Summary: Although high performance concrete (HPC) is commonly used, its properties are not known as much as the properties of ordinary concrete. Indeed, most of equations, rules andsuggestions given in codes used in the design of reinforced concrete and prestressed concrete structures are developed from the data obtained from experimental studies made on concretethat have a strenght of less then about 50 MPa. Especially, the reason of the monolotical structure and non-lineer-elastic behaviour of concrete, the equations used for design, aren’tconvenient for the HPC members. Most structural members have been affected by torsional effects for the reasons of thenonsimetrical loadings and structural geometries. Genarally these effects are not effective as much as the other sectional effects in a member. Torsional resistance are able to increased byusing HPC. But, the main purpose of these study is to investigate of whether torsional resistance is able to increased or not by using different reinforcement.The study consists of five chapters. In the first chapter, genereal information is presented. In second chapter, experimental setup, producing high performance reinforced conrete beamsand torsion mechanism are desciribed. In the third chapter, experimental findings are presented by graphics and photos, some examines are realized on findings, and a newapproximation is presented to predict torsional moment in this chapter. The conclusions drawn from the results of this study and suggestions are presented in fourth chaper. This lastchapter is followed by the list of refences. The conclusions obtained from this study showed that, different reinforcementarrangements change the behaviour of the HPC in pure torsion. While some arrangements are change the strength and another some are change the deformation behaviour. Furthermore,a new formulation is proposed to predict the torsional moment capacity of beams made of HPC.Key words : High Performance Concrete, Torsion, Pure Torsion, Torsional Moment, Reinforcement Arrangement. |
