Early Age Strength Detection for In-situ Concrete
In recent years it has become increasingly beneficial to know the quality of concrete as soon as possible after it has been placed. This is especially true for high-rise concrete buildings...

Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...

Compressive Deterioration of Cracked Concrete
When shear behavior of reinforced concrete (R/C) members is to be simulated, the compressive strength and the stiffness reduction of cracked concrete must be taken into consideration....

Behavior of a Crack Under Reversed Cyclic Loading
The results of two series of basic experimental studies for opening and closing behavior in RC members are reported. For the first series, axial forces were applied to the specimens in...

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...

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...

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...

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...

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....
