Local Scour Measurements at Bridge Piers in Alberta
A summary of local pier scour data collected by Alberta Transportation and Utilities (AT & U) over the past 30 years is presented. Several methods used to gather this data are...
A New In-Stream Aerator
Experiments on microporous, polymeric, hollow fiber membranes are being conducted for application to in-stream aeration. The hollow fibers are scaled on one end and connected to an oxygen...
Sediment and Water Quality Control Devices in Small Watersheds
The physical behavior and health of an alluvial stream depends on the extent of man's interferences in its tributary areas. In its natural setting a stream provides three main functions...
Two Full-Scale Tests of Class 3 Composite Beams
This paper presents two tests of continuous composite beams comprising two 7.5 m spans and two concentrated loads close to the intermediate support. Although the cross-sections on the...
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...
Slim-Floor Beams: Design Criteria and Structural Behaviour
Partially concrete-encased steel beams are mostly employed due to their natural resistance to fire, but there may also be other reasons, e.g. to obtain smaller depths of construction....
Comparison of Simple Calculation Methods for the Fire Design of Composite Columns and Beams
There is a need for approximate calculation methods to do the fire design of composite structures. Several of such methods for composite beams and columns have been compared to find out...
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...
Interaction of Steel Structure and Composite Supercolumns in Spine Structures
Modern architecture has departed from uniform rectangular cigarette boxes for high-rise buildings. A structural system which goes uninterrupted through the common denominator of the varying...
Cyclic Lateral Load Analysis of Composite Frames
A method of analysis for composite building frames subjected to repeated and reversed lateral loads has been developed as part of an overall investigation of seismic response of composite...
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...
A New Method from China to Determine Load-Carrying Capacity for CFST Members
The most common research method for CFST (concrete-filled steel tubular) members is to study the behaviors of the steel tube and the core concrete separately, then add them together to...
Full-scale Tests on Composite Connections
Tests have been carried out on eight full-scale composite connections in which the columns were manufactured of concrete-filled steel circular hollow sections (CHS). The connections were...
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...
Proposal on Story Drift Limit Based on Axial Behavior of Column under Seismic Loads
The main function of columns primarily is to support axial loads both under and after repeated lateral loading from earthquakes. A definition of the story drift limit in any structural...
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...
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...
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...
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...
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...
