In these days of continuing regulatory requirement changes and high interest rates, the engineering of structural modifications for operating nuclear power plants has taken on greater...
Intact Decommissioning Alternative for Nuclear Power Plants
Previous studies of decommissioning options for nuclear power plants have examined potential alternatives such as immediate dismantlement, entombment, and moth-balling. This paper describes...
Civil Engineering Challenge with Nuclear Waste
The planning, design and construction of the ground surface facilities for a nuclear waste repository involves civil engineering in many ways. The transportation of heavy, metal shielded...
Local Pressure in Ice-Structure Interactions
Two models for the determination of local pressures during marine ice or iceberg collisions with bottom-founded structures are presented. The first model is a two-dimensional analytical...
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
The 1984 novel
Classification of Human Errors
Error control should be a primary part of any risk control strategy. Classification of errors may serve as a basis for the systematic analysis to eliminate the causes and to reduce the...
Random Vibration Techniques
The paper presents a review of random vibration techniques for analyzing dynamic systems from the perspective of applicability to structural engineering. Problems involving linear or nonlinear,...
A Damage Function Using Structural Response Measurements
A new damage function is proposed that expresses seismic damage in terms of the range and number of cycles of plastic deflection experienced by a structure. This and other damage functions...
Finite Element Methods in Structural Safety Studies
The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method...
Concepts and Methods in Reliability-Based Structural Optimization
This paper presents an overview of the major concepts and methods used in reliability-based structural optimization. New formulations related to multicriteria optimization are developed....
Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...
Loads Due to Human Movements
The live loads due to human actions are random functions being modeled from data obtained from tests to determine load histories for the actions of individuals and small groups of people...
Probability-Based Load Criteria for Structural Design
Load criteria for use in limit states design of structures are developed using probabilistic methods. Statistical data on load and strengths are integrated by the reliability analysis...
Design Load Combination Factors
This paper reviews alternative load combination formats for ultimate limit states in codified structural design. The need for explicit consideration of load-time variations and random...
Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
Seismic Probabilistic Risk Assessment for Critical Facilities
Probabilistic Risk Assessment (PRA) for seismic events is currently being performed for nuclear power plants. The background on seismic PRA is presented along with a basic description...
Bridge Inspection by Dynamic Loading Technique
This paper describes, a case study of the evaluation of the structural integrity of a New York State Thruway bridge using the dynamic loading technique. The study was undertaken in a effort...
Use of Rayleigh Waves in Liquefaction Studies
The Spectral-Analysis-of-Surface-Waves method is a new seismic method for efficient determination of shear wave velocity in situ. Vertical impacts applied to the ground surface are used...
Aesthetics of High-Rise Building Structures
The structural aesthetics of high-rise buildings is discussed, with particular emphasis on building frames, individual members and on joints and connections. Examples are given of towers...
