Effect of Temperature on the Load-Carrying Capacity of Fiber Glass Reinforced Plastic Beams
This paper describes an experimental investigation into the behavior of two T shaped beams made of fiber glass reinforcement and polyester or vinylester binders. Tests were performed at...
Development of High Strength Composite Cables
Fiber reinforced composite materials offer significant advantages over conventional materials, for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages...
Application of Fiber-Composites in Civil Engineering
Two potential applications of Glass-Fiber-Reinforced-Plastics (GFRP) in civil engineering type structures are investigated: (1) GFRP rebars in concrete beams; (2) strengthening of concrete...
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...
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....
Shear Strength of P.P.C. Beams
50 beams of partially prestressed concrete were tested and 82 data of the ultimate shear-strength were obtained. Based on these results, this paper studies the effects of the degree of...
Overview of Programs at Sandia National Laboratories
This paper presents on overview of the containment integrity programs at Sandia National Laboratories. Companion papers at this conference give greater details about the construction,...
Stress Analysis of the Liner and Liner Anchorage System Near Penetrations in a Reinforced Concrete Reactor Containment
An overpressurization experiment was conducted on a scale-model of a reinforced concrete containment building. The test was terminated when tears formed in the steel liner. Virtually all...
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...
Energy Approach of Earthquake-Structural Design Analysis
A new procedure developed from the earthquake energy concepts is presented in this paper. A short-squat building and a long-slender building are analyzed using the presented procedure....
Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...
Dynamic Response of a Building with Dual System
The paper presents the dynamic response of a 30-story building with dual system consisting of cross-bracing and beam-column moment resisting frames. Two types of beam-column connections,...
Optimum RC Member Design With Discrete Sections
This paper concentrates on the development of simplified yet effective algorithm for optimum reinforced concrete (RC) member design. After constructing the data base of predetermined reinforced...
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...
Current Bridge Research at Iowa State University
For the past 20 years the majority of the structural engineering faculty in the Department of Civil and Construction Engineering at Iowa State University (ISU) have performed research...
Performance of Steel Sheet Pile Cellular Cofferdams
Steel sheet pile cells are often used as construction cofferdams for structures to be constructed in rivers. Examples of this type of construction include locks and dams, pumping stations,...
