Joint Design in Composite Columns/Steel Beam Structures
The use of a composite building system, utilizing a composite exterior column and a concrete spandrel beam system, proposed by Dr. Fazlur Khan in 1967, is recalled. In the last 25 years,...

Axial Capacity of Concrete Infilled Steel Box Column with Biaxial Bending
The objective of this study was to investigate the feasibility of using the Bresler reciprocal load method to calculate the axial capacity of a concrete infilled steel box column subjected...

Buckling of Guyed Towers
The buckling load of a column guyed in a plane by symmetric guy wires is considered. The column is built-in at the ground, supported at the top by guy wires, and is loaded by a vertical...

An Innovative Connection Detail for High-Rise Buildings
Composite columns consisting of hollow steel tubes filled with high strength concrete have been used in high rise building construction in the USA and Far East Asian countries. The focus...

Seismic Design of Steel Beam-to-Box Column Connections
This paper is a study of the ductility requirements of steel beam-to-box column connections using the bolted beam web and welded beam flange details. Since the beam moment at the connection...

The Use of Built-Up Compression Members—A Fabricator's Viewpoint
A variety of cross-sections of built-up compression members that have been used are shown. Suggested items that need to be addressed for the successful design and fabrication are discussed....

A New Theory of Built-Up Columns
In laced, battened and other built up columns the shear stiffness of the web can have a significant effect on the overall buckling load. At the present time, such columns are analyzed...

QST Rolled Shapes, a New Generation of HSLA Compression Members
With the development of the Quenching and Self-Tempering (QST) process by the Luxembourg steelmaker ARBED S.A., a new generation of High Strength Low Alloy (HSLA) rolled shapes has become...

Creep and Shrinkage of Composite Columns in Tall Buildings
The simultaneous presence of steel and composite columns in tall buildings is a common occurrence. The axial shortening characteristics of composite columns are influenced by creep and...

How to Optimize Reinforced Concrete Systems
A straightforward procedure for the optimization of member dimensions and reinforcement design in concrete structures consisting of beams, slabs, and columns is presented. The procedure...

Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...

Modeling Adsorption of Mixtures of Radionuclides by Zeolitized Tuff
Multi-solute sorption isotherms were measured using 'nonscents', a zeolitized volcanic tuff material from Southeast Arizona. Isotherms for the three constituent binaries, Sr-Co, Cs-Sr...

Neptunium Retardation with Tuffs and Groundwaters from Yucca Mountain
The retardation of neptunium was studied using batch sorption and column techniques. Pure mineral separates, tuffs and groundwaters from Yucca Mountain were used for these experiments....

Toll Plaza to Stand on Buried Columns

After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...

Chinese Standard for Concrete-Filled Tube Columns
In this paper an outline is given of the background, the design approach and some principal features of the Chinese Specification for the Design and Construction of Concrete-filled Steel...

Comparison of Simple Calculation Methods for the Fire Design of Composite Columns and Beams
There is a need for approximate calculation methods to do the fire design of composite structures. Several of such methods for composite beams and columns have been compared to find out...

Summary Report Design Session
The Tuesday presentations were devoted to design. Eight papers were presented in the morning general session and 17 presentations were made in 4 concurrent evening workshops. Diversity...

Interaction of Steel Structure and Composite Supercolumns in Spine Structures
Modern architecture has departed from uniform rectangular cigarette boxes for high-rise buildings. A structural system which goes uninterrupted through the common denominator of the varying...

Composite Columns Subjected to Bending and Shear
This paper describes experimental as well as analytical studies of the post elastic deformation and fracture behaviors of wide flange steel encased reinforced concrete (SRC) composite...
