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...
Design and Installation of Prestressed Rock Anchors for Penstocks at the Sheldon Springs Project
A mini-hydroelectric project producing 25MW of power was recently completed near St. Albans, Vermont. The power conduit conveys water from the intake on the river to a bifurcation and...
Implementation of the Computer Analysis of Segmentally Erected Prestressed Concrete Bridges
Composite Bridge Structures
Reliability of Cracked, Prestressed Girders
For prestressed concrete structures in non-aggressive environments or where corrosion-protected prestressing strands are used, it may be possible to allow flexural cracking into the precompressed...
Applying the Time-Reliability Equation
This paper presents a methodology for rigorously including time-varying elements of reliability through the use of the time-reliability equation. An example reliability analysis which...
A Multilayered Model for Analysis of Composite Pipes
A multilayered model is developed to analyze the behavior of composite pipes, such as prestressed concrete pipe, to the combined effects of internal pressure and applied loads. The pipe...
Computer Aided Design of Partially Prestressed Beams
Guide for the Design and Use of Concrete Poles
Prepared by the Concrete Pole Task Committee of the Committee on Electrical Transmission Structures of the Structural Division of ASCE. This guide presents...

Tensegrity Structures: Aspects of Design and Analysis
The Design of Stays for Cable Stayed Bridges
Much of the R & D work done in the development of details for the modernized form of stayed girder bridges has been contributed by those practicing in the field of prestressed...
A Fatigue Study of Prestressing Strand
Strand fatigue data reported in the literature and also from recent tests were combined to form a data base of strand fatigue data which was analyzed using regression analysis techniques....
Innovations in Prestressed Concrete Structures
Prestressed concrete poles are probably the best choice for most transmission line structures. They have many advantages over structures made from other materials for both engineering...
Optimal Design of Continuous Prestressed Concrete Girders
Design of continuous prestressed concrete girders with possibility of parabolically varying depth in each span is formulated in the form of a mathematical programming problem. The design...
Analysis and Design of Prestressed Concrete Spun Poles
A microcomputer package for the analysis and design of prestressed concrete spun poles is described. The package, named PCPAD, consists of six programs each having a specific analysis...
