NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...
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...
Wood Diaphragms: Performance Requirements and Analytical Modeling
Wood diaphragms represent the principal mechanisms for resisting lateral loads in many light-frame buildings. While recent research has provided several mathematical models for predicting...
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,...
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...
Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...
Load Combinations for LRFD With Wood Construction
Probability based limit states design for wood construction is complicated by the fact that wood is a natural material with large variations in mechanical properties and is sensitive to...
