ABSTRACT: The beam is an important element of the building structure. The failure of the beam can cause the collapse of the building elements attached to the beam. Which is very important when planning a beam element is material (concrete and steel). With the beam dimensions vary, can be obtained nominal beam moment (Mn) and the value of the beam material on Rupiah. The relationship between the nominal moment (Mn) and the Rupiah value can be displayed in the chart and made a linear gradient of the line. Based on result of analysis: improvement of bar dimension results nominal moment increased (3,674%) with sharp improvement every add diameter bar; but improvement quality of concrete results nominal moment inclined (3,28%) with declined every improvemet of concrete quality. Can be seen that the best is improvement of bar dimension to obtain the highest nominal moment (Mn).

Keywords: beams. the nominal moment (Mn). the quality of concrete (f'c)
