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...

Development of Analytical Models for Reinforced Concrete
A computer program called WCOMR was developed to analyze the characteristics of RC walls subjected to reversed cyclic loading. The WCOMR comprises RC element idealization described by...

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...

Inclined-Cable Aerodynamics
A series of wind tunnel tests have been conducted to clarify the fundamental mechanism of the vibration of the inclined cables of cable stayed bridges. The influence of the cable orientation...

Lateral Force Distribution in Manufactured Housing from Full-Scale Testing
The research focused on the behavior of two manufactured 14 ? 66 ft houses under simulated wind loads. Extensive instrumentation was employed to insure the collection of data that would...

Panel-Sheathed Shear Walls ? Past and Future
In order for a building to resist the lateral forces caused by wind or earthquake, it is necessary that the building include a lateral force resisting system. When the walls are designed...

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...

Concrete Bridges � State-of-the-Art
The paper reviews the types of concrete bridge decks in most common use today, with particular emphasis on recent developments. Current trends in substructures and foundations are also...

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...

Study of Partially Prestressed Beams With Unbonded Post-Tensioning
Test on partially prestressed members with bonded Post-Tensioning started recently. Experimental information regarding partially prestressed members having unbonded post-tensioning is...

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...

Forces in Unbonded Tendons
A rational analysis procedure for the calculation of tendon forces in prestressed beams with unbonded tendons is discussed. The prestressing tendon is analyzed as a tight-string which...

Behavior of Externally Prestressed Concrete Girders
A new technique for prestressing concrete girders is presented. The girders are externally prestressed by epoxy-bonding fiber-composite plates to the tension flange of the cambered girders....
