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...

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...

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...

Large Displacement Analysis for Structural Stability Problems
In this paper, two widely different methods of large displacement analyses are considered. The first is a discrete element analysis which is particularly effective for line structures...

R/C Columns Under Axial and Bi-Directional Lateral Loads
The reliability of a model, called a multi-spring model, was examined to simulate the observed response of reinforced concrete columns subjected to varying high axial loads and bi-directional...

Buckling Loads of Columns Made of Viscoelastic Materials
This is about the developing of relationships for predicting the change of buckling loads of columns made of viscoelastic materials under different loads. When a columnlike structural...
