Cracking Behavior Comparisons Between Normal and Fiber-Concretes
A comparative study of the cracking behavior of plain- and polypropylene fiber concrete was performed. Both high- and low-strength concretes were studied. Maximum and average crack widths...
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Testing of Reinforced Concrete Bridges for External Reinforcement
Several continuous reinforced concrete slab bridges were constructed in the 1950's with spans ranging from 30 ft. to 60 ft. Longitudinal cracks were observed in the tension...
Fiberglas Reinforced Plastic Rebars in Lieu of Steel Rebars
Fiberglass reinforced plastics have recently been introduced in the market in the form of rebars for concrete reinforcement. The light weight, corrosion resistance and non-magnetic properties...
Fatigue of Reinforcement in Partially Prestressed Beams
A summary of the findings of an extensive experimental program on the fatigue characteristics of partially prestressed concrete beams is described. It is observed that the stress range...
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...
Flexural and Shear Moduli of FRP Beams
The analysis and design of structures of pultruded fiber reinforced plastic (FRP), constant cross-section, commercially produced, beams is discussed in the context of a shear deformation...
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...
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...
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...
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...
Study and Design of Multi-Span Continuous Bridge
Multi-span continuous bridges which have been constructed in the Metropolitan Expressway Public Corporation are briefly explained. Some studies were carried out into their behavior. The...
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...
Nonlinear Finite Element Analysis of Experiments on Two-Story Reinforced Masonry Shear Walls
Nonlinear, static finite element analyses are being used for correlation with experiments conducted on one-story reinforced masonry shear walls, and for the prediction of and correlation...
