Implications of Structural Characteristics on Failure
Performance of buildings with two common structural types, many of which suffered heavy structural damage or collapse, are analyzed. Conclusions are drawn that no structural type is inadequate,...
Observations on Structural Pounding
In over 40% of the collapsed or severely damaged buildings in Mexico City, pounding of adjacent buildings occurred, and in at least 15% was the primary cause of collapse. The main objectives...

Emergency Regulations and the New Building Code
The 1942 Federal District Building Code was crude and overoptimistic. The 1957 earthquake prompted the drafting of emergency regulations, modern and more realistic. They evolved into the...
Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...
Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...
