Lessons from Dam Incidents. US-II
The purpose of this report is to present available data to the profession regarding failures, accidents, and major repairs at dams in the United States. Data is analyzed with respect to...
What really happened at L'Ambiance Plaza
Even though the National Bureau of Standards has issued its report on the probable cause of failure in the collapse of the L'Ambiance Plaza. there is room for doubt as to...
Computer Assisted Mistakes
The proliferation of computer usage by design engineers will continue to generate change in practice. It will affect the process and production of design. It will affect the relationships...
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...
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,...
Stopping Seepage
The Navajo Dam in New Mexico has major seepage problems. The Bureau of Reclamation, which owns the Dam, conducted studies, verified by outside consultants, concluding that the combination...
St. George Harbor?A Berm Breakwater Solution in Alaska's Bering Sea
The berm breakwater concept is based on the premise that locally available materials should be used in breakwater construction to the largest degree possible. By looking at failure dynamics...
Natural Stabilization of an Eroded Permafrost Site
The paper referred to in this abstract discusses the erosional processes during and after the initial failure, proposed solutions to repair and stabilize the site, and details of the performance...
Building Around a Building
Many, maybe most, construction disasters occur as the result of the failure of temporary structures. Despite the fact that temporary structures have a critical effect on the speed, safety...
California's Fourteen Years of Coastal Zone Management
California's Coastal Zone Management Program has been considered the flagship of the nation; yet large questions remain as to whether the program can protect California's...
Hazardous Waste Landfill Cap System Stability
Pursuant to the regulatory requirements for control of rainfall infiltration into a hazardous waste landfill, a cap design that is impervious plus stable is required. The intent of a cap...
Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....
The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...
Investigating Failure
Failure investigations can be adversarial or cooperative, but impartiality, good engineering ethics, and professional responsibility require that the investigator begin with no premature...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
Verification of a Generalized Mudflow Model
This paper presents the results from recently completed studies verifying the accuracy and applicability of a generalized one-dimensional model for dynamic routing of mudflows. Numerical...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
