On Aseismic Hybrid Control System
One type of hybrid control system is proposed for protecting tall buildings subjected to strong earthquakes. The hybrid system consists of a base isolation system connected to either a...
Practical Aspects of Structural Control
Several problems in the practical implementation of structural control are discussed herein. These problems include the prediction of the actual behavior of existing structures, mathematical...
Safety Improvement of Earthquake Loaded Structures Application of Semi-Active Control in Multi-Storey Buildings
This paper presents the studies for development of a new concept of aseismic design of structures. Basis of that engineering will be a structural optimization including elastic supported...
Active Control of Structures Under Stochastic Base Excitation with a Predominant Frequency
Active control of structures under stochastic base excitation is investigated. The synthesis of an active control system discussed in the study is based on the use of stochastic control...
On the Adequacy of Linearized Methods for Control of Nonlinear Bridge Oscillations
In this paper, control of nonlinear oscillations of a single-span flexible bridge with light damping is examined to improve bridge safety and reliability. The control forces are applied...
Reliability of Control Systems of Building Structures by Active Tendons
In this paper, a numerical assessment on the reliability of a control system of building structures by active cables is performed. Some control experiments on a 23-story shear-wall building...
Development of Reliability-Based Integrated Design-Construction Quality Assurance System of Penstock
A more rational design-construction quality assurance system is proposed by applying the concepts of the reliability-based design methods. By applying this system, the design level of...
Safety Plans for Buildings, Structures and Technical Facilities
Safety is an important quality feature and depends on all activities within the building process. The safety concept must therefore consider all phases of the building process, from the...
Probabilistic Traffic Load Models and Extreme Loads on a Bridge
This paper contains a summary of the intensive traffic measurements collected in France and Europe, and of the probabilistic distributions adopted for the main parameters. The evaluation...
Mode Truncation Effects on Flexible Space Structures
This paper deals with the problem of active vibration control of flexible space structures. The main difficulty associated with this problem is that the structure has infinite vibration...
Comprehensive Leak Detection Survey and Benefit/Cost Analysis
Fort Carson, Colorado was the site of a comprehensive leak detection investigation of the potable water system with the express purpose of quantifying the benefits to be derived by a military...
Valve Control to Avoid Column Separation in a Pipe
Maximum pressures in a pipeline can be reduced significantly by closing the valve in an optimal manner. Such an optimal valve closure policy may result in some situations in minimum pressures...
U. S. Nuclear Regulatory Commission's High-Level Waste Repository Licensing Program and Regulatory Strategy
The U. S. Nuclear Regulatory Commission (NRC) High-Level Waste Repository Licensing Program during the pre-licence application phase consists of activities in the following four areas:...
DOE Perspectives on the Regulatory Framework of the Civilian Radioactive Waste Management Program
Key statutes, regulations, and orders that govern the radioactive waste management program are identified. Current and recent regulatory activities are described in the areas of meetings,...
Preparing a Safety Analysis Report Using the Building Block Approach
The credibility of the applicant in a licensing proceeding is severely impacted by the quality of the license application, particularly the Safety Analysis Report. An incomplete, unintelligible,...
Implementation of NUREG 1318 Guidance Within the Yucca Mountain Project
The U. S. Department of Energy's Yucca Mountain Project is implementing a quality assurance program that fulfills the requirements of the U. S. Nuclear Regulatory Commission...
Evaluation of the Canadian HLW Disposal Program?Performance Assessment Aspects
The inception and development of the Canadian HLW disposal program are described, showing its basis in the multi-barrier system concept and noting the mechanisms in place for its evaluation...
Building of a Conceptual Model at the UE25-C Hole Complex
U.S. Geological Survey and Lawrence Berkeley Laboratory are attempting to construct a conceptual model of the UE25-c hole complex. An interdisciplinary approach is discussed where all...
Tomographic Geophysics for Better Subsurface Geologic Information
Geologic skepticism among engineers owes much of its origin to common ambigueties in geologic interpretations and the innate artistic aspects of geology and its related diciplines. Geophysical...
