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....

Overview of Programs at Sandia National Laboratories
This paper presents on overview of the containment integrity programs at Sandia National Laboratories. Companion papers at this conference give greater details about the construction,...

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...

Containment Model ? Test Program and Results
Sandia National Laboratories (Sandia) completed the testing of a 1:6-scale containment building for a Light Water Reactor (LWR) in July 1987. The containment building was made of reinforced...

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...

Stress Analysis of the Liner and Liner Anchorage System Near Penetrations in a Reinforced Concrete Reactor Containment
An overpressurization experiment was conducted on a scale-model of a reinforced concrete containment building. The test was terminated when tears formed in the steel liner. Virtually all...

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....

Optimum RC Member Design With Discrete Sections
This paper concentrates on the development of simplified yet effective algorithm for optimum reinforced concrete (RC) member design. After constructing the data base of predetermined reinforced...

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...

Fatigue Life Evaluation of Welded Structural Details in Steel Highway Bridge
Stresses in highway bridge members, fatigue crack propagation behavior and long life fatigue strength properties of welded members under traffic loadings and prediction of fatigue life...

Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...

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,...

In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...

Nonlinear Finite Element Analysis of Experiments on Two-Story Reinforced Masonry Shear Walls
Nonlinear, static finite element analyses are being used for correlation with experiments conducted on one-story reinforced masonry shear walls, and for the prediction of and correlation...

The Effect of Stiffness Degradation on the Three-Dimensional Seismic Response of Highway Bridges
This paper describes the effect of modeling of the inelastic pier behavior on the seismic response of three reinforced concrete bridges. Each bridge was analyzed twice once using a yield...

Bond and Dowel Action of a Main Bar in a RC Beam
The bond and dowel action are analytically treated independently on each other in most cases. The bond behavior may be, however, much affected by the dowel action in structural members....

Consequences and Achievement of Supplemental Damping for Improved Seismic Performance
An earthquake resistant design philosophy which relies upon increased stiffness and damping rather than increased strength and ductility has been investigated. The effect of adding supplemental...

Friction-Dampers for Economic Seismic Design
A novel structural system, which combines the strength and stiffness of a braced frame and energy dissipation capacity of the friction-dampers, has been used in the design of a reinforced...
