatment; and there are significant improvements in the treatment of overturning moments, torques, etc. The paper discusses these matters and contains information on code evolution in Mexico and on the implementation in the Federal District. |
