The Definition of a Short Composite Column
A `short' column in composite construction is defined as one which can be designed for its cross-section strength alone without the need to consider stability effects. An extensive study...

Force Transfer in Composite Columns
The force transfer from steel to concrete without mechanical transfer devices in composite columns at points of load introduction is studied. A mechanism of force transfer and the factors...

New Steel Beam to Composite Column Connection Detail
Composite columns consisting of hollow steel tubes filled with high strength concrete with compressive strength exceeding 10000 psi (69 MPa) are being used in high-rise buildings. Connecting...

Removal, Replacement and Rehabilitation of Concrete Slabs
The project involved existing one-way slabs experiencing severe corrosion damage. The slabs were removed and replaced while salvaging the concrete beams and frame components. Significant...

Silica Fume Concrete: A Solution to Steel Reinforcement Corrosion in Concrete
This paper discusses the utilization of silica fume concrete admixture to prevent reinforcing steel corrosion. The mechanism of steel corrosion in salt impregnated concrete is described,...

Generic Problems
Generic Problems are basic problems in structural mechanics that recur frequently, have been investigated experimentally and involve the behavior of elements or components found in many...

Structural Fire Resistance Design of Wood Beams and Columns: A Comparison of European and North American Practices
North American and Eurocode design methods for fire-resistive exposed wood members provide a very good example of the translation of research into practical engineering design procedures....

Composite Construction in Steel and Concrete II
Composite steel-concrete structures are widely used throughout the world. Applications range from buildings to bridges to foundations to special structures. In many instances extensive...

Arches For A Parkway
The final phase of construction on the Natchez Trace Parkway (which follows a centuries-old 450 mi trail between Natchez, Miss. and Nashville, Tenn.) is nearing completion almost 60 years...

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...

Design of Floating Stone Columns in Hydraulic Fill

Resonant Column Testing of Dynamic Rock Properties
Critical parameters for geophysical wave propagation studies are the dynamic elastic properties (shear and Young's moduli, and Poisson's ratio) and the intrinsic material damping of rocks....

Investigation of Parametrically-Induced Excitation in Concrete Columns
A mathematical model is developed which accounts for the non-linear material characteristic of concrete members. The axial and transverse motions of concrete columns, are found to be second-order...

An Analysis of an Inflatable Module for Planetary Surfaces
Design and construction of a structure on planetary surfaces requires addressing a host of issues not encountered on Earth. A modular quilted inflatable structure consisting of thin membranes...

Modeling 3-D Circulation Using the DSS Technique
The direct stress solution (DSS) technique allows a numerical internal mode solution for the vertical variation of shear stress, rather than velocity, in a three-dimensional circulation...

Microbiologically Induced Corrosion
Researchers investigating a building whose columns bled a colorless liquid found that the building was under attack by microorganisms. A community of bacteria had contaminated the fireproofing...

Evaluation of Failure Potential in Mudstone Slopes Using Fuzzy Sets

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...
