In this paper , numerical analysis of wide beams was presented. The proposed models were loaded with a static seismic load. Diverse models of reinforced concrete wide beams were studied numerically by ANSYS platform , and a parametric study was conducted. The studied parameters were web reinforcement percentage, tensile reinforcement percentage, and compressive reinforcement percentage. The values of tensile reinforcement percentage were ( 1.5% , 1% , 0.7 % , 0.3% ) of cross-section area, compressive reinforcement percentage were ( 0.8 , 0.6 , 0.5 , 0.4 ) of the tensile reinforcement ratio and web reinforcement percentage were ( 0.13 % , 0.067 % ). The influence of these parameters was studied on ductility, dissipation, toughness, stiffness and over strength. The results demonstrated that the studied parameters affected all these properties, and the smallest ductility was noticed in the wide beam ( B7 ) which has a value of 1.1
