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...
Comparison of Predicted and Measured Dynamic Behavior of Allied Bank Plaza
Structural engineering aspects of a monitoring program to measure Allied Bank Plaza tower's dynamic response to wind are presented. In particular, field data developed during...
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...
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...
Soil Quality Testing in Ports: Why?
The Port of Seattle has instituted an agency-wide environmental protection guidelines which include the option to prepare site histories and perform chemical screening of soils prior to...
Design Concepts for Floating Breakwaters
This paper describes a fundamental approach to the design of a floating breakwater based on the concepts of dynamic analysis of floating bodies. The process results in a relatively simple...
Geotechnical Aspects of Waterfront Parks: Case Histories
This paper presents several case histories of waterfront developments, and describes the general approach that the geotechnical consultant should take in the design of these projects....
Puget Sound Alluvium: A Challenge in Design of Pile Supported Port Facilities with Dredged Slopes
The geotechnical investigation, evaluations, and recommendations for the Port of Seattle Terminal 18/20 Improvement Project are described and compared with observed performance during...
Overdredging at Existing Gravity Structure
Pacific Elevators Ltd. decided to upgrade Berth No. 2 to handle ships up to 70,000 DWT. The difficulty was to maintain the support of the cribs after dredging of the berth to minus 45...
Underwater Compaction of Sand Fill During Placement
A system and related equipment have been developed, and tested on a recent dredged fill project, to compact sand, either clean or with limited silt, in lifts several feet in thickness...
Seismic Design of Earth Retaining Wharf Structures
Seismic design considerations pertinent to earth retaining wharf structures are reviewed. These considerations include: evaluation of the seismic environment and design earthquake ground...
Soil-Structure Interaction in Seismic Environments
Soil-structure interaction depends on the mass, stiffness and the damping of the structure as well as on the geometry and embedment of the foundation and on the properties of the soil....
Recent Advances in Structural Dynamics
The four papers in this book emphasize the design, testing, and analysis of large structures. The topics covered include base isolation in the design and construction of power plant structures,...
Dynamic Response of Structures
The primary goal of the third specialty conference on the dynamics of structures was to provide a forum for dialogue between engineers conducting experimental tests and those developing...
Building Motion in Wind
The trend towards higher structural efficiency and hence lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation...
Geotechnical Aspects of Stiff and Hard Clays
This publication contains articles that deal with field and laboratory measurements of engineering properties of stiff (overconsolidated) clays, and comparisons of predicted and measured...
Settlement of Shallow Foundations on Cohesionless Soils
Design and Performance
The main objectives of this book are to present some of the available techniques for estimating the settlement of shallow foundations on cohesionless soils, and to compare predicted and...
