Effect of Lateral Restraint on Short- and Long-Term Behavior of Pin-Bearing Pultruded FRP Connections
This paper reports results from an experimental investigation to examine the behavior of E-glass/polyester pultruded fiber-reinforced polymeric (FRP) materials subjected to short- and long-term single pin-bearing loads. The effects of lateral applied torque on the measured bearing strength of the connection are evaluated. Based on these results, pin-bearing creep tests are carried out at specific lateral restraint conditions and various load levels for time durations of up to 1,000 hours. The short-term test results indicate that an increase in lateral restraint increases pin-bearing strength significantly. The creep tests indicate that the perceived increase in bearing strength achieved by providing lateral restraint is lost or reduced significantly over time under sustained loading.
