No Feet of Clay
The methods of dealing with hazardous waste are evolving. At Superfund sites, for instance, excavation and removal was once the popular choice for treating pollutants, but stabilization...
Simulated Effects of Climatic Change on Runoff and Drought in the Delaware River Basin
Various projection of climatic change were applied to watershed models of the Delaware River basin. Simulations indicate that a warming could reduce annual runoff by as much as 25 percent...
Corps of Engineers Drought Management Experiences
The drought of 1988-89 was one of the most severe on record for many regions of the United States. Its severity can be measured in terms of the areal extent of hydrologic impact, the record...
Water Jets Fight Silt
In the largest U.S. application to date, an array of hydraulic jets is being used to scour a ship berth at the Port of Grays Harbor on the coast of Washington. The system has been in place...
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...
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...
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...
Local Buckling Behavior of Plate Elements
In the elastic post-local buckling range, the stress distribution across the width of compression elements of light gauge steel shapes is nonlinear. For code implementations, these stress...
New Concepts in Transmission Line Design
Committees of the American Society of Civil Engineers have been in the forefront on updating design guides to address improved procedures for conventional latticed towers, formed-plate...
New Outlines for 500 kV Transmission Towers Using Cold-Formed Shapes: The Experimental Line of the American Electric Power Research Institute
The use of cold-formed steel members, in electrical transmission towers, is actually a feasible, reliable and economical solution. The EPRI experimental line is an example of the newest...
Sizing Techniques for Lateral Bracing
Techniques for determining the size of lateral bracing members in multi-story steel buildings are presented and discussed. Because the design of such bracing is usually controlled by deflection...
The Design of Diagonal Cross-Bracing
The results of an analytical and experimental study on the behavior of simple and double diagonal cross-bracings in vertical stiffening trusses and in built-up open web beams are presented...
Unistrut Space Frame Systems and Their Application
A review of the application of latticed structures is presented. The design and construction of space frames is dependent upon the availability of adequate connection systems to realize...
Design Issues in Steel Buildings
The Committee on Design of Steel Building Structures of the Committee on Metals of the Structural Division of ASCE was formed in 1981, with the express purpose of studying problems that...
Floor Vibrations ? Tips for Designers
The purpose of this paper is to suggest a number of practical concepts which can be used to improve the performance of floor systems subject to occupant induced motion from either walking,...
Evaluation of the Rotation Capacity of Wide-Flange Beams Using Shell Finite Elements
Numerical simulation can be useful for planning of experimental tests, performance of parametric studies, and achieving an understanding of complex three-dimensional behavior that may...
Stablity Considerations in the New E&CS Building
The new Engineering and Computer Science (E & CS) building at California State University, Sacramento (CSUS) is a five-story structure characterized by two shear walls in the east-west...
Stability Analysis in Bracing and Support Design
A post-buckling stability analysis is carried out for struts with multiple elastic lateral supports. Both hinged-end and fixed-end conditions are considered. A criterion of sufficient...
Lateral Buckling of Beams: General Considerations
The paper presents a solution for the elastic, lateral-torsional buckling of beams under unequal end moments using Worthington's method of superposition of modes involving...
