Experimental Research of New Tram Track Construction Operating Fatigue Capacity

Abstract

The results of dynamical fatigue testing of natural tram track fragment are presented. The fibrous concrete (foundation) was used in track superstructure, the rubber pads “PREFArails” were used for noise and vibration reduction. The cycle testing results analysis demonstrated that “PREFArail” pads ensure the overall structure operability over not less than 25 years without repair. The recommendations for pads and fibrous concrete foundation use on tram tracks in Saint-Petersburg were given.

Modeling of Deformation and Fracture of Concrete Structures with FRP Reinforcement

“…Development of FRP bars as reinforcement of concrete structures was started in USSR in early sixties [1,2] and in USA in eighties [3,4]. The aim of the work is experimental and numerical investigation of FRP behavior in the bended concrete structural elements and comparison of carrying capacity of beams reinforced by two types of FRP with different windings (flat and spiral), which previously analyzed on bond behavior with concrete [5,6].…”
