Analysis of crack and strain states of high performance reinforced fiber concrete beams
Journal Title: Bulletin of the Military University of Technology - Year 2014, Vol 63, Issue 3
Abstract
The article presents the crack and strain states analysis of the reinforced high performance concrete beams with steel and polypropylene fibre. The beams were bent in the 4-point model. Research was carried out for three different beams with regard to the quantity and the type of reinforcement. The beam B1 was constructed conventionally with steel rods reinforcement. As regards beams B2 and B3, instead of the stirrups and the compressive rods, fibre reinforcement of variable fibre volume percentage was applied. For the analysis, a non-contact system for three-dimensional measurements of strain – ARAMIS was used. The analysis of the behaviour of the beams under static load was based on the measurements of crack and strain.[b]Keywords[/b]: reinforced concrete beams, high performance concrete, steel fibre, polypropylene fibre, ARAMIS system, crack state, strain state
