Subsidence Properties of Holocene Sediments: S. La.
As part of a comprehensive USGS-sponsored study of processes that drive subsidence and wetland loss in south Louisiana, two continuously cored deep borings (60 m and 72 m) were acquired...
Dredged Material Filled Geotextile Containers
Design and construction of geotextile containers hydraulically and mechanically filled with a variety of dredged material types has gained popularity in the past few years because of their...
Calculation of Longshore Sediment Transport on Abrasive Coasts with Attached Pebble Beaches
The calculation scheme and expressions are suggested for flow power of universal nature which expresses the flow capacity such that the sediment transport is proportional to the flow longitudinal...
Rheometry of Natural Sediment Slurries
Recent experimental analyses of natural sediment slurries yield diverse results yet exhibit broad commonality of rheological responses under a range of conditions and shear rates. Results...
New Canadian Provisions Related to the Design of Composite Beams
In this paper, the new provisions in CAN/CSA-S16.1-M89 for the design of composite beams, together with reasons for changes, are discussed. Some of the new provisions reflect results of...
Shear Connection in Composite Beams
This paper considers the influence of the shape of the deck profile on the shear connection of composite beams. It was found that the existing strength reduction factor can be unconservative...
Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...
Modern Design Concept for Composite Slabs with Ductile Behaviour
Numerous tests with different types of composite slabs have been carried out in the laboratory for constructional engineering of the University of Kaiserslautern, Germany in order to determine...
Design of Shear Connectors in Composite Bridge Beams
A new approach is described for the design of stud shear connectors, in composite steel and concrete beams that are subjected to vehicular loads, which allows for the interaction between...
Design of Composite Slabs for Vertical Shear
Three major modes of failure should be considered in the design of the positive moment regions of composite slabs incorporating profiled steel sheeting, viz.: flexure, longitudinal slip...
Investigation of Corners and Joints Applied to a Steel-Concrete Composite Caisson
We have developed a caisson composed of steel-concrete composite slabs and steel structures, which we call a `Hybrid Caisson.' We studied the structural principles and usability of the...
Development of Composite Slab with Truss-Typed Shear Connectors
This paper describes the results of the test on a steel-concrete composite slab with truss-typed shear connectors. This composite slab was recently developed. A series of tests were conducted...
Connection of Beam Flange to Concrete-Filled Tubular Column
Research has been carried out on a frame composed of a concrete-filled steel tubular column and H-shaped steel beam with the aim of developing a reasonable connection method. The proposed...
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...
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,...
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...
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...
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...
