Abstract

Indonesia is a country with high earthquake risk. So Indonesia often experiences earthquakes and as a result of the earthquake waves cause damage to buildings range from minor damage to severe damage. Then it is necessary planing and implement earthquake-resistant building structures, especially in high-rise buildings. Another factor that needs to be considered is the function of the room which affects column height where when the column height is different it causes uneven stiffness from the ground floor to the top. The purpose of this study was to determine the effect of column height variations on the performance of multi-storey building structures in terms of shear forces, intersection between floor and buckling load (Pc). The method used in this study is the spectrum response method. Spectrum response is the maximum response of a single degree of freedom (SDOF) structure both acceleration, speed and displacement due to these structures are burdened by certain external forces. Before analyzing using the spectrum response method, structure models are made by varying the height of the 1st floor column into 3 variations. From the results of the analysis on building structure models with varying the height of the 1st floor column known, the higher the column the maximum base shear value increases. The higher the 1st floor column, the higher the intersection value between floors. The higher the column slenderness ratio value increases and the Euler buckling load decreases.
