Elastik temel üzerinde polipropilen elyaf takviyeli kiriş davranışının incelenmesi

Polypropylene fibre reinforced beam is a new successful material in improving the behaviour of beam concrete - especially when it combines with the conventional Polypropylene reinforcement- there's an absence of codes and standard that predict and estimate the real punching capacity of the panels containing polypropylene fibre especially when it is subject on elastic foundation. Many types of reinforced concrete beams have been analysed and the solution of finite element was supported with the data from lab work. A number of parametric works were created. The influence of various key finite element and material factors, such as mesh distribution, density, and mesh size effects on the accuracy of three-dimensional finite element model outputs, was investigated. The load-deflection curves at the centre of the polypropylene fibre reinforced beam, as well as the yielding reinforcement occurrence, indicated that the behaviour of the modelled specimen may be elucidated by the load-deflection curves at the centre of the comparable traditional concrete beam.
