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...

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,...

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...

Parametric Analyses of RC Shear Walls by FEM
In this paper, nonlinear behavior of reinforced concrete shear walls is studied by using the finite element analysis. We applied numerical analyses to a wide range of parameters, such...

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....

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...

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...

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...

Field Observation of Aerodynamic Responses of a PC Cable-Stayed Bridge During Its Erection
Recordings were made of the response of a PC cable-stayed bridge during erection and the wind velocity at erection site. These recordings were analyzed to provide estimates of the characteristics...

Wind Resistant Design Manual for Highway Bridges
The new wind resistant design manual for highway bridges has been required recently in Japan. The working group was organized in the Japan Road Association is 1984 to prepare the manual....

Codification of Wind Effects for a Long Span Suspension Bridge
Construction of the Akashi Kaikyo Bridge, which will cross the Akashi Kaikyo Straits with a shore-to-shore of approximately 4 km, started in spring of 1988. Firstly discussions on the...

Bridge Loading Evaluation for Limit States Design in Japan
Some statistics regarding bridges in Japan are firstly explained. Next, the limit states design which will be introduced in 1995 for highway bridge design specification in Japan is briefly...

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...

Evaluation of Bridge Safety and Remaining Life
