An Integrated Approach to Structure and Control Design of Space Structures
In this paper the authors have investigated the effect of passive damping on the optimum structural design with active controls. The minimum weight design is obtained by imposing the constraints...
Optimum Seismic Structural Design with Tendon and Mass Damper Controls and Random Process
This paper describes the optimization of structural weight for seismic structures implemented by active control systems. The instantaneous open-loop optimal control algorithm is used for...
Structural Optimization Under Conditions of Uncertainty, with Reference to Serviceability and Ultimate Limit States
Probability concepts and methods are rapidly gaining ground in the search for more rational approaches to structural optimization. Under conditions of uncertainty, the risk of unfavorable...
Reliability Constraint on Optimum Design
The purpose of the paper is to emphasize the importance of the probability concern on optimum design work. The probability of failure of the structure can be considered as one of the optimum...
Optimization for Overall Stability
This paper synthesizes design of trusses for linear stability constraint as an optimization problem where linear stability is defined as a generalized eigenvalue problem and presents a...
Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
Bidirectional Seismic Response of Simple Structures
For design purposes it has been common to consider that seismic excitations act in one direction at a time. Analytical studies over the past decade have indicated that this may not be...
Study of the Collapse of a Reinforced Concrete Model Structure Under Simulated Earthquake Motion
The collapse, under simulated earthquake motion, of a multistory r/c frame structure with columns flexurally weaker than beams (SBWC) is studied. A small-scale model, comprising parallel...
Water Project Design and Safety: Prospects for Use of Risk Analysis in Public Sector Organizations
After offering some initial definitions, the authors will describe a highly structured model of risk analysis and water resources decision making in the public sector. The primary emphasis...
Impacts of Risk-Based Analysis on Current Design Practices
A summary of hydrologic design standards used by selected federal agencies for the safety evaluation of dams is presented. A computational procedure is outlined to develop hydrologic design...
Factory Chic
Developers of the International Design Center of New York have recently spent $163 million to convert an unused chewing gum factory and a former battery plant into a showcase for New York...
Capitol Hill Infrastructure Advice
The National Public Works Improvement Council must report to President Reagan and the Congress by early 1987 on ways to maintain and improve the nation's infrastructure. One...
Rehabbing for Reuse
Case histories of four building rehabilitation projects highlight special challenges to their structural engineers. The Lits Building, Philadelphia, is a collection of eight structures...
Uncertainty and Conservatism in the Seismic Analysis of Nuclear Facilities
Traditionally, seismic analysis and design of nuclear power plant structures are performed using deterministic procedures. In order to address the issue of the likelihood of failure, probabilistic...
A Study of Exterior Facades?Problems and Solutions
The quality of the exterior facades of a building is important to maintaining aesthetic image, protecting the interior environment from infiltration of heat, cold, moisture, wind, and...
The Basics of Water-Resistant Brick Walls
Water-resistant masonry walls of burned clay or shale brick are the result of a conscious effort to produce them, by everyone involved in their creation. Furthermore, owner maintenance...
Structural Monitoring Concepts for Arctic Pipelines
Terrain instabilities producing differential soil movements are the predominant features affecting the structural integrity and design of buried pipeline systems in the arctic. Current...
