Research related to graded concrete is continuedly conducted to create high strength, lighter specific gravity, and lower manufacturing costs. In this study, researchers aim to study the behaviour of structures using graded concrete as a construction material. Two buildings with different slenderness ratios are prepared using ETABS. The results show that the structural vibration time of all models, do not exceed the maximum allowable value. The use of graded concrete provides a significant effect in high-rise buildings so that the high-rise structures behave more rigid in responding to lateral loads. The trend of storey stiffness increase is at the minimum value at the lower level and is gradually increasing on the higher storey level. The application of graded concrete as building materials in multi-storey buildings can be applied in storey level above the 1st floor so that the factors of material characteristics will dominate rather than the behaviour of the structures to create efficient construction. The use of graded concrete can reduce the value of sway in each model. The reduction of the sway gradually increases on the upper floor of the building. This is related to the additional stiffness contributed by the graded concrete of beams against the slabs. © Published under licence by IOP Publishing Ltd.
