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...
Electronic Computation
The papers included in this book were presented during the thirteen sessions of the Ninth ASCE Conference on Electronic Computation. Topics addressed represent a wide spectrum of computer...
Financial Analysis of Port Facilities
This paper describes a spreadsheet-based structure for financial analysis of port facilities and services, designed for use as a planning tool by non-specialist port managers. The paper...
Port Master Plans and Feasibility Studies
Port projects are cost-intensive long-life irreversible assets, and developing countries particularly limping with resource constraints could not afford the luxury of short-sighted defective...
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...
Marina Design and Environmental Concern
Research initiated by a Florida Cabinet Resolution of August 6, 1974, has generated two models for the evaluation of the impact of marina development on coastal waters. One, a complex...
Port of Long Beach Supertanker Terminal
The supertanker marine terminal and crude-oil transfer facility at Berth 121 on Pier E in the Port of Long Beach, California is the largest tanker-handling berth on the West Coast. This...
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....
Modern Inspection Techniques n Port Maintenance
This paper addresses inspection of underwater structure of port facilities to acquire information which, when subjected to engineering analysis and confirmation, allows planning of short...
Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...
Los Angeles and Long Beach Harbors Tidal Circulation Study
Expansion of harbor facilities frequently involves placement of additional landfill and the deepening of channels and mooring areas. A numerical tidal circulation model was used in the...
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...
Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....
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...
