Steel Beams with Reinforced Concrete Stiffened Ends
For the construction of office building with long span beams, steel beams with reinforced concrete stiffened ends are being used in order to increase the stiffness. This paper describes...
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...
Recent Developments in Composite Bridges
Composite steel and concrete bridges are becoming increasingly popular, in particular for short and medium spans. This renewed interest is due first of all to the great freedom for creativity...
Concrete Arch Bridges Using Composite Techniques
Use of composite structure is an advantageous method to construct concrete arch bridges. This paper reports two successful examples of concrete arch bridges of composite construction using...
Longspan Bridges with Double Composite Action
Continuous steel composite bridges with double composite action have, besides the concrete roadway slab, a concrete bottom chord at the haunches over the main piers. This concrete bottom...
Replacement Steel Bridges for Motorway Widening
Case studies are presented of new applications of composite construction which offer speedy construction of replacement bridges over existing motorways. Spans of 45 m clear the widened...
Hybrid Lifted Structure for the Collserola Tower
The structure of the 300 m. Collserola Tower is a hybrid system formed by three combined structural systems consisting of: - a very slender cylindrical concrete shaft: - a large steel...
Strength and Stiffness Behavior of Composite Steel Grid Decks
This paper briefly discusses the historical development of composite steel grid decks. The static and fatigue behavior under bending of filled and unfilled steel grid decks (exodermic)...
Fatigue of a Steel Plate and Concrete Composite Bridge Deck by Moving Loads
This paper is devoted to reveal fatigue characteristics of a steel plate and concrete composite bridge deck, which is often called the Robinson slabs, subjected to vehicle loads. 16 model...
Recent Developments in Composite Bridge Building in Germany
In the 1980s a movement started to build composite bridges with reinforced concrete slabs and to renounce to prestress them in one or both directions. This type of bridge is advantageous...
Application and Recent Development of a Numerical Model for Composite Beams with Partial Shear Connection
This paper deals with numeric analysis of composite steel and concrete beams for loads up to the ultimate beam capacity. Two versions of a numerical model are presented addressing such...
Influence on Steel Deck on Composite Beam Strength
Results of a recent study were described in which 7 push-out tests and 4 composite beam tests were conducted. The results were consistent with other recent studies reported in the literature,...
Composite Beams with Headed Studs in Narrow Ribbed Metal Deck
This paper presents the results of sixteen push-out tests conducted to study the behavior of headed stud connectors in composite beams with narrow ribbed metal deck placed parallel to...
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...
Numerical Analysis of Composite Slab Behavior
A new calculation procedure is described which provides an alternative to full-scale testing for composite slabs with ribbed decking used in buildings. This procedure consists of combining...
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...
Behavior of Unbonded Braces Restrained by Reinforced Concrete and FRP
A new composite steel brace called an unbonded brace (UB) is proposed to enhance the capacity of a steel brace to carry a compressive load of almost up to the yield strength of the steel...
Perfobond Rib Connectors for Composite Beams
In this paper, the influence of concrete strength, transverse reinforcement and concrete dowels on the capacity of perfobond rib shear connectors is examined. Perfobond rib connector is...
