Case Studies of Bridge Scour in Western New York
As part of the New York State Thruway Authority's bridge hydrologic/hydraulic evaluation program, 63 structures over 42 stream crossings in western New York were assessed for scour potential...
Storm Drainage Channel Rehabilitation
30 km (19 miles) of existing concrete lines storm drainage channels were studied due to repeated failures. Alternate failures causes were hypothesized and evaluated. Physical testing was...
Determination of Hydraulic Roughness for Concrete-Lined, Supercritical Channels
A channel verification program has been initiated by the US Army Engineer District, Los Angeles to determine the hydraulic roughness of flow in a concrete channel. Specifically, this study...
Cable-tied Concrete Block Erosion Protection
An articulated concrete erosion protection system is investigated as a possible revetment for bridge piers to be used in place of the traditional rip-rap revetment. The system consists...
A New Type of Concrete Trapezoid Dam
A new type of 128.0 m height concrete trapezoid dam (t-d) has been built for the Wunana Town Hydroelectric Power Station (WTHPS). The paper presents its optimum section design, several...
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...
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...
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...
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...
The Connecting Method of Steel and Concrete Using Long Deformed Bar Studs
A new welding technique for long horizontal studs of 19 mm and 22 mm diameters was established. The transmission of shearing and bending forces was evaluated using large model tests. Actual...
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...
Summary Report Design Session
The Tuesday presentations were devoted to design. Eight papers were presented in the morning general session and 17 presentations were made in 4 concurrent evening workshops. Diversity...
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...
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...
Double Skin Composite Construction for Submerged Tube Tunnels
A new form of sandwich construction consisting of two relatively thin steel plates, with a concrete infill has been developed for use in the construction of submerged tube tunnels. The...
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...
Semi-Rigid Joint Action in Composite Frames: Numerical Analysis and Design Criteria
The paper focusses on the analysis of semi-rigid composite frames, reporting mainly on the results of a research study which combines the experimental and theoretical approaches. Attention...
Seismic Response of Composite Coupled Walls
In many structures, height restrictions may require coupling of reinforced concrete walls by structural steel beams rather than conventional reinforced concrete beams. Through an experimental...
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...
Composite Columns Subjected to Bending and Shear
This paper describes experimental as well as analytical studies of the post elastic deformation and fracture behaviors of wide flange steel encased reinforced concrete (SRC) composite...
