Seismic Performance and Retrofit of the Golden Gate Bridge
Since its opening in 1937, the Golden Gate Bridge has endured and functions as an important transportation link for Bay Area commerce and commuters. After an earthquake in 1989, T.Y. Lin...
Innovations in Major Suspension Bridge Design
Before the Tacoma disaster, the trend in bridge-building is on increasing slenderness. But since its occurrence, a high degree of aerodynamic stability is required. Presented are designs...
Akashi-Kaikyo Bridge Underconstruction
This paper presents 1) brief history of the survey work, 2) brief description of the physical dimensions and structural system, 3) major studies for the design, 4) development of higher...
Lateral Response of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This project addresses the out-of-plane response to lateral loading...
Optimization for Earthquake Loads
Structural optimization for seismic loads can be approached from a deterministic or nondeterministic point of view. Deterministically, the major difference between optimization of statically...
Flange Local Buckling and Behavior of I-Sections
A simple kinematic model is proposed to determine the locally buckled shape of the compressive flange plate of I-sections subjected to pure bending or bending combined with axial thrust....
Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...
A Field and Modeling Study of Residual Circulation in Sarasota Bay and Tampa Bay, Florida
Based on analysis of current data at three distinct locations within the Sarasota/Tampa Bay system, we defined the residual circulation patterns and the relative influences by tides, wind...
Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...
Evaluation of Depth-Limited Wave Breaking Criteria
Numerous criteria exists for predicting incipient wave breaking. These criteria were verified with a limited number of data sets or under limited number of data sets or under limited beach...
Design of an In-Situ Directional Wave Gage for One Year Deployments
This paper describes the design and implementation of a new in-situ, directional wave gage that records hourly directional spectra continuously during a 13-month deployment period. If...
Design and Testing of the NDBC Wave Processing Module
The U.S National Data Buoy Center (NDBC) has developed a new wave data acquisition and processing system, called the Wave Processing Module (WPM), using state-of-the-art technologies and...
Buoy Directional Wave Measurements Using Magnetic Field Components
Directional wave data can be estimated using the heave, pitch and roll motion of a discus buoy, which are conventionally measured by a pitch-roll sensor. To reduce the size and cost, this...
Evaluation of a Third-Generation Wave Model for the U.S. Atlantic Coast
Accurate description of surface wind fields in ocean spectral wave modelling is of critical importance to estimating storm - induced wave conditions along a coastal reach. A new approach...
Wave Monitoring in The Southern California Bight
An overview of recent research by the Coastal Information Program (CDIP), aimed at effectively monitoring wave conditions in the Southern California Bight, is presented. The topographic...
Experimental Study of Monochromatic Wave-Ebb Current Interaction
Laboratory experiments were conducted in a 26-m by 36-m basin with a 1:30 plan beach to study the interaction of monochromatic waves and an ebb current in and near shallow entrance channel....
Wave Runup on and Wave Reflection from Coastal Structures
Wave runup and wave reflection are two of the most important, easily quantifiable variables that influence the design of coastal structures. Unfortunately there are very few comprehensive...
Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater ? Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...
Robotics for Challenging Environments
This volume,
Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
