ABSTRACT Reinforced concrete is a composite element consisting of concrete and reinforcing steel planted in concrete. The main properties of concrete are strong in compressive forces but weak in tensile forces. Reinforcing steel in concrete serves to cover these weaknesses, namely resisting tensile forces and some compressive forces. The strength of the concrete itself is based on mixed proportions, conditions of temperature and humidity where the concrete will harden. Plates flates is the right choice for the owner loss of aesthetics due to transverse beam. From the calculation results it turns out that no special shear reinforcement is needed, adjustments by enlarging the column dimensions, plate strength or thickness. = 694 KN> Vn = 361,512 KN. To produce space efficiency that is expected, it is better to use plate flates. In terms of calculations it turns out that the plate flates need more reinforcement when compared to conventional plates. Keywords: conventional plate, plate flate,
