Cables and Flexible Pipes in Contact with Sea Floor
Flexible offshore systems can be analyzed by a number of different techniques. The techniques described herein fall in the general category of finite element methods. Special cable elements...

An Overview of Structural Reliability Methods
Recent developments in structural reliability theory and better availability of load and strength data suggest that reliability-based design (RBD) methods should be considered as a practical...

Transmission Line Structure Loading
This paper outlines specific procedures for determining loads on transmission line structure systems that can be used in the reliability based design or assessment of components of these...

Improved Techniques for Assessing Structures
The Electric Power Research Institute (EPRI) has specially designed and equipped the tower testing station located within their Transmission Line Mechanical Research Center (TLMRC) near...

Assessment of Conductors
This paper deals with the mechanical integrity of conductors after several years in service and discusses current innovative conductor designs which benefit the structural designer working...

Transmission Line Insulator Assembly Reliability
Transmission line insulator assemblies made up of ceramic or composite insulators and associated hardware are used to mechanically support and electrically isolate energized conductors...

Cambering of Steel Beams
Cold cambering with force in the fabrication shop is an effective and economical method of compensating for deflections of composite beams. Typical beams should be cambered for dead load...

Effects of Fabrication on Local Stress Conditions
Factors connected with fabrication that impact on the behavior of structural steel members are reviewed. Residual stresses that result from basic steel production and subsequent fabrication...

Effect of Imperfections on Structural Performance
This paper briefly describes the effect of initial crookedness and residual stress on the behavior of steel members. Both imperfections are unavoidable consequences of modern fabrication...

Engineering Design Concerns Regarding Steel Fabrication
The precise fabrication of structural steel pieces is an essential part of the process leading to the satisfactory erection and connection of the individual steel elements into the final...

Repair and Rehabilitation of Damaged Steel Flexural Members
In earlier years, the primary method for repairing steel flexural members was to replace the member. However, with the cost of labor and material increasing dramatically over the last...

Six Story Tubular Atrium
The author designed an atrium structure with two stair-stepped atriums placed at 45? to the tower 'Figueroa at Wilshire' in Los Angeles, California. This structure...

Toronto Skydome Retractable Roof Stadium?The Roof Concept and Design
The Toronto SkyDome is a first of its kind sports stadium with a retractable roof which results in, essentially, a fully open air stadium with the roof fully retracted. This unique roof,...

The Fabrication and Erection of the Minneapolis Convention Center
A new convention center is part of the City of Minneapolis' successful plan to maintain an economically strong downtown core. It is the latest addition to a list of civic...

Changes in Tubular Design Codes
This paper summarizes a number of changes in design provisions for tubular structures that have recently been adopted. These are the result of a number of research advances concerning...

Effective Length Factors for Type-PR Frame Members
The effects of PR-Type connections and loading arrangement on frame stability and the effective length factor of columns are evaluated for portal frames and three-story three-bay frames...

Buckling Design of Vierendeel Reticular Shells
Double layer reticular shell structures carry very little transverse shear, thus, it may be appropriate to substitute the inter-layer diagonal members with 'space'...

Beam-Supported Slabs Subject to Edge Loading
A model is presented which allows a designer to estimate stiffnesses required to provide a given critical buckling load in beam-supported slabs subjected to biaxial edge loading, such...

Behavior of Plates Under Partial Edge Loading
This paper addresses one of the common problems in designing thin-walled members, the ability of the shape to accommodate in-plane concentrated loads. Specific areas in which the problem...

Stability of Plates Under Eccentric Edge Loads
A linear finite element analysis was conducted to study the stress distribution in the web and the flange when the beam is subjected to a patch load applied in the plane of the web or...
