Effects of the 1985 Earthquake in Lazaro Cardenas, Mich.
An account is presented of a geotechnical survey made shortly after the major earthquake of September 19, 1985 (magnitude 8. 1) at the industrial port of Lazaro Cardenas in the state of...
Earthquake Response of La Villita Dam
Due to the recent industrial and housing developments at the port of Lazaro Cardenas, located 13 km (8 miles) downstream of La Villita Dam, at the mouth of the Balsas River, the hazard...
Analyses of Foundation Failures
During the earthquake of September 19th, 1985, many buildings tilted and underwent settlements, sometimes of very large magnitudes. This paper describes and analyzes these settlements....
Soil-Structure Interaction in Mexico City During the 1985 Earthquakes
The effects of the flexibility of the soil and the foundation on the seismic response of structures, by opposition to clear foundation failures, cannot be easily identified from a simple...
Performance Characteristics of Structures, 1985 Mexico City Earthquake
The 1985 Mexico City earthquake caused major damage to buildings, but not other structures, in the center of Mexico City, located approximately 400 km. from the epicenter. Due to soil...
Preliminary Dynamic Analyses of the Ministry of Agriculture Building
The Ministry of Agriculture building on Avenida San Antonio Abad was originally constructed as a 17 story reinforced concrete structure using a waffle slab system with interior reinforced...
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...
R/C Frame Drift for 1985 Mexico Earthquake
This paper contains the results of a parametric study of the displacement response of multi-story reinforced concrete frames. Nonlinear lateral displacement responses were calculated for...
