The Validation Problem?Historical Developments
Validation of a probability consists of the estimation of the reliability of the probability. Validation is important when probabilities are based on data, rather than theoretical exercises....
Issues in the Validation of Probabilistic Methods
Probabilistic models are being used increasingly in safety assessments and regulatory decision-making. There is a need to relate the risks computed using these models to service data in...
Reliability-Based Design of Transmission Line Structures
Reliability-Based Design (RBD) is an emerging concept for the design of transmission line structures and holds the potential to reduce the cost of lines or increase their reliability....
Applications of Probability for Structural Analysis in the Nuclear Industry
Probabilistic techniques are being used as part of structural analysis in the nuclear industry to investigate various safety-related issues. Historically nuclear power plants have been...
Design and Construction of A 1/6 Scale, LWR Reinforced Concrete Containment
This paper summarizes the closely coordinated engineering and construction planning associated with the design and construction of a reinforced concrete containment model. Designed at...
An Overview of the Round-Robin Analysis of the 1:6-Scale Reinforced Concrete Containment Model
The results of nonlinear structural analyses of a 1:6-scale reinforced concrete model, which were independently conducted by ten different organizations, are briefly described and compared...
Development of a Test Validated Methodology for Predicting Concrete Containment Leakage
In the past several years, considerable research effort has been devoted by the Electric Power Research Institute and the U.S. Nuclear Regulatory Commission to the behavior of reactor...
Strength Evaluation of Existing Reinforced Concrete Structures
The load test as described in ACI 318-83 Chapter 20, entitled 'Strength Evaluation of Existing Structures,' was conducted at 60%, 80%, and 100% of the calculated...
Energy Approach of Earthquake-Structural Design Analysis
A new procedure developed from the earthquake energy concepts is presented in this paper. A short-squat building and a long-slender building are analyzed using the presented procedure....
Inelastic Response of Buried Pipelines Due to Landslide Effects
During earthquakes, a buried pipeline may experience significant loading as a result of large relative displacements of the ground along its length. Large ground movements can be caused...
Wind Effects on Loose-Laid Cladding Systems
Modern roofing systems for flat roofs frequently make use of rigid insulation boards, gravel and concrete pavers that are loose-laid on top of the waterproof membrane. The authors have...
Wind Performance of Asphalt Roofing Shingles
Pre-seal and post-seal wind resistance of asphalt roofing shingles is discussed. A test method for evaluating pre-seal wind damage is described. Wind tunnel testing results are presented...
Flexural Strength of Ultra-High Strength Concrete Members
Various proposals have been made for the pridiction of strength of high strength concrete sections. One of the most important parts of any strength computation procedure is the assumption...
Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...
Member Design Equations for a LRFD Wood Specification
A key step in the preparation of a load and resistance factor design (LRFD) based design specification for engineered wood construction is the selection of the behavioral equations for...
Some Design Considerations During Construction
Certain construction failures are discussed with associated design conditions leading to these failures. Some points of interest for engineers involved with construction equipment designs...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
Performance of Steel Sheet Pile Cellular Cofferdams
Steel sheet pile cells are often used as construction cofferdams for structures to be constructed in rivers. Examples of this type of construction include locks and dams, pumping stations,...
Codified Reliability for Structures During Construction
It is generally acknowledged that the most critical stage of a structure's lifetime is that of construction, leading to failures or locking in forces and deformations that...
Analysis of Glulam Lattice Dome
Glued-laminated timber (glulam) domes have become competitive in the engineering of large-span roof structures. Three-way glulam grid domes, such as the Triax and Varax domes, are particularly...
