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...
Members Subjected to Torsion Combined with Other Actions
The combination of torsion with bending and shear (T-M-V) in members with both transverse and longitudinal reinforcement is the most commonly encountered combination in practical cases....
Detailing and Design Examples for Torsional Members
The nature of the internal force flow in a concrete member subject to torsion brings about both longitudinal and transverse force components. The resulting tension brought about by the...
Evaluation of the CON-ARCH reinforced Concrete Buried Arch System
Final Report
This report summarizes the evaluation of the Con-Arch culvert system marketed by Hunter Contracting, Co. of Tucson, Arizona. The evaluation consisted of computer analysis and field testing of two Con-Arch...
Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...
Use of Fiber Reinforced Polymer Composites as Reinforcing Material for Concrete
Although the potential of continuous fiber reinforced polymers (FRPs) was recognized more than 50 years ago, bottlenecks such as vulnerability to static fatigue, ultraviolet radiation,...

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...
