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,...
Performance of Steel Structures
A description of the various types of steel structures built in Mexico City is made, including comparisons of the older types of steel construction with more modern buildings. Performance...
Damage Assessment and Seismic Behaviour of Steel Buildings in Mexico City
Preliminary reports on the September 1985 earthquakes indicated 10 steel buildings collapsed and 2 more severely damaged. The total number of buildings found either collapsed or severely...
