Hundreds of Bridges�Thousands of Cracks
In the past 10 years hundreds of welded steel bridges, most of them relatively new, have suffered thousands of cracks due to secondary stresses, that is, the cracks are caused by deflections...

On the Design of Continuous Composite Beams
Methods of analysis and design of continuous composite beams are presented. Numerical analysis is used to determine the effective width of the slabs to be used in design. The influence...

Behavior and Strength of Stub-Girder Floor Systems
The paper presents a detailed evaluation of the behavior and strength characteristics of the stub-girder floor system. This is a composite girder and beam structure that integrates the...

Proposed Design Criteria for Composite Steel Deck Slabs
Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite...

Design and Testing of a 400 Ft Span Plate Girder Bridge
The paper describes design features and testing of the Madawaska River Bridge. The bridge is unique in being the longest span plate girder bridge in Ontario, having continuous spans of...

The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...

Experimental Investigation of Composite Rigid Frames
According to the series of tests conducted by the authors on composite rigid frame models, the compressive principal stress in the steel web plate at the corner panel was considerably...

A History of Adhesive Bonded Composite Members
The history and development of adhesive bonding in composite members is traced. Two forms of composite members are explained. Research from different parts of the world is compared. Applications...

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...

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...

Bond Stress of Embedded Steel Shapes in Concrete
This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous...

Recent Developments for Composite Buildings in Japan
Research work and construction practice of composite steel and reinforced concrete structural systems in Japan are reviewed, based on the data gathered by the working group of the Architectural...

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...

Design of Framed Steel Structures with Infill Reinforced Concrete Walls
It is a well-known fact that an infill shear wall in a frame acts as a compressive diagonal strut, giving strength and inflexibility to the frame. Recently the Architectural Institute...

Seismic Capacity Evaluation of SRC Buildings
