Effect of High Frequency Response on Fatigue of Offshore Structures
Welded steel specimens have been tested under several loading spectra to determine the effect on fatigue life of high frequency components in the psd of the stress or strain in the joint....
Low-Cycle Fatigue Reliability of Offshore Structures Subjected to Earthquakes
This paper develops and implements a methodology for predicting probabilistically the damage an offshore structure will experience in an earthquake. The analysis begins with the probability...
Concrete Strength-Quality Assurance
The usual criterion for establishing grades of structural concrete is the compressive strength measured in an arbitrary manner on a standardized specimen stored in a stipulated fashion...
Ultimate Strength and Deformation of RC Panels
In this study, twenty reinforced concrete panels have been tested under pure shear. Test results showed that the compressive strength of concrete strut was strongly affected by bond characteristics...
Analytical Model for RC Panels Under Cyclic Load
There are several existing constitutive laws for cracked concrete and steel in RC developed in Okamura laboratory. These models have been developed and verified through reversed uniaxial...
Wind Tunnel Testing of the Karnali River Bridge
An extended wind tunnel testing program of the erection procedures and the stability of the completed one-tower cable-stayed Karnali River Bridge was conducted with the help of full bridge...
Aerodynamic Improvements for Plate-Girder Bridges
This paper describes the application of wind tunnel tests on plate-girder cable-stayed bridges to ensure that the cross-section will not be susceptible to wind-induced oscillations. Information...
Retrofitting Aerodynamic Performance of Bridges
This paper is a review of aerodynamic retrofit techniques for long-span bridges. The discussion includes a description of the aerodynamic problems of static divergence, flutter, buffeting,...
Wood Diaphragms: Performance Requirements and Analytical Modeling
Wood diaphragms represent the principal mechanisms for resisting lateral loads in many light-frame buildings. While recent research has provided several mathematical models for predicting...
Lessons Learned from Dynamic Tests of Shear Panels
Thirteen 8-ft by 8-ft shear panels and fifteen 16-in by 18-in shear panels were tested dynamically at the Structural Testing Laboratory, Richmond Field Station, University of California,...
A Structural Analysis Model for Timber Shear Walls
A numerical modelling procedure for the non-linear analysis of timber shear walls is presented. The model includes the non-linear behavior of the connectors between the sheathing and framing,...
Looking at the Past
The story of bridge building is related through a look at the bridges of the past, from earliest bridges of record to the latest cable-stayed successes. Progress in bridge development...
Weathering Steel Bridges ? State of the Art
State of the art dissertations on materials that have been in commercial use for over a century are not likely to illustrate major new and innovative breakthroughs. Instead, the state...
Current Research and Future Developments
A review of current research projects at the National Science Foundation on bridge engineering are reviewed and discussed with respect to immediate and future impacts. A look into the...
Equilibrium-Serviceability Design of Hyperstatic P. C. Beams
A practical flexural design procedure for continuous prestressed concrete girders based on simulataneously ensuring specified margins of safety against both limit states of section and...
Analysis of Slender Prestressed Concrete Columns
This paper briefly describes an analytical model developed to study slenderness effects in prestressed concrete columns and walls and predict the characteristics of such members over a...
Guidelines for Application of FEM to RC Design
In this paper, the main contents of the guidelines for the application of FEM analysis to the design of reinforced concrete structures are presented. The guidelines were published by the...
Application Examples of FEM to Concrete Structures
The paper illustrates the practical application of the FEM by means of examples for plain/reinforced/prestressed concrete structures. These examples, including both global and local analyses...
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...
