Mixing Character and Meandering Mechanism of a Plane Jet Bounded in a Shallow Water Layer
A plane jet in a shallow water layer is characterized by the jet width b1/2 much larger than the water depth h at large downstream distances x/h...
Structure of Coastal Upwelling on a Sloping Bottom
A large eddy simulation of coastal upwelling on a sloping bottom is carried out. The structure of the upwelling consists of a persistent primary front, a temporary secondary front which...
River Engineering Flows and Some Related Structures (State of the Art)
The first part of the paper deals with a simplified overall review of water flows. Laminar versus turbulent, visualization of flow with unsteady 3-D manner and some typical hydraulic structures...
Bridge Scour Evaluations in Washington State
Eighteen existing bridges were investigated for Washington State DOT as part of the FHWA National Scour Evaluation Program. Investigations included review of file information, site inspection,...
Simulation of 3D Free Surface Flows in Hydraulic Structure with Submerged Flow Passages
This paper presents primarily the results of an application of the newly refined computational simulation model to study three-dimensional flows in a lock and dam system, which has submerged...
Modeling the Tides of Massachusetts and Cape Cod Bays
A time-dependent, three-dimensional numerical modeling study of the tides of Massachusetts and Cape Code Bays, motivated by construction of a new sewage treatment plant and ocean outfall...
Flow Diversion in a Steep, Coarse-Bed Stream
A case study is presented of the hydraulic design of a diversion structure in a high velocity, coarse bed streamcourse. Mill Creek, a tributary to the Upper Jordan River in the southern...
Composite Construction?Recent Past, Present and Near Future
The present paper covers a shorter time span. It is divided into three parts: recent past, present and near future. The remarks regarding the recent past are limited to my personal experiences....
New Developments in Eurocode 4
The European Community has initiated the preparation of a set of harmonized structural codes. Eurocode 4 is the code for the design of composite steel and concrete structures. The first...
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...
Composite Beams: Redistribution, Reliability, and Lateral Buckling
Research relevant to three aspects of the design of composite beams for ultimate limit states is summarized. These are: the redistribution in continuous beams and in framed structures...
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...
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...
Highlights of the New ASCE Standards on Composite Deck Floor Slabs
This paper presents highlights of the newly approved and printed ASCE Standard on the design and construction of composite floor deck slabs utilizing cold-formed steel. In 1992 four documents...
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...
Chinese Standard for Concrete-Filled Tube Columns
In this paper an outline is given of the background, the design approach and some principal features of the Chinese Specification for the Design and Construction of Concrete-filled Steel...
European Good Practice in Composite Floor Construction
Previous European experience, research and design for composite slabs with profiled steel decking are discussed. Present efforts to harmonize composite slab design and good construction...
Composite Space Frame?Experimental/Analytical Study
This paper describes work carried out on a composite space frame system. The system, previously developed for roof construction, comprised a pyramidal arrangement of steel angles and circular...
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....
