Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...

Seminar Summary and Research Needs
All the papers presented in the technical sessions of the seminar are summarized and, in some cases, commented upon. The needed research in composite and mixed construction is described....

Binding and Bonding Concrete to Composite Columns
Composite interaction between concrete encasement and structural steel shapes is limited unless lateral ties and/or mechanical attachments insure such interaction until desired strength...

High Strength Steel
A Wall Street Journal story in January 1984 described a number of bridges, buildings, automobiles, buses and other structures made of high-strength...

A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...

The Engineering Aesthetics of Tall Buildings
The Proceedings of a session on the Aesthetics and Design of High-Rise Buildings at the ASCE Convention in Denver is included in its entirety. The session was chaired by Lynn Beedle and...

Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...

Effects of Vehicles on Buried, High-Pressure Pipe
The mechanical effects of selected types of traffic on buried, high-pressure steel pipe are examined. Particularly considered is a section of the Colorado Interstate Gas (CIG) pipeline...

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...

Comparing Flood Stage-Discharge Data?Be Careful!
A long term stage-discharge record is extremely valuable data. However, simplified applications of long term records to draw sweeping conclusions about man's effects should be avoided,...

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...
