High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...
White Steel for Osaka Bay
Wind, earthquake and aesthetics were the design determinations for Japan's Higashi-Kobe Bridge. The designers also had to consider the man-made bay infill site and a directive...
New Support for Pin-Hanger Bridges
To promote safety of their bridges, many state highway departments are considering ways to add auxiliary support to existing pin-hanger bridges. The Pennsylvania DOT and its open-end consultant...
Tomorrow's Toll Road
Techniques using automatic vehicle identification (AVI) currently provide the most efficient form of electronic toll collection. Several systems have been installed in the U.S. in the...
Designing for Corrosion Control
This presentation will discuss designing from several aspects: a. Designing of the item to lessen the affects of corrosion. b. Selection of non-corrosive materials in the designing process...
Recirculation Piping Replacement Project at Dresden Unit 3
This paper discusses the Recirculation Piping Replacement Project performed at Dresden Unit 3 during 1985 and 1986. It describes several of the technical and administrative problems associated...
A Computerized Completion
The original designers of the 1.6 million sq ft Fillmore Center in San Francisco (its largest mixed-use development project in 20 years) had specified a large amount of steel reinforcement...
Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...
Verification of Approximate Methods of Structural Analysis
Sophisticated computer programs for the determination of the effects of instability on the inelastic stress resultants in steel structures will appear to be 'black boxes'...
Certifying the TN-BRP and TN-REG Transportable Storage Demonstration Casks
The U.S. Department of Energy (DOE) has obtained U.S. Nuclear Regulatory Commission (NRC) certification to transport two transportable storage casks for a demonstration project. Because...
Effect of HNO3-Cerium(IV) Decontamination on Stainless Steel Canister Materials
Stainless steel canisters will be filled with vitrified radioactive waste at the West Valley Demonstration Project (WVDP), West Valley, NY. After they are filled, the sealed canisters...
Modelling Studies for the Assessment of the Advanced Cold Process Canister
The Advanced Cold Process Canister (ACPC) is a new concept for the encapsulation of spent nuclear fuel for geological disposal. It consists of steel canister encased in a copper overpack....
A PC-CAD System for Prefabricated Steel Bridges
A microcomputer-aided analysis and design system for prefabricated steel bridges is presented in this paper. The system was customized to perform all the required engineering to analyze,...
Discrete Optimal Design of 3D Frameworks
The paper describes a discrete optimization method for the least-weight design of three-dimensional (3D) steel building frameworks. The method involves the coordinated application of structural...
Strategies Which Permit Multiple Discrete Section Properties per Member in 3D Frameworks
Strategies for discrete structural optimization of 3D steel frames with coupled section properties are presented. These strategies include linearized branch and bound, simulated annealing,...
Structural Optimization to Limit Natural Periods
It is necessary to limit the natural periods of some structures to control their response to dynamic loads. Floor systems with natural periods greater than approximately 0.15 seconds may...
Data Modelling for Steel Frame Structures
The first step to automate any facet of structural engineering is developing a suitable data representation upon which the computer program will operate. However, there is no standard...
Boston's Sewage Outfall
The centerpiece of the Boston Harbor cleanup plan will be the sewage plant on Deer Island, which will treat water from 43 municipalities in the Boston metro area�500 mgd to start. In order...
A Logical Variable Approach to Water Supply Reliability
The calculation of the reliability that water will be available at a demand point in a distribution network is complicated by the redundancy of paths from the source to the point. The...
Stochastic Finite Element-Based Reliability Analysis of Dynamically Loaded Frames
This paper presents the use of the Stochastic Finite Element Method (SFEM) for reliability analysis of steel frames subjected to dynamic loading, in the context of modal superposition....
