Concrete Shell Design for Membrane Stress
A methodology is presented which covers the design of reinforced concrete shells for membrane stress. The methodology follows the strength design method of the ACI 318-83 Building Code...

Large Reinforced Concrete Active Reclaim Silos
The design and construction of large reinforced concrete shell silos used to provide economical short-term protected storage for coal and lignite in the active reclaim systems of power...

Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...

Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...

Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...

Projectile Penetration Into Reinforced Concrete and Steel Targets
This paper presents brief preliminary results of a research program sponsored by the Air Force Weapons Laboratory (AFWL) to investigate the interaction of 30-mm cannon projectiles with...

Engineers in Court
Engineers who like debating often serve as expert witnesses. Though many avoid forensic work because they find lawyers intimidating, some like the challenge of explaining engineering principles...

A Data Base System for Hazardous Materials Transportation
This paper reports on a hazardous materials transportation study conducted in Arizona. Two types of surveys were conducted: hazardous waste shipments for 1983 and 1984 compiled from manifests;...

Procedures for Evaluating TSM Projects
The constraints of limited funding, increasing demand and environmental impact have led to an increase in Transportation Systems Management (TSM) improvements on surface transport systems....

Simulation of Intersections During Reconstruction
In order to make computer simulation of intersections more appealing and easier to use, and interactive, menu-driven micro-computer program, called INTERCON (Michalopoulos and Plum, 1986),...

Photogrammetric Analysis Using a Personal Computer
In many cases, photographs of the accident scene taken soon after the event contain visible evidence of road marks and/or debris. By the time the case reaches the accident investigator/reconstructionist,...

Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...

Building Structures
This volume contains over forty papers from thirteen sessions of Structures Congress '87. The papers include a variety of topics on the overall behavior and design of buildings...

Teleport: New Wave Engineering
Between $600 and $700 million will be spent on teleports now being planned in the U.S., presenting interesting challenges to civil engineers. Just as airports and seaports serve as collection...

Connecticut: A Success Story
The Connecticut Department of Transportation (ConnDOT) had warned the state legislature that its highways and bridges would continue to deteriorate without increased funds for inspection,...

Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...

Preliminary Design and Construction Plan for an Ocean Wave Energy Conversion System
A preliminary design and construction plan for a prototype wave energy conversion system is described. While the design methodology and construction procedures are intended for generic...

Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....

Generating Alternative Financing Models for Urban Transportation: An Application of the Idea Machine
The purpose of this research was to examine how localities in Virginia could obtain funds for urban highway construction and maintenance, and indirectly, for mass transit from the so-called...

Impact Fees: Florida's Link Between Growth, Road Improvements, and Financing
Impact fees are one mechanism by which local governments can obtain additional revenue needed to construct major roads demanded by the consequences of new development. In Florida, the...
