Behavior of Smart Reinforced Concrete Beam Column Joints by Using Shape Memory Alloy Reinforcement Under Repeated Loading
نویسندگان
چکیده
Using the super elastic materials in structures design is becoming very important research field because of their rare ability sensing around effect and reacting against mechanical thermal react. The major intent this designing smart concrete beam column joints reinforced by Shape Memory Alloy (SMA) bars. suggested systems use (super elastic) Pseudo Elastic (PE) react SMA as reinforcement after being subjected under monotonic repeated load. behaviors were explored experimentally using finite element simulation. In order to estimate load-displacement relationships these specimens study, Analytical models developed. A comparison was carried out it contained that variation percentage flexural (25%, 50%, 75%) total substitution get a clear on failure load ultimate displacement with different ratios. Finite Element developed software ABAQUS. have been checked experimental results terms top reinforcement. showed reasonable response. Where decreased bars 75% ) about (50.51%, 28.32%, 38.15%) respectively, case static loading (20.7%, 10.7%, 9.3%) respectively loading, deflection increasing (1.2%, 8.4%, 0.36%) (9.6%, 5.28%, 10.9%)

متن کاملTime-Dependent Behavior of Reinforced Concrete Beams under Sustained and Repeated Loading
Abstract—The current study aims to highlight the loading characteristics impact on the time evolution (focusing particularly on long term effects) of the deformation of realized reinforced concrete beams. Namely the tension stiffening code provisions (i.e. within Eurocode 2) are reviewed with a clear intention to reassess their operational value and predicting capacity. In what follows the expe...

Structural health monitoring is an important aspect of maintenance for bridge columns in areas of high seismic activity. In this project, recently developed piezoceramic-based transducers, known as smart aggregates (SA), were utilized to perform structural health monitoring of a reinforced concrete (RC) bridge column subjected to pseudo-dynamic loading. The SA-based approach has been previously...
متن کاملSuperelastic Behavior under Cyclic Loading for Coil Spring of Ti-Ni Shape Memory Alloy
The superelastic behavior of coil springs of a Ti-Ni shape memory alloy was investigated using loading-unloading cycling tests under isothemal temperatures. The effects of the Ni content and shape memory treatment temperatures on the cyclic behavior in the superelastic deformation were investigated. The deformation behavior within the elastic region of the parent phase scarcely changes during t...
