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...
Microtunneling: Overview and Case Study
Microtunneling is defined in the United States as a remotely controlled, laser guided pipe jacking process, which does not require personnel entry. This paper describes the components...
The Pipe/Soil Stiffness Ratio Variable
This paper reviews the factors which affect the reactions and defines performance limitations of buried flexible plastic pipe as a function of load-induced strains and deflections. The...
Ovality in Pipe Rehabilitation Design
Pipes in need of structural rehabilitation often have longitudinal cracks (at the crown and elsewhere) and exhibit significant ovality (5-10%). When these pipes are lined with current...
Sliplining: Design and Installation Considerations for Polyethylene Pipe
The design methodology and installation procedure for polyethylene slipline renewal are discussed. When designing there are two critical phases which must be considered: (1) short-term...
Trenchless Diversity Fuels Growth of Construction Activities
This paper describes a variety of trenchless technology methods of reconstructing America's decaying pipeline infrastructure by using minimum and /or 'no-dig processes'. The decay of our...
Microtunneling with PVC Pipe
PVC is a suitable and economical product for sewer system construction. However, in the past, utilization of PVC sewer pipe in microtunneling was impossible due to axial thrust load limitations...
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...
Pipeline Leak Detection Based on Mass Balance
Current technologies in Supervisory Control and Data Acquisition (SCADA) systems enable pipeline leak detection to be carried out in real time by software-based methods. This paper discusses...
