Response of the San Juan Bautista 156/101 Bridge to the 1979 Coyote Lake Earthquake
Strong-motion accelerograms are used to examine the response of a multiple-span highway bridge to earthquake loading. Estimates of modal frequencies and damping values for the first two...

Seismic Behavior of Long-Span Cable-Stayed Bridges
Special features of the earthquake-response analysis of cable-stayed bridges, subjected to multiple-support excitation, are presented including a basis for calculation of seismic forces...

Seismic Response Analysis of Two Major Bridge Structures
The seismic response analyses of two major bridge structures have been conducted. In these two bridges, portions of the piles are either submerged in the water or free-standing within...

Changes in Bridge Deck Flutter Derivatives Caused by Turbulence
This paper discusses some of the results of a wind tunnel study that tested the aeroelastic stability of section models in smooth and gusting flow. Wind gusts several times longer than...

Research Topics in Structural Identification
The authors examined a variety of possible research topics including identification and detection of nonlinearities, model improvement approaches, damage identification, power estimation...

A Discrete Model for the Estimation of the Elastic Abutment Stiffness
The purpose of this paper is the presentation of a simple method for the estimation of the abutment stiffness. In this method, the abutment is represented as a uniform rigid plate with...

Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...

Structural Dynamics in Hurricanes and Tornadoes
The random fluctuations of wind gusts produce dynamic interaction with structures. The objectives of this paper are to identify distinguishing differences in hurricane and tornado winds...

Engineering Laboratories' Role in Quality
Quality construction of a quality design is one goal which Owners, Design Professionals, and Contractors can all agree is needed if the project is to be truly successful. The Engineering...

Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....

Monitoring a Bridge's Pulse
The Sunshine Skyway Bridge, which collapsed in 1980, is being replaced by the Florida Department of Transportation. The new Sunshine Skyway Bridge, which spans Tampa Bay between Bradenton...

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...

Cold Regions Engineering
Engineers who plan, design, construct, operate and maintain facilities in cold regions must deal with all the concerns found in the more temperate areas of the world in addition to the...

Construction Approaches to the Navy's Floating Pier Concept
The subject of this paper is a floating pier which is currently under evaluation as a more cost-effective solution for berthing Navy ships. This new approach to pier design was sponsored...

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...

Efficiency Gains Using Micro Computers in Marina Design Engagements
This paper addresses improved efficiency in marina design engagements using low cost micro computers and low cost software. From the preparation of an offer for service, through design,...

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....

South Beach Harbor Project: Redevelopment of the San Francisco Waterfront
The redevelopment of a portion of San Francisco's Northern Waterfront is recounted, describing the planning and design process used to take an area of obsolete maritime facilities...

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...

Notes on Geotechnical Input to the Design of Graving Drydocks
These notes discuss geotechnical considerations in the design of graving drydocks, in particular the floors and walls of the structure. The effect of ground-water conditions in the design,...
