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)...
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,...
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...
Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...
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...
Effects of Connections on Composite Frames
This paper summarizes the preliminary findings from an experimental and theoretical study of the influence of composite connections on frame behaviour. The first part of the work included...
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...
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...
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...
Structural Design on Ductile Iron Pipe
The thickness class designation for Ductile Iron pipe has been changed to a pressure class designation in the 1991 revision of the C150/A21.50 ANSI standard. However, the same conservative...
Installing a Raw Water Line by Microtunneling
Construction began in 1991 on a new water treatment plan for the Towns of Cary and Apex, with B. Everett Jordan Lake as a water source. Installation of two 1,400 mm raw water lines approximately...
An Evaluation of Fiberglass Pipe Made by Three Different Manufacturing Processes for use in Water Transmission Projects
Fiberglass pipe is made primarily using continuous filament wound process, discontinuous helical filament wound process, and centrifugal cast process. Some 40 countries around the world...
The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
Microtunneling of Vitrified Clay Pipe in the United States
Vitrified clay pipe (VCP) has been used for centuries to convey waste water away for cities. In Europe and Japan, VCP has been used in the microtunnelling process for longer than 10 years....
Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...
Potential of Vegetable Oil as a Transportation Fuel
The esters of vegetable oils (Biodiesel) have potential as direct replacements for diesel fuel in compression ignition engines. This paper discusses fuel properties, short and long term...
