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...

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...

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...

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...

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...

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...

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...

Steel Panel Encased R.C. Composite Shear Walls
In order to make clear the fundamental resisting mechanisms of composite shear walls, tests are carried out on the composite unit rigid frames with various infilled shear walls. Composite...

The Behaviour of Reinforced Concrete Beams Manufactured with Side Profile Sheets
The paper describes in qualitative terms the fundamental principles that control the behaviour of a completely new form of construction in which reinforced concrete beams are constructed...

Townsite Lateral-Stage 2 Belle Fourche Unit - Cheyenne Division Concrete: Pipe with Dumped Bedding and Embedment
In 1933, M. G. Spangler presented three bedding configurations and the concept of a bedding factor to relate the supporting strength of buried concrete pipe to the strength obtained in...

Flow Study of In-Service Sanitary Sewers Rehabilitated with Insitupipe
In an effort to define the flow characteristics of sanitary sewer segments rehabilitated with Insituform under normal in-service conditions, Insituform of North America, Inc. (currently...

PCCP Inspection and Remediation Methods
This paper presents detailed investigative procedures and methodology used to locate corroded Prestressed Concrete Cylinder Pipes (PCCP). It examines data collection by electronic devices,...

Joint Outfall H Relief Trunk Sewer System
The Joint Outfall 'H' Relief Trunk Sewer System consists of the construction of 11.3 kilometers (7 miles) of polyvinyl chloride lined reinforced concrete pipe varying in diameter from...

Concrete Pipe for Sanitary Sewers Corrosion Protection Update
Significant advances have been made in the last decade in the area of sanitary sewer design techniques. Some of the most important advances have been in the prediction and prevention of...

Caustic Spray for Sewer Crown Corrosion Control
A novel method to control sewer crown corrosion which involves spray application of a caustic solution to the sewer crown is described. Corrosion control using this concept is based on...
