# Connections of Concrete Filled Steel Beams

*The concrete between the steel flanges of composite beams leads to problems in the connection area. To solve these problems four new types of beam-girder and beam-column connections are...*

Thin Walled Circular Concrete Filled Steel Tubular Columns

*The thin walled steel tube filled with high strength concrete delivers the economies of a concrete column with the speed of construction and the constructability of a steel column resulting...*

Proposal on Story Drift Limit Based on Axial Behavior of Column under Seismic Loads

*The main function of columns primarily is to support axial loads both under and after repeated lateral loading from earthquakes. A definition of the story drift limit in any structural...*

Behavior of Concrete-Filled Steel Tubular Three-Dimensional Subassemblages

*Three-dimensional subassemblages consisting of a concrete-filled steel tubular column and four H-shaped beams were tested under a constant axial load on the column, constant beam loads...*

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...*

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...*
