چکیده
Composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. In this paper, after modeling couple beams with and without steel plates with F.E methods and calibration the models with experimental results, effects of parameters such as thickness, height, length and yielding strength of the steel plates located in concrete couple composite beam have been investigated on the ductility, energy dissipation and capacity. The results were illustrated that if the plate thickness would be increased by four times, ductility and energy dissipation capacity were decreased ۱۵.۶ and ۱۴.۷ percent and also loading capacity was enhanced up to ۲۵ percent, respectively. And also the plate height and length didn’t have influence on above mentioned parameters. Furthermore, by ۸۰ and ۲۸۰ percent enhancement in yielding plate strength, ductility and energy dissipation capacity were decline ۱۰.۸ to ۲۳.۹ and ۸.۹ to ۲۱.۷ percent and also ۱۹, ۳۳ percent enhancement in loading capacity was happened.کلیدواژه ها
