Torsion of Reinforced Concrete -A Historical Overview
The story of torsion of reinforced concrete must start with the French professor, C. L. Navier. In his landmark book (Navier, 1826) he rigorously derived the first rational theory for...

Overview of Structural Behavior of Members Subjected to Torsion
The torsion strength of concrete beams depends on many factors, such as the amount of reinforcement, the volumetric ratios of longitudinal and transverse steel bars, the concrete strength,...

Advances in Analytical Modeling of Torsional Members
The basic formula for calculating the torsional strength of reinforced concrete members was developed by Rausch (1929) using the space truss concept. Unfortunately, Rausch's equation may...

A Concerted Effort
With aid from the National Science Foundation, 15 Universities across the country have expanded and upgraded their earthquake simulation research facilities. These resources have now been...

Performance-Based Criteria for FRP Products and Materials
In most ways, fiber-reinforced polymer (FRP) structures perform similar to wood and steel structures. There are, however, certain differences and these differences are described in this...

Suggested Guidelines for Performance-Based Tests
Although several standard tests are cited in this chapter, these tests are not designed specifically for fiber-reinforced polymer (FRP) overhead line structures. There are, in fact, no...

Quality Assurance
The user is responsible for ensuring the quality of products purchased. Therefore, the user of fiber-reinforced polymer (FRP) products determines the level of quality that will be accepted....

Assembly and Erection
This chapter is intended to provide recommendations on transporting, handling, assembling, and erecting fiber-reinforced polymer (FRP) poles. An important consideration is that FRP poles...

In-Service Considerations
Generally, little or no preventative maintenance is required on fiber-reinforced polymer (FRP) poles. This chapter discusses factors that could affect the performance of FRP poles after...

Loading Requirements for FRP Poles Utilized in other than Utility Line Applications
