摘要

The use of fiber-reinforced polymer (FRP) materials for bridge construction has been rapidly growing in Russia over the past few decades. During the 1960s and 1980s, pioneering research was conducted in Russia, leading to the development of the first global design guidelines for FRP-reinforced bridges in 1978. This was followed by the construction of several bridges using prestressed FRP reinforcement during the 1970s and 80 s. This article discusses the technical aspects and details of three such bridges, completed in 1975, 1981, and 1989. Those bridges constructed with usage of GFRP prestressed bars diameter 6 mm. It provides an overview of their current condition and discusses the results of testing specimens extracted from these structures after 40 years in service. The article also discusses the use of FRP materials in modern Russia. Thus, pedestrian bridges with load-bearing span structures made of pultrusion profiles were erected. A bridge across the Moscow-St. Petersburg highway was built using CFRP ropes, as well as GFRP reinforcement in reinforced concrete slab.
