Stabilizing Winglet Pair for Slender Bridge Decks
This paper describes the effectiveness, as an aerodynamic damper, of a pair of winglets mounted parallel to, and clear from, bridge decks that might otherwise be aeroelastically unstable....

Wind Tunnel Investigation of a Twin Deck Suspension Bridge
Wind tunnel measurements of the response of a twin deck suspension bridge to dynamic wind loads are presented. The investigation was concerned with the determination of the deck response...

Comparative WWind Tunnel Testing of Bridge Road Decks
A 1:75 scale full aeroelastic model of the Quincy Bridge over the Mississippi River was tested in the National Research Council of Canada 9 m multiplied by 9 m wind tunnel. Tests were...

Utility Programs for DWOPER and DAMBRK
Time and computer resources greatly limit potential investigations and sensitivity anslyses. In order to facilitate modeling with the National Weather Service (NWS) programs DWOPER (Operational...

Aluminum Orthotropic Bridge Deck Verification
This paper reports tests conducted to evaluate an aluminum orthotropic deck. Approximately 60 welded T-joints with 6061-T6 stems and 5456-H321 plate were subjected to flexural fatigue...

Intelligent User Interface for Network Signal Optimization Programs
This paper presents the design philosophy and program intelligence used in EZ-TRANSYT and EZ-SIGOP, powerful multi-window input data managers for TRANSYT-7F and SIGOP-III, respectively....

Applications of Automated Interpretation to Sensor Data
This paper focuses on potential applications of the AISD. (A knowledge-based concept for automating the interpretation of sensor data) concept in civil engineering. A number of potential...

Some Aspects of Bridge Instrumentation
This paper provides some guidelines about the proper arrangement of strong motion instruments for the proper assessment of some particular phenomena that have been either observed in past...

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...

The Parking Problem
Corrosion of parking garage decks has become a multi-billion dollar problem, caused primarily by deicing salts that seep into the concrete and attack reinforcing steel. Design and construction...

U.S. Navy's First Double Deck Pier
The present single level concept of pier construction limits the pier-side service to the fleet. With the ever increasing requirements for utilities to the ships, and maintenance and training...

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...

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...

Berthing Impact Force Distribution on Pile Supported Pier Structures
This paper investigates the degree to which a berthing impact force is distributed to the pile bents of batter pile supported pier structures. A procedure is developed to estimate the...

Capacity Rating of Existing Piers and Wharves
This paper outlines a method for physically surveying the present material condition of existing piers and wharves and assigning to them a safe rated capacity expressed in displacement...

Rehabbing under Traffic
Redecking the Golden Gate Bridge with a light weight orthotropic steel plate deck left the 49 year old monument 11,000 tons lighter, 2 feet wider, and ready to carry traffic for the next...

Restoration of Navy LTA (Lighter Than Air) Hangars
In 1942 and 1943 the Government constructed a series of 16 blimp hangars at ten Naval Air Stations along the east coast, west coast and gulf coast. The hangars erected in pairs housed...

Timber in Bridges of West Coast
Experience has shown that timber can function very well as a bridge material. Proper inspection procedures combined with a structured maintenance program can improve the performance of...
