Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
Strength of Composite Beams under Seismic Loading
Effective width of a concrete slab of a composite beam is specified in various specifications, but their theoretical backgrounds are obscure. Originally, they must have been specified...
Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
Recent Research on Composite Structures for Building and Bridge Applications
Continuing research has been carried out at Lehigh University on composite structural members, joints, and overall systems. This paper summarizes the results of research on four selected...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
Recent Developments in Mixed Steel-Concrete Systems
Mixed steel-concrete systems have emerged into a well established new system that can be used as readily as either steel or concrete systems for high-rise buildings. Mixed systems offer...
Strength of Biaxially Loaded SRC Columns
The paper presents the results of an experimental study on the elasto-plastic behavior of 'Steel reinforced concrete (SRC)' columns subjected to biaxially eccentric...
Bond Check for Concrete-Filled Steel Tubular Columns
In order that a concrete-filled steel tubular column may display a maximum bearing capacity for sustaining the long-term vertical loads transferred from the steel beams to the steel tube...
Beam-to-Column Connection of a Composite Structure
Composite structures can exhibit excellent performance against seismic force, and fire safety as well. However, the traditional steel reinforced concrete (SRC) system or concrete encased...
Beam to Column Stress Transfer in Composite Structures
To clarify the mechanism of the stress transfer from the steel beam to the composite column through the beam-column joint, eight exterior beam column assemblies were tested under reversed...
Shear Strengths of Concrete-Filled Steel Box Elements
This study evaluated the ultimate strengths as well as the effect of the ultimate composite actions of concrete-filled steel composites under combined bending, shear, and axial forces....
Composite Columns?Design and Examples for Construction
The new German standard DIN 18806, part 1 gives the rules for the design of composite columns. The general method, taking into account all the inhomogeneties of the two materials steel...
Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...
Binding and Bonding Concrete to Composite Columns
Composite interaction between concrete encasement and structural steel shapes is limited unless lateral ties and/or mechanical attachments insure such interaction until desired strength...
Alignment Special Structures for Vancouver's ALRT
This paper describes the special long-span structures, offset columns, and bent structures used in situations where the standardized guideway components used in over 90 percent of the...
Utilization of Experimentally Obtained Connection Data in Assessing the Performance of Steel Frames
Data from over 70 separate experimental studies on steel beam to column connections are reviewed with particular reference to the joint's in-plane moment-rotation characteristic. More...
Prestress and Cracking Problems in Concrete Structural Components of an Elevated Rail Transit Guideway System
In 1983 the Department of Transportation evaluated the quality of construction of selected structural components on the Dade County Transportation Administration METRORAIL elevated guideways....
Rational Design of Beam-Columns in Steel
The paper discusses the procedure as currently recommended in the AISC Manual for selection of beam-columns in steel and points to the inadequacy of this procedure for quick convergence...
Unsymmetrically Reinforced Concrete Columns
The development of column strength formulas for unsymmetrically reinforced sections has been developed in previous papers. However, aids such as interaction diagrams have not been available...
