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, Robotics for Challenging Environments, contains the papers presented at the ASCE Specialty Conference on Robotics for Challenging...

Estimating Clay Liner and Cover Permeability Using Computational Neural Networks
The ability to provide a quick estimate of the permeability value to be expected in laboratory testing (of field samples) would help to predict potential problems in meeting the permeability...

A program for the Analysis of Pile Load Tests
The load capacity of piles are routinely determined from full scale pile load tests under actual field conditions. Several empirical methods were proposed for the analysis of field load/settlement...

Analysis of I-Girder Highway Bridges
Analysis of a bridge superstructure is complicated by the general geometric and loading conditions. Presented in this paper are three dimensional finite element modeling techniques used...

Graphic Visualization for Planning Heavy Lifts
The application of graphical visualization to construction can serve a wide variety of objectives and offers many significant benefits. Heavy lifts are an important component of industrial...

Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...

Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...

Seismic Analysis of Reinforced Concrete Building Using Finite-element Techniques
The response of a reinforced concrete building subjected to earthquake loading has been obtained on a personal computer using the finite-element code STARDYNE. For preliminary design,...

Seismic Evaluation of the Macy Street Bridge, Los Angeles, California, Using 3-D Nonlinear Pushover Methodologies
Nonlinearity of the overall bridge response has begun to be incorporated in the design process through a method known as nonlinear static pushover analysis, and this step is now being...

Nonlinear Analysis and Experimental Validation of a Stiffening Truss Chord of the Golden Gate Bridge
Finite element analyses of a stiffening truss chord of the Golden Gate Bridge were conducted by the authors as part of a comprehensive seismic retrofit project conducted by T. Y. Lin International...
