Slide Stabilization with Stone-Fill Trenches

Reliability Model for Bridge Columns under Seismic Loads
This paper develops a model for the analysis of the reliability of bridge columns under earthquake loads. Probability of failure is defined as the probability that the displacement ductility...

Critical Buckling Load Statistics of an Uncertain Column
The objective of this paper is to examine the statistics of the buckling load of a column with uncertain material properties. The elastic modulus is assumed to be a random process that...

A Monumental Task
The geotechnical consultants, structural engineer and contractor combined to overcome difficult soils, underground subway structures and buried utilities when building the foundations...

Summary of Noncohesive Sediment Transport Processes at the Bed/Water Column Interface

NCASI Experiments Related to Validation of Sediment-Water Column Exchange Models for Hydrophobic Chemicals

Flux of Metals Between Sediment and the Water Column

A Preliminary Evaluation of Transport Mechanisms for Multiple Substrates in a Laboratory Column System

Atrazine Biodegradation in Biological GAC Columns

Full Scale Tests on Concentrically Loaded Fiber-Reinforced Pultruded Columns
This paper briefly reports on the experimental investigation in connection with the short term behavior of pultruded structural members under concentric loading. In particular, results...

Investigation of the Behavior of Reinforced Plastic Columns with Concrete Core
This paper describes an experimental investigation into the behavior of reinforced plastic columns with tubular (hollow) sections. The columns were pultruded and had a cross-section which...

Behavior of Externally Confined Concrete Columns
This paper investigates the feasibility of strengthening of seismically deficient concrete columns with high-strength fiber composite straps. The concrete columns will be externally confined...

Fiber/Epoxy Composites Strengthen Bridge Columns
The California Department of Transportation is using high strength fiber/epoxy composites to strengthen existing reinforced concrete bridge columns. These advanced composite materials...

Flexible Membrane Wave Barrier
A linear analytical model is developed for the dynamic response of a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column...

Fiber-Reinforced Plastic Composite Columns

Preliminary Results of Direct Tension Tests on First-Year Sea Ice Samples
We present the initial results of our tests to determine the tensile behavior of columnar sea ice over a range of temperatures extending from -20 to -3°C and strain rates of 10-5...

Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...

Column Buckling Mode Classification Using a Back Propagation Neural Network
A back propagation neural network (Rumelhart, Hinton and Williams, 1986) is used to analyze and classify the buckling mode shapes of structural columns. The input patterns consist of vectors...

An Efficient Parallel-Vector Equation Solver
An efficient parallel-vector equation solver is developed for supercomputers. The matrix is stored in a combined column and row orientation style which improves the vector performance...

Developments in the Use of Cubic B-Splines in the Compound Strip Method
A general cubic B-spline compound strip method (BCSM) has been developed to analyze thin plates, stiffened plates, folded plates, and box-girders. In the BCSM a problem is first partially...
