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...
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...
Columns of Concrete-Filled Rectangular Hollow Sections
Concrete-filled hollow sections are normally used as columns in multi-storey buildings and also in similar structures. Such columns may be filled with plain concrete with no need for any...
Connection of Beam Flange to Concrete-Filled Tubular Column
Research has been carried out on a frame composed of a concrete-filled steel tubular column and H-shaped steel beam with the aim of developing a reasonable connection method. The proposed...
Full-scale Tests on Composite Connections
Tests have been carried out on eight full-scale composite connections in which the columns were manufactured of concrete-filled steel circular hollow sections (CHS). The connections were...
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...
Composite Walling
This paper describes a study into a system of walling that comprises two skins of profiled steel sheeting infilled with concrete. During construction the steel sheeting acts as permanent...
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...
Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...
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...
