Fatigue and Fracture Evaluation of Riveted Bridge Members
Among the major concerns of bridge engineers today are the fatigue damages that have been accumulated in riveted members and the safety of riveted structures. Many of these structures...
Fatigue Evaluation of a Riveted Railroad Bridge
An 83 year old railroad bridge was analyzed for fatigue based on historical records such as the original schedules. Based on the number of cycles to date, corresponding to an effective...
Fatigue Behavior of Steel Connection Angles
A method for predicting the fatigue behavior of flange angle elements is presented. The primary emphasis herein concerns an analytical approach for evaluating the fatigue life of flange...
Fiber Composite Materials in an Arctic Environment
This paper summarizes a study on the behavior of light-weight structural composite materials in cold environments. Results are presented for two composite materials: fiberglass-epoxy and...
Water Transport in Limestone by X-Ray CAT Scanning
The transport of water through the interior of Salem limestone test briquettes can be dynamically monitored by computer aided tomography (commonly called CAT scanning in medical diagnostics)....
Enhancing Concrete Durability by Treatment with Sealers
This paper summarizes some of the research which has been undertaken on sealers for hardened concrete during the last ten years at Wiss, Janney, Elstner Associates. Inc. The research used...
The Use of Penetrating Sealers on Concrete Bridge Decks
Acceptance criteria for Penetrating sealers is shown. Penetrating sealers can be used as cost effective preventive maintenance for bridge deck concrete in northern climates. Factors affecting...
Use of Copper Slag for Construction Purposes
Standard laboratory test results on the fine- and coarse-grained fractions of a copper slag have been presented. Based on the results of these tests, the possible use of the fine fraction...
Predicted Fatigue Life Behavior of Stay Cables
Monte Carlo simulation results are used to illustrate the relationship between the fatigue lives of short prestressing strand test specimens and long strand stay cables. Long stay cables...
A Summary and Review of Fatigue Data for Mechanical and Welded Splices in Reinforcing Bars
Published reports pertaining to fatigue tests of welded and mechanical splices in reinforcing bars were reviewed. It was observed that most specimens fractured in the reinforcing bar adjacent...
The Fatigue Performance of Welded Joints in a Marine Environment
The fatigue lives of plate-plate, pipe-plate, and tubular welded joints tested in seawater under free corrosion, optimum cathodic protection and cathodic overprotection measured in the...
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...
