Geotechnical Notes on the Effects of Mexico's 1985 Earthquakes
The present notes briefly describe the most relevant effects of the September 19 and 20, 1985 earthquakes on shallow and deep foundations used in Mexico City, which is located at about...
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....
Seismic Design Criteria for Foundations on Control Piles
Control piles have been widely used in Mexico City for underpinning buildings with excessive settlements caused by the consolidation of the soft clay deposits, and as a foundation solution...
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...
Burying the Nuclear Past
The Uranium Mill Tailings Remedial Action Program involves reclaiming 24 tailings piles. The work is done in terms of Federal Legislation to prtect the environment and people from the...
Bridge Design By 1-2-3
MULTBEAM, a Lotus 1-2-3 template, can be used to analyze simple-span, multigirder steel highway bridge superstructures. Since it was developed for in house use by Sverdrup Corp., this...
Crossing A Freeway
The Washington State Convention and Trade Center in Seattle is being constructed on air rights spanning Interstate-5, adjacent to the seven acre Freeway Park that also spans the highway....
Pressure Injected Footings in Piedmont Profiles
Comparatively little has been published on the behavior of pressure injected footings in the Piedmont residual soils and weathered rocks. It is the purpose of this paper to describe some...
Construction of Fisherman's Wharf Breakwater
The San Francisco District of the United States Army Corps of Engineers recently completed construction of a breakwater at Fisherman's Wharf. The construction, completed ahead...
Shoreline Development in Southern Lake Michigan
This abstract refers to the effect that record-high lake levels, shoreline erosion, and the decline of the steel industry are having on present and future plans for shoreline development...
Steel Boxes Carry Rail Lines
Steel box girders plus novel bearing details led to beautiful curved bridges carrying Chicago Transit Authority trains into its Howard Yard. During preliminary design three alternative...
Strengthening Old Floors
The floors of the historic City Hall and Courthouse in Minneapolis had withstood 80 years of hard use before they have to be analyzed and brought up to code. The building is about 300...
The Chicago Lakefront Plan - 1986
Although Chicago is considered to have one of the world's most beautiful and also stable waterfronts, much of its shore protection is in imminent danger of failure. Nearly...
Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...
Structural Engineering and Microcomputers
This publication contains five papers on the use of microcomputers by structural engineers. The first paper discusses the design of multi-story rigid steel frames. The design process employed...
Effects of Damage and Redundancy on Structural Performance
There are numerous factors involved in the interrelationship between damage states, redundancy, system strength and structural performance. This volume examines some of these factors and...
Foundations for Transmission Line Towers
This special technical publication contains the proceedings of a two session symposium on foundations for transmission line towers. These papers were written by researchers, geotechnical...
Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...
