Pressuremeter and Shallow Foundations on Sand
The settlement and bearing capacity rules for the design of shallow foundations on sands using the results of pressuremeter tests are reviewed. The results of four footing tests to failure...
Structural Settlements at a Major Power Plant
The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests,...
Experimental Studies, Structural Design and Full-Scale Measurements for the Columbia Seafirst Center
The Columbia Seafirst Center is a 76-story office tower located in downtown Seattle, Washington. It rises to a height of about 940 feet above ground and is the world's 10th...
Damping in Tall Buildings: Its Variability and Treatment in Design
Increasingly, damping is being recognized as an important factor in the design of structures. It is at the same time a property which is relatively poorly defined, more acquired than engineered...
Damping Systems to Limit the Motion of Tall Buildings
Two types of damping systems have been used successfully in building applications - the Tuned Mass Damper, and Viscoelastic Damping Units. In the past, Tuned Mass Dampers were used in...
Design of Viscoelastic Dampers for Columbia Center Building
To reduce the dynamic response of a building with a given height and plan area to wind load, aside from inherent damping of the building, the designer has a few options available to him/her....
Performance of Viscoelastic Structural Dampers for the Columbia Center Building
Vibratory motion of structures such as buildings, bridges, and floors can be reduced by the use of viscoelastic (V. E. ) dampers. Such dampers transfer part of the vibratory energy of...
Blasting Densifies Sand
Constructing the Jebba Dam on Nigeria's Niger River required in-place densification of large volumes of loose sand to record depths of up to 131 ft. Vibrocompaction was used...
Complex Tower Meets Quake Code
A Los Angeles building consists of a triangular 23-story office tower stacked on top of an 11-story rectangular parking garage. The dual-shape is unique in seismically active southern...
Computer Cuts Tower Steel
Two computer programs developed by Lev Zetlin Assoc., New York City, revealed that some of the steel in what will be Philadelphia's tallest building, One Liberty Place, was...
Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...
Berth 5-6 Pavement Performance: Port of Oaklan
In 1978 the Port of Oakland commenced a project to demolish the old Berth 5, 6 & 7 break bulk sheds, portions of the wharves, and the warehouses behind, and to construct container...
Pavement Design for a Break Bulk Terminal Yard
This paper discusses the practical application of mechanistic pavement design principles for a proposed 8. 1 ha break bulk cargo storage yard that is part of the Port of Portland's...
Concrete Block Paving for Marine Terminals
This paper describes the application of concrete block pavements to marine terminals. The Corps of Engineers flexible pavement design approach can be modified to provide a conservative...
Roller Compacted Concrete Pavement for Marine Terminals
This paper describes recent intermodal yard paving projects at the Port of Tacoma, Washington which have utilized a relatively new paving process known as Roller Compacted Concrete (RCC)....
An OCEANWHEEL Breakwater
The compression wall and tension spoke structural system (OCEANWHEEL) transfers lateral loads from sea surface to seafloor efficiently. It promises a wide variety of uses beyond the described...
Tacoma Terminals Pier Designed for Economy
This pier is a representative and highly refined sample of what is known as the Puget Sound system of construction, an economical system that maintains the durability necessary in the...
Carnation Terminal, Oakland?Preliminary Design
The Preliminary Design process is examined as it was applied to design of wharves for a new container terminal in the Port of Oakland, California. The process includes active interdisciplinary...
Siltation of the Port of Astoria
Sedimentation rates suddenly increased in the Port of Astoria, Oregon, immediately following the May 18, 1980 ash eruption of Mt. St. Helens. This ash was transported down the Columbia...
