Metal and Plastic Pipelines: Design and Construction Aspects
This paper discusses design and construction aspects of four cross-country pipelines that were built in central Alberta, Canada during 1982-1983. The first two pipelines, carrying different...
Successful Use of Trench Box in Sewer Line Construction
Faced with the problems of ever increasing construction costs, more and more methods are being employed in an attempt to keep expenses to a minimum without sacrificing the quality of construction...
Simplified Stress and Deformation Analysis for Pipeline Construction
This paper discusses the strength and deformation behavior of flexible steel pipes during pipeline construction. Some possible simple and quick solutions to these special design and construction...
Longitudinal Prestressed Piping for District Heating
The design of recently installed hot water district heating systems in the United States is based on similar systems developed in Europe. Longitudinal prestressing is used in the design...
Stress-Intensification Factor and Flexibility Factor in Seismic Analysis of Continuous Buried Pipelines
The topics of intensified stresses and increased flexibility in pipe bends subjected to bending loads are discussed in this paper. Also discussed are dynamic strain compatibility between...
Modeling Boundary Layer Flow in Stormwater Detention Basins
An iterative procedure involving an implicit finite difference numerical scheme was implemented on an IBM personal computer for solving steady, uniform and nonuniform boundary layer flow...
A New Alternative in Steel Construction?Partially Restrained Connections
Lack of formal training in methods as well as the lack of specific guidelines have limited the understanding and utilization of semi-rigid connection technology. A renewed interest in...
The Effect of Connection Flexibility on Steel Members and Frame Stability
With the advent of Load and Resistance Factor Design (LRFD) and the many existing moment-rotation curves for connections, the use of actual connection flexibility in the design process...
Utilization of Experimentally Obtained Connection Data in Assessing the Performance of Steel Frames
Data from over 70 separate experimental studies on steel beam to column connections are reviewed with particular reference to the joint's in-plane moment-rotation characteristic. More...
Buckling of Flexibly-Joined Simple Frames
A nonlinear analysis of plane elastic frames is presented. The static loading consists of both eccentric concentrated loads (near the joints) and uniformly distributed loads on all or...
Behaviour and Strength of Steel Frames with Semi-Rigid Connections
A research study was started at the Politecnico of Milan (Italy) to investigate the influence of the main governing parameters on the behaviour and strength of flexible frames. A sophisticated...
Joint Flexibility in Steel Frames
This paper investigates the effects of connection flexibility and panel zone deformation on the behavior of plane steel frames. The incorporation of these factors in frame analysis will...
Flexibility of Steel Seismic Moment Connections
Relevant Berkeley experimental results are critically evaluated to determine the flexibility of W18 W24 beam joints with and without stiffeners and/or doubler plates. The paper discusses...
Research Needs for Extant Iron and Steel Buildings
A brief review of iron- and steel-making processes is background for the development of shapes and codes. Sources of information for the condition assessment of iron and steel buildings...
Structural Integrity Assessment of the Flexible 870 Advanced Design Bus
The Grumman Flxible 870, a lightweight advanced design urban bus, entered service in Atlanta, GA in 1978, and some 2,800 of these buses were in service nationwide by 1980. In the autumn...
Restoring the Capitol's West Front
After 25 years of debate, preservation (rather than extension) of the West Front of the U.S. Capitol building in Washington, D.C. has begun. A network of stainless steel rods is being...
Romanesque Reused
When Union Station in St. Louis, Mo. was built in the 1890s it was the world's largest railroad station. Having been abandoned by the railroads in the 1970s, it was reopened...
Clearing the Decks
Cathodic protection, an electrical-chemical process that prevents corrosion of steel rebars on bridge decks, is rapidly gaining acceptance by highway engineers and state highway departments....
Composite and Mixed Construction
Steel and reinforced concrete are frequently combined in composite or mixed structural systems. This combination generally results isn greater economy and safety than could be achieved...
Specifications for the Design and Construction of Composite Slabs and Commentary on Specifications for the Design and Construction of Composite Slabs
Composite slab construction is defined as a system comprising normal weight or lightweight structural concrete placed permanently over cold-formed steel decking in which the steel deck...
